Game of Chinese origin usually played by four persons with 144 domino-like tiles that are drawn and discarded until one player secures a winning hand. The object of play is similar to that of the rummy card games. It is probably of 19th-century origin. The name was coined by J. P. Babcock, who introduced the game to the West after World War I. The mah-jongg set includes a pair of dice, a quantity of tokens or chips used for scorekeeping, and a rack for keeping tiles upright and keeping their faces hidden from other players
