Mahjong Mind: Learn

Choose a discard, then see why it works. Learn mahjong through guided lessons, practice hands, scoring drills, and full-hand play against on-device opponents. Study Japanese Riichi, Hong Kong, Chinese Official (MCR), Taiwanese, and Singaporean mahjong. The lessons, scoring, and table rules follow your chosen variant. Foundations courses introduce the tiles, hand shapes, and rules, with short questions to check what you learned. Practice tile efficiency, waits, calls, defense, and push-or-fold decisions. Compare your choice with an alternative and check how far your hand is from a win, which tiles improve it, the visible copies, patterns, and points. Danger and strategic value estimates are labeled. Play a five-hand Daily Challenge or focus on a skill. In full-hand play, choose Beginner, Club, or Strong opponents. Review a finished hand one decision at a time, retry a discard from its original position, or analyze a hand of your own. Mistake review brings back the hands you need to practice. Learn scoring with worked hands and a searchable 81-pattern MCR reference. Track practice accuracy, progress, and streaks, and share challenges with friends. For American mahjong, practice Charleston choices, jokers, and exposures. Import or create your own card for hand matching, scoring, and card-based strategy. No annual NMJL card is included. American practice is separate from full-hand table play. Practice on iPhone and iPad with larger text, VoiceOver, and Reduce Motion. No ads or account required. This is an educational trainer. No real money is staked and no wagers are placed. Lessons, daily practice, full-hand play, and manual hand scoring are free. An optional one-time purchase adds defense, Push/Fold, and scoring drills, mistake practice, decision retry, imported-log analysis, photo recognition, detailed trends, and Traditional and Minimal tile faces.
