With the improvement of the perfect information game research, people gradually turn their research focus to the study of imperfect information game. Mahjong AI is a relatively complex typical representative of imperfect information game, whether from the average size of information set or the number of information sets. Therefore, with mahjong as the starting point, we can better study the game of imperfect information in complex situations. Under this background, this paper first introduces the rules of Mahjong, next analyzes the challenges faced by Mahjong AI due to its complex game rules, then summarizes the current research status of Mahjong AI from the perspective of the opponent and its own, and analyzes the advantages and disadvantages of each method. Finally, the future development direction of Mahjong AI is proposed.
