San-nin Mahjong — About this game
Play mahjong against two computer opponents, choosing the beginner level or the stronger advanced level. Draw a tile, select a discard and use the call menu when you want to chi, pon or kan. The program calculates scoring, but this is not a modern three-player rules preset: the original manual uses four-player-style payments with an unseen fourth share, so displayed totals need not balance between the three visible players.
