Learn mahjong. Score your hand with your camera. Then sharpen your game against the most advanced mahjong AI on iPhone — built for mahjong. Whether you've never held a tile or you've played for years, Mahjong Sensei makes you better at the table. Beginners learn the game step by step. Experienced players can score hands in seconds with the live camera and sharpen their play against the most advanced Mahjong AI ever on iOS. NEW TO MAHJONG? Point your camera at a tile and Sensei tells you what it is and what it's for. Then take the course: from the tiles to your first winning hand, and drills that turn the rules into instinct. WON A HAND? Point your camera at it. Sensei counts the faan and shows which tiles earned each one, so you get paid right and know why. Scoring follows your table: minimum faan, limit, flowers, or the official rulebook. READY TO GET GOOD? Practise against one of the most advanced Mahjong AIs on iPhone, as often as you like. Ask Sensei what it would discard at any point, and learn from the decision in real time. MAHJONG SENSEI PRO Practice without limits. One purchase, yours for good: • Every drill at full length, and fresh questions whenever you want them. • Clear, beginner-friendly explanations under every suggestion at the table. • No subscription. Pay once, keep it forever. Built for Hong Kong Mahjong today, with more styles on the way. No account, works offline, and photos never leave your device. Bring a Sensei to your next table.
