American Mahjong Practice

American Mahjong Practice rethinks Mahjong for mobile with 2026 hands, daily challenges, and a leaderboard. Play offline, with large tiles and an optional open play mode and bots to practise. The Original American Mahjong App, ten years in the making, helps you learn the NMJL card anywhere.

Explore suggested hands sorted by overlapping tiles, see hand validations and corrections, track your progress with detailed stats, and tailor your sessions with hand filters. Features like replay/undo and house-rule open play give you flexible practice, whether solo or against opponents.
