Wittgenstein used games to show definitions can lack one essence
A game sets a challenge inside rules, usually for play, contest, or learning—solo or social, with or without gear. The Royal Game of Ur and Senet reach back to at least 2600 BCE. Wittgenstein likened game to a family-resemblance word; Bernard Suits later defined playing as voluntary obstacles.
Games appear universal in human cultures. Philosophers treat them as laboratories for rules and meaning; psychologists link play to cognitive growth. Wittgenstein's Investigations argues no single feature covers all games—only overlapping similarities—undercutting tidy essential definitions. Adults at play can enter the absorbed state known as flow, and game theory borrows the structure of games to model choices in economics and evolutionary biology. Today the global video game industry earns more each year than film or music.
Suits, in Grasshopper: Games, Life and Utopia from 1978, described play as pursuing a goal using only rule-approved means that deliberately rule out more efficient ones. French sociologist Roger Caillois, in his 1961 book Les jeux et les hommes, required a game to be fun, separate in time and place, uncertain, non-productive, rule-governed and fictitious. Designer Greg Costikyan stressed decisions about resources, which by his test excludes Chutes and Ladders, Candy Land and War. Katie Salen and Eric Zimmerman emphasized artificial conflict with a measurable result, and Jane McGonigal reduced all games to a goal, rules, feedback and voluntary participation.
A cuneiform tablet from the second century BCE records rules for the Royal Game of Ur, the earliest known written game design, and Senet mattered enough in Egypt to appear in tomb art. Mancala has Neolithic versions from Jordan dated to about 6900 BCE. Go is described as early as China's Spring and Autumn period and held off computers until the deep-learning program AlphaGo. Chess likely descends from chaturanga in India's Gupta Empire around the sixth century CE, passed through Persia as chatrang, reached Europe through Moorish Spain and neared its modern shape by the fifteenth century. Playing cards may come from Tang China, between 618 and 907 CE, and arrived in Europe via the Mamluk Sultanate in the fourteenth century.
