What is Mahjong:
Mahjong, also spelled majiang, mah jongg, and numerous other variants, is a game that originated in China. It is commonly played by four players (with some three-player variations found in Korea and Japan). The game and its regional variants are widely played throughout Eastern and South Eastern Asia and have a small following in Western countries. Similar to the Western card game rummy, mahjong is a game of skill, strategy, and calculation and involves a degree of chance.
