Mahjong is a traditional tile game in East Asia. Although randomness and luck affect playing, calculation and analysis can increase the chance of winning. The main aim of this project is to develop an AI that helps a player to play mahjong with reasonable suggestions of the moves to be done in the game. From the help of the program, a player will achieve a higher rate of winning. The challenges in this project are developing an effective algorithm, and having it applied on a game platform that have enough number of players. Tenhou.net is online game platform selected to test the AI???s strength versus human players. Game record from famous players are also used to prove the effectiveness of the AI.
