Games
A game is a structured activity, 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 concerned with the expression of ideas. 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 Mah-jongg solitaire).
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. The requirement for player interaction puts activities such as jigsaw puzzles and solitaire “games” into the category of puzzles rather than games.[1]
Attested as early as 2600 BC,[2][3] 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.[4]
Ludwig Wittgenstein was probably the first academic philosopher to address the definition of the word game. In his Philosophical Investigations,[5] Wittgenstein demonstrated that the elements of games, such as play, rules, and competition, all fail to adequately define what games are. He subsequently argued that the concept “game” could not be contained by any single definition, but that games must be looked at as a series of definitions that share a “family resemblance” to one another.
