24 Game

The 24 Game is an arithmetical card game in which the object is to find a way to manipulate four integers so that the end result is 24. Addition, subtraction, multiplication, or division, and sometimes other operations, may be used to make four digits from one to nine equal 24. For example, card with the numbers 4,7,8,8, a possible solution is the following: (7-(8/8))*4=24.

The game has been played in Shanghai since the 1960s, using ordinary playing cards. Robert Sun commercialised the game and copyrighted it in 1988, introducing dedicated game cards bearing four numbers each, and sold it through his company, Easton, Pennsylvania-based Suntex International Inc. There are nine official editions of Suntex's 24 Game. A tournament-style competition, referred to as the 24 Challenge, is based on the 24 game.

Famous quotes containing the word game:

    Art is a concrete and personal and rather childish thing after all—no matter what people do to graft it into science and make it sociological and psychological; it is no good at all unless it is let alone to be itself—a game of make-believe, or re-production, very exciting and delightful to people who have an ear for it or an eye for it.
    Willa Cather (1873–1947)
