Nada Asatarou & Kojima Takeo no Jissen Mahjong Kyoushitsu — About this game
Practice Japanese mahjong with seven computer opponents, a professional tournament and two sets of scored questions. The hundred-problem training mode explains both correct and incorrect choices, while the thirty-question rank test asks about discards, waits and points. Adjust rules such as open tanyao, ippatsu and kan-ura dora before a match, then learn to balance hand shape with the situation. Two linked Game Boys also provide a direct human contest alongside the solo lessons. Open the menu and try the training questions before a full match. Move to a discard with Left/Right and confirm with A, then read the explanation. For CPU play choose an opponent and set the rules before selecting game start.
