Nihon Pro Mahjong Renmei: Kounin Dojo Yaburi

Mahjong is a game for four players that originated in China. Mahjong involves skill, strategy, and calculation, as well as a certain degree of chance. Depending on the variation which is played, luck can be anything from a minor to a dominant factor in success. In Asia, mahjong is also popularly played as a gambling game. In the game, each player is dealt either thirteen or sixteen tiles in a hand (depending on the variation being played).

On their turn, players draw a tile and discard one, with the goal of making four or five melds (also depending on the variation) and one pair, or "head". Winning comes "on the draw", by drawing a new or discarded tile that completes the hand. Thus a winning hand actually contains fourteen (or seventeen) tiles.
