A game is structured playing, usually undertaken for enjoyment 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/games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).
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.
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.
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
