Riichi Mahjong is the Japanese variant to the Chinese game for four players. RMahjong is the computer implementation of this game. RMahjong allows you to play the game over a network, missing players can be replaced by computer players.
I have implemented RMahjong few years ago for fun, and I am not working on it actively now. Most of rules are working; however some rarely occuring rules are missing. The original web pages was not preserved and I do not remember exactly what rules are missing.
