Mahjong Mind: Learn & Play

Practice Riichi and MCR decisions, search 81 scoring patterns, and study American Mahjong with your own card. See why each move works.

Practice Mahjong decisions and understand the reasoning before your next hand.

CHOOSE, THEN CHECK Pick a discard, call, defense line, or score before revealing the explanation. Compare distance to a winning hand, improving tiles, waits, visible copies, danger, patterns, and points.

STUDY YOUR RULESET Practice five scored table styles: Riichi (Japanese), Hong Kong, Chinese Official (MCR), Taiwanese, and Singaporean Mahjong. Hand size, scoring, table flow, and terminology follow the rules you choose.

For American Mahjong, create or import your own card to study hand matching, scoring, discards, and Charleston choices. Practice jokers, exposures, and calls with the 152-tile set. No copyrighted annual card is included. The American trainer is separate from full-hand table play.
