Improve your memory skills and sharpen your mind by playing mahjong. Although the game originated in China in the late 19th century near Shanghai, this course will be based on American mahjong. This is not the same as the computer mahjong games where the tiles are matched within mosaics and then disappear. The game is made up of tiles, which have identified suits, and the objective is to form specific hands or sets of tiles (as in many card games).
