Mahjong trains a sharp eye and a quick mind, while developing patience and persistence. You play the game by matching identical tiles, or tiles that are in the same wildcard group.

You start with a board covered with 144 tiles. You can match only the free tiles. A tile is free if it doesn't have tiles above it or tiles in direct contact both to the right and to the left. The goal of the game is to match and remove all tiles from a board.
