A game is a structured form of play, usually undertaken for entertainment or fun, and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports or games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).

Games are sometimes played purely for enjoyment, sometimes for achievement or reward as well. They can be played alone, in teams, or online; by amateurs or by professionals. The players may have an audience of non-players, such as when people are entertained by watching a chess championship. On the other hand, players in a game may constitute their own audience as they take their turn to play. Often, part of the entertainment for children playing a game is deciding who is part of their audience and who is a player.

Key components of games are goals, rules, challenge, and interaction. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational, or psychological role.

Attested as early as 2600 BC, games are a universal part of human experience and present in all cultures. The Royal Game of Ur, Senet, and Mancala are some of the oldest known games.

Definitions

Ludwig Wittgenstein

Ludwig Wittgenstein was probably the first academic philosopher to address the definition of the word game. In his Philosophical Investigations, Wittgenstein argued that the elements of games, such as play, rules, and competition, all fail to adequately define what games are. From this, Wittgenstein concluded that people apply the term game to a range of disparate human activities that bear to one another only what one might call family resemblances. As the following game definitions show, this conclusion was not a final one and today many philosophers, like Thomas Hurka, think that Wittgenstein was wrong and that Bernard Suits' definition is a good answer to the problem.

Children's Games, 1560, Pieter Bruegel the Elder

Roger Caillois

French sociologist Roger Caillois, in his book Les jeux et les hommes (Games and Men), defined a game as an activity that must have the following characteristics:

• fun: the activity is chosen for its light-hearted character
• separate: it is circumscribed in time and place
• uncertain: the outcome of the activity is unforeseeable
• non-productive: participation does not accomplish anything useful
• governed by rules: the activity has rules that are different from everyday life
• fictitious: it is accompanied by the awareness of a different reality

Chris Crawford

Game designer Chris Crawford defined the term in the context of computers. using a series of dichotomies:

1. Creative expression is art if made for its own beauty, and entertainment if made for money.
2. A piece of entertainment is a plaything if it is interactive. Movies and books are cited as examples of non-interactive entertainment.
3. If no goals are associated with a plaything, it is a toy. (Crawford notes that by his definition, (a) a toy can become a game element if the player makes up rules, and (b) The Sims and SimCity are toys, not games.) If it has goals, a plaything is a challenge.
4. If a challenge has no "active agent against whom you compete", it is a puzzle; if there is one, it is a conflict. (Crawford admits that this is a subjective test. Video games with noticeably algorithmic artificial intelligence can be played as puzzles; these include the patterns used to evade ghosts in Pac-Man.)
5. Finally, if the player can only outperform the opponent, but not attack them to interfere with their performance, the conflict is a competition. (Competitions include racing and figure skating.) However, if attacks are allowed, then the conflict qualifies as a game.

Crawford's definition may thus be rendered as: an interactive, goal-oriented activity made for money, with active agents to play against, in which players (including active agents) can interfere with each other. 

Other definitions, however, as well as history, show that entertainment and games are not necessarily undertaken for monetary gain.

Other definitions

• "A game is a system in which players engage in an artificial conflict, defined by rules, that results in a quantifiable outcome." (Katie Salen and Eric Zimmerman)
• "A game is a form of art in which participants, termed players, make decisions in order to manage resources through game tokens in the pursuit of a goal." (Greg Costikyan) According to this definition, some "games" that do not involve choices, such as Chutes and Ladders, Candy Land, and War are not technically games any more than a slot machine is.
• "A game is an activity among two or more independent decision-makers seeking to achieve their objectives in some limiting context." (Clark C. Abt)
• "At its most elementary level then we can define game as an exercise of voluntary control systems in which there is an opposition between forces, confined by a procedure and rules in order to produce a disequilibrial outcome." (Elliot Avedon and Brian Sutton-Smith)
• "A game is a form of play with goals and structure." (Kevin J. Maroney)
• "to play a game is to engage in activity directed toward bringing about a specific state of affairs, using only means permitted by specific rules, where the means permitted by the rules are more limited in scope than they would be in the absence of the rules, and where the sole reason for accepting such limitation is to make possible such activity." (Bernard Suits)
• "When you strip away the genre differences and the technological complexities, all games share four defining traits: a goal, rules, a feedback system, and voluntary participation." (Jane McGonigal)

Gameplay elements and classification

Games can be characterized by "what the player does". This is often referred to as gameplay. Major key elements identified in this context are tools and rules that define the overall context of game.

Tools

A selection of pieces from different games. From top: Chess pawns, marbles, Monopoly tokens, dominoes, Monopoly hotels, jacks and checkers pieces.

Games are often classified by the components required to play them (e.g. miniatures, a ball, cards, a board and pieces, or a computer). In places where the use of leather is well-established, the ball has been a popular game piece throughout recorded history, resulting in a worldwide popularity of ball games such as rugby, basketball, soccer (football), cricket, tennis, and volleyball. Other tools are more idiosyncratic to a certain region. Many countries in Europe, for instance, have unique standard decks of playing cards. Other games such as chess may be traced primarily through the development and evolution of its game pieces.

Many game tools are tokens, meant to represent other things. A token may be a pawn on a board, play money, or an intangible item such as a point scored.

Games such as hide-and-seek or tag do not use any obvious tool; rather, their interactivity is defined by the environment. Games with the same or similar rules may have different gameplay if the environment is altered. For example, hide-and-seek in a school building differs from the same game in a park; an auto race can be radically different depending on the track or street course, even with the same cars.

Rules and aims

Whereas games are often characterized by their tools, they are often defined by their rules. While rules are subject to variations and changes, enough change in the rules usually results in a "new" game. For instance, baseball can be played with "real" baseballs or with wiffleballs. However, if the players decide to play with only three bases, they are arguably playing a different game. There are exceptions to this in that some games deliberately involve the changing of their own rules, but even then there are often immutable meta-rules.

Rules generally determine the time-keeping system, the rights and responsibilities of the players, and each player's goals. Player rights may include when they may spend resources or move tokens.

The rules of a game are to be distinguished from its aims. For most competitive games, the ultimate ‘aim’ is winning: in this sense, checkmate is the aim of chess. Common win conditions are being first to amass a certain quota of points or tokens (as in Settlers of Catan), having the greatest number of tokens at the end of the game (as in Monopoly), or some relationship of one's game tokens to those of one's opponent (as in chess's checkmate). However, when we talk about the aims of a game, we also refer to intermediate aims: the things that you have to do in order to win the game. For instance, an intermediate aim in football is to score goals, because scoring goals will increase your likelihood to win the game (but isn't alone sufficient to win the game). 

Aims are not just a 'special' kind of rules: the difference between the rules of a game and the aims of a game is a fundamental one. This can be seen by considering some examples. The aim of chess is to checkmate, but although it is expected that players will try to checkmate each other, it is not a rule of chess that a player must checkmate the other player whenever he can (as a matter of fact, unskilled players often fail to take the opportunity to do so). Similarly, it is not a rule of football that a player must score a goal if he shoots a penalty (it is only expected, and not required, that he will try). On a general level, the distinction between the rules and the aims of a game can be characterised as follows: an aim identifies a sufficient condition for successful action, whereas the rule identifies a necessary condition for permissible action. While meeting the aims often requires a certain degree of skill and (in some cases) luck, following the rules of a game merely requires knowledge of the rules and some careful attempt to follow them; it rarely (if ever) requires luck or demanding skills.

Skill, strategy, and chance

A game's tools and rules will result in its requiring skill, strategy, luck, or a combination thereof, and are classified accordingly.

Games of skill include games of physical skill, such as wrestling, tug of war, hopscotch, target shooting, and stake, and games of mental skill such as checkers and chess. Games of strategy include checkers, chess, Go, arimaa, and tic-tac-toe, and often require special equipment to play them. Games of chance include gambling games (blackjack, Mahjong, roulette, etc.), as well as snakes and ladders and rock, paper, scissors; most require equipment such as cards or dice. However, most games contain two or all three of these elements. For example, American football and baseball involve both physical skill and strategy while tiddlywinks, poker, and Monopoly combine strategy and chance. Many card and board games combine all three; most trick-taking games involve mental skill, strategy, and an element of chance, as do many strategic board games such as Risk, Settlers of Catan, and Carcassonne.

Single-player games

Most games require multiple players. However, single-player games are unique in respect to the type of challenges a player faces. Unlike a game with multiple players competing with or against each other to reach the game's goal, a one-player game is a battle solely against an element of the environment (an artificial opponent), against one's own skills, against time, or against chance. Playing with a yo-yo or playing tennis against a wall is not generally recognized as playing a game due to the lack of any formidable opposition. Many games described as "single-player" may be termed actually puzzles or recreations.

Multiplayer games

"Multiplayer game" redirects here. For multiplayer video games, see Multiplayer video game.

 

The Card Players by Lucas van Leyden (1520) depicting a multiplayer card game.

A multiplayer game is a game of several players who may be independent opponents or teams. Games with many independent players are difficult to analyze formally using game theory as the players may form and switch coalitions. The term "game" in this context may mean either a true game played for entertainment, or a competitive activity describable in principle by mathematical game theory.

Game theory

John Nash proved that games with several players have a stable solution provided that coalitions between players are disallowed. Nash won the Nobel prize for economics for this important result which extended von Neumann's theory of zero-sum games. Nash's stable solution is known as the Nash equilibrium.

If cooperation between players is allowed, then the game becomes more complex; many concepts have been developed to analyze such games. While these have had some partial success in the fields of economics, politics and conflict, no good general theory has yet been developed.

In quantum game theory, it has been found that the introduction of quantum information into multiplayer games allows a new type of equilibrium strategy not found in traditional games. The entanglement of players's choices can have the effect of a contract by preventing players from profiting from what is known as betrayal.

Types

Tug of war is an easily organized, impromptu game that requires little equipment

 

Games can take a variety of forms, from competitive sports to board games and video games.

Sports

Association football is a popular sport worldwide.

Many sports require special equipment and dedicated playing fields, leading to the involvement of a community much larger than the group of players. A city or town may set aside such resources for the organization of sports leagues.

Popular sports may have spectators who are entertained just by watching games. A community will often align itself with a local sports team that supposedly represents it (even if the team or most of its players only recently moved in); they often align themselves against their opponents or have traditional rivalries. The concept of fandom began with sports fans.

Certain competitive sports, such as racing and gymnastics, are not games by definitions such as Crawford's (see above) – despite the inclusion of many in the Olympic Games – because competitors do not interact with their opponents; they simply challenge each other in indirect ways.

Lawn games

Lawn games are outdoor games that can be played on a lawn; an area of mowed grass (or alternately, on graded soil) generally smaller than a sports field (pitch). Variations of many games that are traditionally played on a sports field are marketed as "lawn games" for home use in a front or back yard. Common lawn games include horseshoes, sholf, croquet, bocce, lawn bowls, and stake.

Tabletop games

A tabletop game is a game where the elements of play are confined to a small area and require little physical exertion, usually simply placing, picking up and moving game pieces. Most of these games are played at a table around which the players are seated and on which the game's elements are located. However, many games falling into this category, particularly party games, are more free-form in their play and can involve physical activity such as mime. Still, these games do not require a large area in which to play them, large amounts of strength or stamina, or specialized equipment other than what comes in a box.

Dexterity and coordination games

This class of games includes any game in which the skill element involved relates to manual dexterity or hand-eye coordination, but excludes the class of video games (see below). Games such as jacks, paper football, and Jenga require only very portable or improvised equipment and can be played on any flat level surface, while other examples, such as pinball, billiards, air hockey, foosball, and table hockey require specialized tables or other self-contained modules on which the game is played. The advent of home video game systems largely replaced some of these, such as table hockey, however air hockey, billiards, pinball and foosball remain popular fixtures in private and public game rooms. These games and others, as they require reflexes and coordination, are generally performed more poorly by intoxicated persons but are unlikely to result in injury because of this; as such the games are popular as drinking games. In addition, dedicated drinking games such as quarters and beer pong also involve physical coordination and are popular for similar reasons.

Board games

Parcheesi is an American adaptation of a Pachisi, originating in India.

Board games use as a central tool a board on which the players' status, resources, and progress are tracked using physical tokens. Many also involve dice or cards. Most games that simulate war are board games (though a large number of video games have been created to simulate strategic combat), and the board may be a map on which the players' tokens move. Virtually all board games involve "turn-based" play; one player contemplates and then makes a move, then the next player does the same, and a player can only act on their turn. This is opposed to "real-time" play as is found in some card games, most sports and most video games.

Some games, such as chess and Go, are entirely deterministic, relying only on the strategy element for their interest. Such games are usually described as having "perfect information"; the only unknown is the exact thought processes of one's opponent, not the outcome of any unknown event inherent in the game (such as a card draw or die roll). Children's games, on the other hand, tend to be very luck-based, with games such as Candy Land and Chutes and Ladders having virtually no decisions to be made. By some definitions, such as that by Greg Costikyan, they are not games since there are no decisions to make which affect the outcome. Many other games involving a high degree of luck do not allow direct attacks between opponents; the random event simply determines a gain or loss in the standing of the current player within the game, which is independent of any other player; the "game" then is actually a "race" by definitions such as Crawford's.

Most other board games combine strategy and luck factors; the game of backgammon requires players to decide the best strategic move based on the roll of two dice. Trivia games have a great deal of randomness based on the questions a person gets. German-style board games are notable for often having rather less of a luck factor than many board games.

Board game groups include race games, roll-and-move games, abstract strategy games, word games, and wargames, as well as trivia and other elements. Some board games fall into multiple groups or incorporate elements of other genres: Cranium is one popular example, where players must succeed in each of four skills: artistry, live performance, trivia, and language.

Card games

Playing Cards, by Theodoor Rombouts, 17th century

Card games use a deck of cards as their central tool. These cards may be a standard Anglo-American (52-card) deck of playing cards (such as for bridge, poker, Rummy, etc.), a regional deck using 32, 36 or 40 cards and different suit signs (such as for the popular German game skat), a tarot deck of 78 cards (used in Europe to play a variety of trick-taking games collectively known as Tarot, Tarock or Tarocchi games), or a deck specific to the individual game (such as Set or 1000 Blank White Cards). Uno and Rook are examples of games that were originally played with a standard deck and have since been commercialized with customized decks. Some collectible card games such as Magic: The Gathering are played with a small selection of cards that have been collected or purchased individually from large available sets. 

Some board games include a deck of cards as a gameplay element, normally for randomization or to keep track of game progress. Conversely, some card games such as Cribbage use a board with movers, normally to keep score. The differentiation between the two genres in such cases depends on which element of the game is foremost in its play; a board game using cards for random actions can usually use some other method of randomization, while Cribbage can just as easily be scored on paper. These elements as used are simply the traditional and easiest methods to achieve their purpose.

Dice games

Students using dice to improve numeracy skills. They roll three dice, then use basic math operations to combine those into a new number which they cover on the board. The goal is to cover four squares in the row.

Dice games use a number of dice as their central element. Board games often use dice for a randomization element, and thus each roll of the dice has a profound impact on the outcome of the game, however dice games are differentiated in that the dice do not determine the success or failure of some other element of the game; they instead are the central indicator of the person's standing in the game. Popular dice games include Yahtzee, Farkle, Bunco, Liar's dice/Perudo, and Poker dice. As dice are, by their very nature, designed to produce apparently random numbers, these games usually involve a high degree of luck, which can be directed to some extent by the player through more strategic elements of play and through tenets of probability theory. Such games are thus popular as gambling games; the game of Craps is perhaps the most famous example, though Liar's dice and Poker dice were originally conceived of as gambling games.

Domino and tile games

Domino games are similar in many respects to card games, but the generic device is instead a set of tiles called dominoes, which traditionally each have two ends, each with a given number of dots, or "pips", and each combination of two possible end values as it appears on a tile is unique in the set. The games played with dominoes largely center around playing a domino from the player's "hand" onto the matching end of another domino, and the overall object could be to always be able to make a play, to make all open endpoints sum to a given number or multiple, or simply to play all dominoes from one's hand onto the board. Sets vary in the number of possible dots on one end, and thus of the number of combinations and pieces; the most common set historically is double-six, though in more recent times "extended" sets such as double-nine have been introduced to increase the number of dominoes available, which allows larger hands and more players in a game. Muggins, Mexican Train, and Chicken Foot are very popular domino games. Texas 42 is a domino game more similar in its play to a "trick-taking" card game.

Variations of traditional dominoes abound: Triominoes are similar in theory but are triangular and thus have three values per tile. Similarly, a game known as Quad-Ominos uses four-sided tiles.

Some other games use tiles in place of cards; Rummikub is a variant of the Rummy card game family that uses tiles numbered in ascending rank among four colors, very similar in makeup to a 2-deck "pack" of Anglo-American playing cards. Mahjong is another game very similar to Rummy that uses a set of tiles with card-like values and art.

Lastly, some games use graphical tiles to form a board layout, on which other elements of the game are played. Settlers of Catan and Carcassonne are examples. In each, the "board" is made up of a series of tiles; in Settlers of Catan the starting layout is random but static, while in Carcassonne the game is played by "building" the board tile-by-tile. Hive, an abstract strategy game using tiles as moving pieces, has mechanical and strategic elements similar to chess, although it has no board; the pieces themselves both form the layout and can move within it.

Pencil and paper games

Pencil and paper games require little or no specialized equipment other than writing materials, though some such games have been commercialized as board games (Scrabble, for instance, is based on the idea of a crossword puzzle, and tic-tac-toe sets with a boxed grid and pieces are available commercially). These games vary widely, from games centering on a design being drawn such as Pictionary and "connect-the-dots" games like sprouts, to letter and word games such as Boggle and Scattergories, to solitaire and logic puzzle games such as Sudoku and crossword puzzles.

Guessing games

A guessing game has as its core a piece of information that one player knows, and the object is to coerce others into guessing that piece of information without actually divulging it in text or spoken word. Charades is probably the most well-known game of this type, and has spawned numerous commercial variants that involve differing rules on the type of communication to be given, such as Catch Phrase, Taboo, Pictionary, and similar. The genre also includes many game shows such as Win, Lose or Draw, Password and $25,000 Pyramid.

Video games

Video games are computer- or microprocessor-controlled games. Computers can create virtual spaces for a wide variety of game types. Some video games simulate conventional game objects like cards or dice, while others can simulate environs either grounded in reality or fantastical in design, each with its own set of rules or goals.

A computer or video game uses one or more input devices, typically a button/joystick combination (on arcade games); a keyboard, mouse or trackball (computer games); or a controller or a motion sensitive tool (console games). More esoteric devices such as paddle controllers have also been used for input.

There are many genres of video game; the first commercial video game, Pong, was a simple simulation of table tennis. As processing power increased, new genres such as adventure and action games were developed that involved a player guiding a character from a third person perspective through a series of obstacles. This "real-time" element cannot be easily reproduced by a board game, which is generally limited to "turn-based" strategy; this advantage allows video games to simulate situations such as combat more realistically. Additionally, the playing of a video game does not require the same physical skill, strength or danger as a real-world representation of the game, and can provide either very realistic, exaggerated or impossible physics, allowing for elements of a fantastical nature, games involving physical violence, or simulations of sports. Lastly, a computer can, with varying degrees of success, simulate one or more human opponents in traditional table games such as chess, leading to simulations of such games that can be played by a single player.

In more open-ended computer simulations, also known as sandbox-style games, the game provides a virtual environment in which the player may be free to do whatever they like within the confines of this universe. Sometimes, there is a lack of goals or opposition, which has stirred some debate on whether these should be considered "games" or "toys". (Crawford specifically mentions Will Wright's SimCity as an example of a toy.)

Online games

Online games have been part of culture from the very earliest days of networked and time-shared computers. Early commercial systems such as Plato were at least as widely famous for their games as for their strictly educational value. In 1958, Tennis for Two dominated Visitor's Day and drew attention to the oscilloscope at the Brookhaven National Laboratory; during the 1980s, Xerox PARC was known mainly for Maze War, which was offered as a hands-on demo to visitors.

Modern online games are played using an Internet connection; some have dedicated client programs, while others require only a web browser. Some simpler browser games appeal to demographic groups (notably women and the middle-aged) that otherwise play very few video games.

Role-playing games

Role-playing games, often abbreviated as RPGs, are a type of game in which the participants (usually) assume the roles of characters acting in a fictional setting. The original role playing games – or at least those explicitly marketed as such – are played with a handful of participants, usually face-to-face, and keep track of the developing fiction with pen and paper. Together, the players may collaborate on a story involving those characters; create, develop, and "explore" the setting; or vicariously experience an adventure outside the bounds of everyday life. Pen-and-paper role-playing games include, for example, Dungeons & Dragons and GURPS.

The term role-playing game has also been appropriated by the video game industry to describe a genre of video games. These may be single-player games where one player experiences a programmed environment and story, or they may allow players to interact through the internet. The experience is usually quite different from traditional role-playing games. Single-player games include Final Fantasy, Fable, The Elder Scrolls, and Mass Effect. Online multi-player games, often referred to as Massively Multiplayer Online role playing games, or MMORPGs, include RuneScape, EverQuest 2, Guild Wars, MapleStory, Anarchy Online, and Dofus. As of 2009, the most successful MMORPG has been World of Warcraft, which controls the vast majority of the market.

Business games

Business games can take a variety of forms, from interactive board games to interactive games involving different props (balls, ropes, hoops, etc.) and different kinds of activities. The purpose of these games is to link to some aspect of organizational performance and to generate discussions about business improvement. Many business games focus on organizational behaviors. Some of these are computer simulations while others are simple designs for play and debriefing. Team building is a common focus of such activities.

Simulation

The term "game" can include simulation or re-enactment of various activities or use in "real life" for various purposes: e.g., training, analysis, prediction. Well-known examples are war games and role-playing. The root of this meaning may originate in the human prehistory of games deduced by anthropology from observing primitive cultures, in which children's games mimic the activities of adults to a significant degree: hunting, warring, nursing, etc. These kinds of games are preserved in modern times.

Play (activity)

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Play_(activity) 

Playfulness by Paul Manship

Play is a range of intrinsically motivated activities done for recreational pleasure and enjoyment. Play is commonly associated with children and juvenile-level activities, but play occurs at any life stage, and among other higher-functioning animals as well, most notably mammals.

Many prominent researchers in the field of psychology, including Melanie Klein, Jean Piaget, William James, Sigmund Freud, Carl Jung and Lev Vygotsky have viewed play as confined to the human species, believing play was important for human development and using different research methods to prove their theories.

Play is often interpreted as frivolous; yet the player can be intently focused on their objective, particularly when play is structured and goal-oriented, as in a game. Accordingly, play can range from relaxed, free-spirited and spontaneous through frivolous to planned or even compulsive. Play is not just a pastime activity; it has the potential to serve as an important tool in numerous aspects of daily life for adolescents, adults, and cognitively advanced non-human species (such as primates). Not only does play promote and aid in physical development (such as hand-eye coordination), but it also aids in cognitive development and social skills, and can even act as a stepping stone into the world of integration, which can be a very stressful process. Play is something that most children partake in, but the way play is executed is different between cultures and the way that children engage with play varies universally.

Definitions

The seminal text in the field of play studies is the book Homo Ludens first published in 1944 with several subsequent editions, in which Johan Huizinga defines play as follows:

"Summing up the formal characteristic of play, we might call it a free activity standing quite consciously outside 'ordinary' life as being 'not serious' but at the same time absorbing the player intensely and utterly. It is an activity connected with no material interest, and no profit can be gained by it. It proceeds within its own proper boundaries of time and space according to fixed rules and in an orderly manner. It promotes the formation of social groupings that tend to surround themselves with secrecy and to stress the difference from the common world by disguise or other means."

This definition of play as constituting a separate and independent sphere of human activity is sometimes referred to as the "magic circle" notion of play, a phrase also attributed to Huizinga. Many other definitions exist. Jean Piaget stated, "the many theories of play expounded in the past are clear proof that the phenomenon is difficult to understand."

There are multiple aspects of play people home in on when defining it. One definition from Susanna Millar's The Psychology of Play defines play as: “any purposeful mental or physical activity performed either individually or group-wise in leisure time or at work for enjoyment, relaxation, and satisfaction of real-time or long term needs.” This definition particularly emphasizes the conditions and benefits to be gained under certain actions or activities related to play. Other definitions may focus on play as an activity that must follow certain characteristics including willingness to engage, uncertainty of the outcome, and productivity of the activity to society. 

Another definition of play from the twenty-first century comes from the National Playing Fields Association (NPFA). The definition reads as follows: “play is freely chosen, personally directed, intrinsically motivated behaviour that actively engages the child.” This definition focuses more on the child's freedom of choice and personal motivation related to an activity.

Forms

People having fun

Play can take the form of improvisation or pretense, interactive, performance, mimicry, games, sports, and thrill-seeking, such as extreme or dangerous sports (sky-diving, high-speed racing, etc.). Philosopher Roger Caillois wrote about play in his 1961 book Man, Play and Games and Stephen Nachmanovitch expanded on these concepts in his 1990 book Free Play: Improvisation in Life and Art. Nachmanovitch writes that:

Improvisation, composition, writing, painting, theater, invention, all creative acts are forms of play, the starting place of creativity in the human growth cycle, and one of the great primal life functions. Without play, learning and evolution are impossible. Play is the taproot from which original art springs; it is the raw stuff that the artist channels and organizes with all his learning and technique. (Free Play, p. 42)

Free play gives children the freedom to decide what they want to play and how it will be played. Both the activity and the rules are subject to change in this form, and children can make any changes to the rules or objectives of the play at any time. Some countries in the twenty-first century have added emphasis of free play into their values for children in early childhood such as Taiwan and Hungary.

Structured play has clearly defined goals and rules and such play is called a "game". Other play is unstructured or open-ended. Both types of play promote adaptive behaviors and mental states of happiness.

Sports with defined rules will take place within designated play spaces, such as sports fields where, in Soccer for example, players kick a ball in a certain direction and push opponents out of their way as they do so. While appropriate within the sport's play space, these same behaviors might be inappropriate or even illegal outside the playing field.

Other designed play spaces can be playgrounds with dedicated equipment and structures to promote active and social play. Some play spaces go even farther in specialization to bring the play indoors and will often charge admission as seen at Children's Museums, Science Centers, or Family Entertainment Centers. Family Entertainment Centers (or Play Zones) are typically For-Profit businesses purely for play and entertainment, while Children's Museums and Science Centers are typically Non-Profit organizations for educational entertainment.

The California-based National Institute for Play describes seven play patterns:

1. Attunement play, which establishes a connection, such as between newborn and mother.
2. Body play, in which an infant explores the ways in which his or her body works and interacts with the world, such as making funny sounds or discovering what happens in a fall.
3. Object play, such as playing with toys, banging pots and pans, handling physical things in ways that use curiosity.
4. Social play, play which involves others in activities such as tumbling, making faces, and building connections with another child or group of children.
5. Imaginative or pretend play, in which a child invents scenarios from his or her imagination and acts within them as a form of play, such as princess or pirate play.
6. Storytelling play, the play of learning and language that develops intellect, such as a parent reading aloud to a child, or a child retelling the story in his or her own words.
7. Creative play, by which one plays with imagination to transcend what is known in the current state, to create a higher state. For example, a person might experiment to find a new way to use a musical instrument, thereby taking that form of music to a higher plane; or, as Einstein was known to do, a person might wonder about things which are not yet known and play with unproven ideas as a bridge to the discovery of new knowledge.

Separate from self-initiated play, play therapy is used as a clinical application of play aimed at treating children who suffer from trauma, emotional issues and other problems.

Children

In young children, play is frequently associated with cognitive development and socialization. Play that promotes learning and recreation often incorporates toys, props, tools or other playmates. Play can consist of an amusing, pretend or imaginary activity alone or with another. Some forms of play are rehearsals or trials for later life events, such as "play fighting", pretend social encounters (such as parties with dolls), or flirting. Modern findings in neuroscience suggest that play promotes flexibility of mind, including adaptive practices such as discovering multiple ways to achieve a desired result, or creative ways to improve or reorganize a given situation (Millar, 1967; Shonkoff & Phillips, 2000).

Children playing in a sandbox

As children get older, they engage in board games, video games and computer play, and in this context the word gameplay is used to describe the concept and theory of play and its relationship to rules and game design. In their book, Rules of Play, researchers Katie Salen and Eric Zimmerman outline 18 schemas for games, using them to define "play", "interaction" and "design" formally for behaviorists. Similarly, in his book Half-Real: Video Games between Real Rules and Fictional Worlds, game researcher and theorist Jesper Juul explores the relationship between real rules and unreal scenarios in play, such as winning or losing a game in the real world when played together with real-world friends, but doing so by slaying a dragon in the fantasy world presented in the shared video game.

Play is explicitly recognized in Article 31 of the Convention on the Rights of the Child (adopted by the General Assembly of the United Nations, November 29, 1989), which declares:

• Parties recognize the right of the child to rest and leisure, to engage in play and recreational activities appropriate to the age of the child and to participate freely in cultural life and the arts.
• Parties shall respect and promote the right of the child to participate fully in cultural and artistic life and shall encourage the provision of appropriate and equal opportunities for cultural, artistic, recreational and leisure activities.

History of childhood playtime

American historian Howard Chudacoff has studied the interplay between parental control of toys and games and children's drive for freedom to play. In the colonial era, toys were makeshift and children taught each other very simple games with little adult supervision. The market economy of the 19th century enabled the modern concept of childhood as a distinct, happy life stage. Factory-made dolls and doll houses delighted young girls. Organized sports filtered down from adults and colleges, and boys learned to play with a bat, a ball and an impromptu playing field.

20th Century

With the rise of motor vehicle traffic in the 20th century, teenagers were increasingly organized into club sports supervised and coached by adults, with swimming taught at summer camps and through supervised playgrounds. Under the New Deal's Works Progress Administration, thousands of local playgrounds and ball fields opened, promoting softball especially as a sport for all ages and both sexes. By the 21st century, Chudacoff notes, the old tension between parental controls and a child's individual freedom was being played out in cyberspace.

Cultural differences of play

The act of play time is a cross-cultural phenomenon that is universally accepted and encouraged by most communities; however, it can differ in the ways that is performed.

Some cultures, such as Euro-American cultural heritages, encourage play time in order to stress cognitive benefits and the importance of learning how to care for one's self. Other cultures, such as people of African American or Asian American heritages, stress more group oriented learning and play where kids can learn what they can do with and for others. Parent interactions when it comes to playtime also differs drastically within communities. Parents in the Mayan culture do interact with their children in a playful mindset while parents in the United States tend to set aside time to play and teach their children through games and activities. In the Mayan community, children are supported in their playing but also encouraged to play while watching their parents do household work in order to become familiar with how to follow in their footsteps.

Elephant – Mud play

All around the world, children use different natural materials like stones, water, sand, leaves, fruits, sticks and a variety of resources to play. In addition, there are groups that have access to crafts, industrialized toys, electronics and video-games.

In Australia, games and sports are part of play. There, play can be considered as preparation for life and self- expression, like in many other countries.

Groups of children in Efe of the Democratic Republic of Congo can be seen making ‘food’ from dirt or pretending to shoot bows and arrows much like their elders. These activities are similar to other forms of play worldwide. For instance, children can be seen comforting their toy dolls or animals, anything that they have modeled from adults in their communities.

In Brazil, we can find children playing with balls, kites, marbles, pretend houses or mud kitchens, like in many other countries. In smaller communities they use mud balls, little stones or cashews to replace marbles.

At an indigenous community of Sierra Nevada de Santa Marta in Colombia, children's play is highly valued and encouraged by leaders and parents. They interact with the children of different ages and explore together different environments to let the children express themselves as part of the group.

Some children in the Sahara use clay figures as their forms of playful toys. Toys in general are a representation of cultural practices. They usually illustrate characters and objects of a community.

Play time can be used as a way for children to learn the different ways of their culture. Many communities use play to emulate work. The way in which children mimic work through their play can differ according to the opportunities they have access to, but it is something that tends to be promoted by adults.

Sports

Sportive activities are one of the most universal forms of play. Different continents have their own popular/dominant sports. For example, European, South American, and African countries enjoy soccer (also known as ‘football’ in Europe), while North American countries prefer basketball, ice hockey, baseball, or American football. In Asia, sports such as table tennis and badminton are played professionally; however soccer and basketball are played amongst common folks. Events such as The Olympic Games and FIFA World Cup showcase countries competing with each other and are broadcast all over the world. Sports can be played as a leisure activity or within a competition. According to sociologist Norbert Elias; it is an important part of "civilization process". Victory and defeat in sports can influence one's emotions to a point where everything else seems irrelevant. Sport fans can also imagine what it feels like to play for their preferred team. The feelings people experience can be so surreal that it affects their emotions and behavior.

Benefits in youth

Youth sport can provide a positive outcome for youth development. Research shows adolescents are more motivated and engaged in sports than any other activity, and these conditions predict a richer personal and interpersonal development. Anxiety, depression and obesity can stem from lack of activity and social interaction. There is a high correlation between the amount of time that youth spend playing sports and the effects of physical (e.g., better general health), psychological (e.g., subjective well being), academic (e.g., school grades), and social benefits (e.g., making friends). Electronics over the past 10 years have been looked as a form of playtime but researchers have found that most electronic play leads to lack of motivation, no social interaction and can lead to obesity. Play is originally based on the idea of children using their creativity while developing their imagination, dexterity, physical, cognitive and emotional strength. Dramatic play is common in younger children. For the youth community to benefit from playtime, the following are recommended:

• Give children ample, unscheduled time to be creative to reflect and decompress
• Give children “true” toys, such as blocks or dolls for creativity
• Youth should have a group of supportive people around them (teammates, coaches, and parents) with positive relationships
• Youth should possess skill development; such as physical, interpersonal, and knowledge about the sport
• Youth should be able to make their own decisions about their sport participation
• Youth should have experiences that are on par with their certain needs and developmental level

Research findings on benefits in youth

With regular participation in a variety of sports, children can develop and become more proficient at various sports skills (including, but not limited to, jumping, kicking, running, throwing, etc.) if the focus is on skill mastery and development.  Young people participating in sports also develop agility, coordination, endurance, flexibility, speed, and strength. More specifically, young athletes could develop the following:

• enhanced functioning and health of cardiorespiratory and muscular systems
• improved flexibility, mobility, and coordination
• increased stamina and strength
• increased likelihood of maintaining weight

Moreover, research shows that regular participation in sport and physical activity is highly associated with lowering the risk of diabetes, heart disease, obesity, and other related diseases. According to research by the Australian Early Childhood Mental Health Initiative, children can be assisted in dealing with and managing stress by developing their sense of optimism when playing sports. Young people also tend to be more nutrition-conscious in their food choices when participating in sport. Girls involved in sport tend associate with lower chance of teenage pregnancy, begin smoking, and/or developing breast cancer. Young athletes have shown lower levels of total cholesterol and other favorable profiles in serum lipid parameters associated with cardiovascular disease. Sport provides an arena for young people to be physically active and in result reduce the time spent in sedentary pursuits, such as watching TV and playing video games.

Adults

Although adults who engage in excessive amounts of play may find themselves described as "childish" or "young at heart" by less playful adults, play is an important activity, regardless of age. Creativity and happiness can result from adult play, where the objective can be more than fun alone, as in adult expression of the arts, or curiosity-driven science. Some adult "hobbies" are examples of such creative play. In creative professions, such as design, playfulness can remove more serious attitudes (such as shame or embarrassment) that impede brainstorming or artistic experimentation in design.

Imaginative play and role play may allow adult individuals to practice useful habits such as learned optimism, which is helpful in managing fear or terrors. Play also offers adults the opportunity to practice concepts that may not have been explicitly or formally taught (e.g. how to manage misinformation or deceit). Thus, even though play is just one of many tools used by effective adults, it remains a necessary one.

Workplace

There has been extensive research when it comes to the benefits of play amongst children, youth, and adolescence. Most commonly overlooked are the benefits of play for adults, more specifically, adults who spend a lot of time in the workplace. Many adults in North America are in the workforce and spend half of their waking hours in a workplace environment with little to no time for play. Play in this context refers to leisure-type activities with colleagues during lunch breaks or short breaks throughout the working day. Leisure activities could include, but are not limited to, different forms of physical sport activities, card games, board games, video games and interaction-based type video games, foosball, ping-pong, yoga, and boot-camp sessions.

Research shows that playing games may promote a persistent and optimistic motivational style and positive affect. Positive affect enhances people's experiences, enjoyment, and sense of satisfaction derived from the activity, during their engagement with a certain task. While people are engaged in their work, positive affect increases the satisfaction they feel from the work, and this has also been shown to increase their creativity and improve their performance on problem-solving tasks as well as other tasks. The development of a persistent motivational style charged with positive affect may lead to lasting work success.

Studies show that work and play are mutually supportive. Employees need to experience the sense of newness, flow, discovery and liveliness that play provides. By doing this, it will provide the employee with the sense that they are integrated within the organization, and therefore they will feel and perform better. By incorporating play at work, it will also result in more productivity, creativity and innovation, higher job satisfaction, greater workplace morale, stronger or new social bonds, improved job performance, a decrease in staff turnover, absenteeism and stress. Decreased stress leads to less illness, which results in lower health care costs. Play at work may help employees function and cope when under stress, refresh body and mind, encourage teamwork, trigger creativity, and increase energy while preventing burnout.

Studies show that companies that encourage play at work, whether short breaks throughout the day or during lunch breaks experience more success because it leads to positive emotion amongst employees. Risk taking, confidence in presenting novel ideas, and embracing unusual and fresh perspectives are common characteristics associated with play at work. Play can increase self-reported job satisfaction and well-being. Employees experiencing positive emotions are more cooperative, more social, and perform better when faced with complex tasks.

Contests, team-building exercises, fitness programs, mental health breaks and other social activities, will make the work environment fun, interactive, and rewarding. Also playfighting, i.e. playful fights or fictive disputes, may contribute to organizations and institutions, as in youth care settings. Staff tries to down-key playfight invitations to “treatment” or “learning,” but playfighting also offers youth and staff identificatory respite from the institutional regime. Wästerfors (2016) has found that playfighting is a recurrent pattern in the social life of a youth care institution and sits at the core of what inmates and staff have to deal with

Seniors

Older adults represent one of the fastest growing populations around the world. In fact, the United Nations predicted an increase of those aged 60 and above from 629 million in 2002 to approximately two billion in 2050 but increased life expectancy does not necessarily translate to a better quality of life. For this reason, research has begun to investigate methods to maintain and/or improve quality of life among older adults.

Similar to the data surrounding children and adults, play and activity are associated with improved health and quality of life among seniors. Additionally, play and activity tend to affect successful aging as well as boost well-being throughout the lifespan. Although children, adults, and seniors all tend to benefit from play, older adults often perform it in unique ways to account for possible issues, such as health restrictions, limited accessibility, and revised priorities. For this reason, elderly people may partake in physical exercise groups, interactive video games, and social forums specifically geared towards their needs and interests. One qualitative research study found older adults often chose to engage in specific games such as dominoes, checkers, and bingo for entertainment. Another study indicated a common pattern within game preferences among older adults; seniors often favor activities that encourage mental and physical fitness, incorporate past interests, have some level of competition, and foster a sense of belonging. Researchers investigating play in older adults are also interested in the benefits of technology and video games as therapeutic tools. Studies show these outlets can lower the risk of developing particular diseases, reduce feelings of social isolation and stress, as well as promote creativity and the maintenance of cognitive skills. As a result, play has been integrated into physiotherapy and occupational therapy interventions for seniors.

The ability to incorporate play into one's routine is important because these activities allow participants to express creativity, improve verbal and non-verbal intelligence as well as enhance balance. These benefits may be especially crucial to seniors because evidence shows cognitive and physical functioning declines with age. However, other research argues it might not be aging that is associated with the decline in cognitive and physical capabilities. More specifically, some studies indicate it could be the higher levels of inactivity within older adults that may have significant ramifications on their health and well-being.

With attention to these hypotheses, research shows play and activity tend to decline with age which may result in negative outcomes such as social isolation, depression, and mobility issues. American studies found that only 24% of seniors took part in regular physical activity and only 42% use the internet for entertainment purposes. In comparison to other age groups, the elderly are more likely to experience a variety of barriers, such as difficulty with environmental hazards and accessibility related issues, that may hinder their abilities to execute healthy play behaviours. Similarly, although playing may benefit seniors, it also has the potential to negatively impact their health. For example, those who play may be more susceptible to injury. Investigating these barriers may assist in the creation of useful interventions and/or the development of preventative measures, such as establishing safer recreational areas, that promote the maintenance of play behaviours throughout elderly life.

A significant amount of literature suggests a moderate level of play has numerous positive outcomes in the lives of senior citizens. In order to support and promote play within the older population, studies suggest institutions should set up more diverse equipment, improve conditions within recreational areas, and create more video games or online forums that appeal to the needs of seniors.

Other animals

Evolutionary psychologists believe that there must be an important benefit of play, as there are so many reasons to avoid it. Many animals are often injured during play, become distracted from predators, and expend valuable energy. In rare cases, play has even been observed between different species that are natural enemies such as a polar bear and a dog. Yet play seems to be a normal activity with animals who occupy the higher strata of their own hierarchy of needs. Animals on the lower strata, e.g. stressed and starving animals, generally do not play. However, in wild Assamese macaques physically active play is performed also during periods of low food availability and even if it is at the expense of growth, which strongly highlights the developmental and evolutionary importance of play.

The social cognitive complexity of numerous species, including dogs, have recently been explored in experimental studies. In one such study, conducted by Alexandra Horowitz of the University of California, the communication and attention-getting skills of dogs were investigated. In a natural setting, dyadic play behavior was observed; head-direction and posture was specifically noted. When one of the two dogs was facing away or otherwise preoccupied, attention-getting behaviors and signals (nudging, barking, growling, pawing, jumping, etc.) were used by the other dog to communicate the intent and/or desire to continue on with the dyadic play. Stronger or more frequent signaling was used if the attention of the other dog was not captured. These observations tell us that these dogs know how play behavior and signaling can be used to capture attention, communicate intent and desire, and manipulate one another. This characteristic and skill, called the "attention-getting skill" has generally only been seen in humans, but is now being researched and seen in many different species.

Observing play behavior in various species can tell us a lot about the player's environment (including the welfare of the animal), personal needs, social rank (if any), immediate relationships, and eligibility for mating. Play activity, often observed through action and signals, often serves as a tool for communication and expression. Through mimicry, chasing, biting, and touching, animals will often act out in ways so as to send messages to one another; whether it's an alert, initiation of play, or expressing intent. When play behavior was observed for a study in Tonkean macaques, it was discovered that play signals weren't always used to initiate play; rather, these signals were viewed primarily as methods of communication (sharing information and attention-getting).

One theory – "play as preparation" – was inspired by the observation that play often mimics adult themes of survival. Predators such as lions and bears play by chasing, pouncing, pawing, wrestling, and biting, as they learn to stalk and kill prey. Prey animals such as deer and zebras play by running and leaping as they acquire speed and agility. Hoofed mammals also practice kicking their hind legs to learn to ward off attacks. Indeed, time spent in physical play accelerates motor skill acquisition in wild Assamese macaques. While mimicking adult behavior, attacking actions such as kicking and biting are not completely fulfilled, so playmates do not generally injure each other. In social animals, playing might also help to establish dominance rankings among the young to avoid conflicts as adults.

John Byers, a zoologist at the University of Idaho, discovered that the amount of time spent at play for many mammals (e.g. rats and cats) peaks around puberty, and then drops off. This corresponds to the development of the cerebellum, suggesting that play is not so much about practicing exact behaviors, as much as building general connections in the brain. Sergio Pellis and colleagues at the University of Lethbridge in Alberta, Canada, discovered that play may shape the brain in other ways, too. Young mammals have an overabundance of brain cells in their cerebrum (the outer areas of the brain – part of what distinguishes mammals). There is evidence that play helps the brain clean up this excess of cells, resulting in a more efficient cerebrum at maturity.

Marc Bekoff (a University of Colorado evolutionary biologist) proposes a "flexibility" hypothesis that attempts to incorporate these newer neurological findings. It argues that play helps animals learn to switch and improvise all behaviors more effectively, to be prepared for the unexpected. There may, however, be other ways to acquire even these benefits of play: the concept of equifinality. The idea is that the social benefits of play for many animals, for example, could instead be garnered by grooming. Patrick Bateson maintains that equifinality is exactly what play teaches. In accordance with the flexibility hypothesis, play may teach animals to avoid "false endpoints". In other words, they will harness the childlike tendency to keep playing with something that works "well enough", eventually allowing them to come up with something that might work better, if only in some situations. This also allows mammals to build up various skills that could come in handy in entirely novel situations. A study on two species of monkeys Semnopithecus entellus and Macaca mulatta that came into association with each other during food provisioning by pilgrims at the Ambagarh Forest Reserve, near Jaipur, India, shows the interspecific interaction that developed between the juveniles of the two species when opportunity presented itself.

Development and learning

Learning through play has been long recognized as a critical aspect of childhood and child development. Some of the earliest studies of play started in the 1890s with G. Stanley Hall, the father of the child study movement that sparked an interest in the developmental, mental and behavioral world of babies and children. Play also promotes healthy development of parent-child bonds, establishing social, emotional and cognitive developmental milestones that help them relate to others, manage stress, and learn resiliency.

Modern research in the field of affective neuroscience (the neural mechanisms of emotion) has uncovered important links between role play and neurogenesis in the brain. For example, researcher Roger Caillois used the word ilinx to describe the momentary disruption of perception that comes from forms of physical play that disorient the senses, especially balance.

Studies have found that play and coping to daily stressors to be positively correlated in children. By playing, children regulate their emotions and this is important for adaptive functioning because without regulation, emotions could be overwhelming and stressful.

Evolutionary psychologists have begun to explore the phylogenetic relationship between higher intelligence in humans and its relationship to play, i.e., the relationship of play to the progress of whole evolutionary groups as opposed to the psychological implications of play to a specific individual.

Physical, mental and social

Various forms of play, whether it is physical or mental, have influenced cognitive abilities in individuals. As little as ten minutes of exercise (including physical play), can improve cognitive abilities. These researchers did a study and have developed an "exergame" which is a game that incorporates some physical movement but is by no means formal exercise. These games increase one's heart rate to the level of aerobics exercise and have proven to result in recognizable improvements in mental faculties In this study they use play in a way that incorporates physical activity that creates physical excursions. The results of the study had statistical significance. There were improvements in math by 3.4% and general improvements in recall memory by 4% among the participants of the study.

On the other hand, other research has focused on the cognitive effects of mentally stimulating play. Playing video games is one of the most common mediums of play for children and adults today. There has been mixed reviews on the effects of video games. Despite this, according to a research conducted by Hollis (2014), "[playing video games] was positively associated with skills strongly related to academic success, such as time management, attention, executive control, memory, and spatial abilities – when playing video game occurs in moderation".

Play can also influence one's social development and social interactions. Much of the research focuses on the influence play has on child social development. There are different forms of play that have been noted to influence child social development. One study conducted by (Sullivan, 2003) explores the influence of playing styles with mothers versus playing styles with fathers and how it influences child social development. This article explains that "integral to positive development is the child's social competence or, more precisely, the ability to regulate their own emotions and behaviors in the social contexts of early childhood to support the effective accomplishment of relevant developmental tasks.

Social benefits of play have been measured using basic interpersonal values such as getting along with peers. One of the social benefits that this researcher has uncovered is that play with parents has proven to reduce anxiety in children. Having play time with parents that involves socially acceptable behaviour makes it easier for children to relate to be more socially adjusted to peers at school or at play Social development involving child interaction with peers is thus an area of influence for playful interactions with parents and peers.

Play in educational practices

Anji play

Anji play 安吉游戏 in simplified Chinese 安吉遊戲 in traditional Chinese is an educational method based on children's self-directed play in outside spaces, using simple tools made of natural material. The teachers and instructors only observe and document the children's independent play. The method was created by Cheng Xueqin and is organized in two hours of free play when the children choose the available material they want to use and build structures to play.

While planning, experimenting, building and using the structures to play, the children have the opportunity to interact with peers, to think critically about what may work, to discuss the plan and organize the construction hard work. The process is observed and recorded by the teachers and instructors without intervention, even in instances of possible risk.

Before and after the two hours of play, the children have the opportunity to express their plans and discuss with their peers. After the play, they get the opportunity to draw, write or explain what they did. Then, they watch the videos recorded the same day and explain how they played and comment on each other's creations.

Anji play is also called “true play” and its guiding principles are love, risk, joy, engagement, and reflection. This method of self-initiated and self-directed play is applied at the pre-schools (to children from 3 to 6 years-old) in Anji county, East China.
