Play Pocket Mahjong (Japan edition · Japanese) Online

Pocket Mahjong puts a four-seat table on the Game Boy screen. Build a hand from the drawn tiles while watching what the other players discard, and decide whether a call helps the pattern you want to finish. The command window presents actions when they become available, so reading its choices is as important as picking a tile. A hurried discard can remove a useful connection; a patient one keeps options without forgetting the points at stake. Start with the basic rules, then learn how the same hand changes when another player's discard offers a different route.

Choose the rules and begin a hand. Left/right picks a discard and A commits it. When an action mark flashes, press up to open the command window, choose the available call or win, or B to pass without acting.
