About this Game

Born in 19th-century China and now played across the globe, Mahjong demands probability calculation, opponent reading, and the perfect balance of offense and defense. Simple to learn, but the layered scoring systems (yaku) give it a lifetime of strategic depth.
How to Play
Each player starts with 13 tiles. On your turn, draw one tile from the wall and discard one from your hand. You can claim other players' discards to form melds: Pon (three identical), Chi (three consecutive in one suit), or Kan (four identical).
To win, complete a 14-tile hand with four melds and one pair. Drawing the winning tile yourself is called Tsumo. Taking it from an opponent's discard is Ron. In Riichi Mahjong, you need at least one scoring pattern (yaku), and your score depends on which yaku you've got.
