No internet connection needed. This is the best way to learn the 2025 card. NEW - NMJL Rules: The app alerts players when a move doesn’t follow NMJL rules, helping beginning players learn correct American Mahjong play. Suggested Hands: All possible hand combinations are evaluated and sorted by the highest matching tile count. Play one of these hands or any hand you want. See the combinations of hands with the most overlapping tiles. Develop your strategies selecting hands. Open Play: Try different strategies with Replay and Undo. Tiles can be moved around freely with NMJL rules disabled. Play Solo or Against Bots Easy Bots never declare Mahjong. Play each hand until the wall is empty. To play against Bots select the Basic Bots option in Settings. Filters: Filter out previous wins and play the whole card. Filter sections of the card and practice a section at time.
