Mahjong Sensei

Scan tiles, count faan, and practice against Sensei AI—trained through over 100 million self-play games—to understand every discard and improve your game.

Read the hand. Count the faan. Make your next move with confidence.

Mahjong Sensei turns your iPhone or iPad into a private, table-side coach for Hong Kong Mahjong. Point the camera at physical tiles, confirm what Sensei sees, then get a clear score, tile count, or recommendation—with the reason behind it.

POINT. CHECK. UNDERSTAND.

1. Point your camera at the tiles—no manual tile picker.
2. Check the recognized hand and table context.
3. Understand the score or suggestion, then see why it works.

WHAT YOU CAN DO

• Recognize tiles: Scan an unfamiliar tile to see its English name, Traditional Chinese name, Jyutping pronunciation, suit, number, and role. • Score a winning hand: Count Hong Kong faan with a rules-based engine and see which tiles created each scoring pattern. • Track what’s live: Count visible tiles between hands, dim dead copies, and highlight the tiles you’re waiting for. • Learn at the table: Use the bilingual tile guide, scoring cheat sheet, and seat-and-wind references without holding up the game. • Practice and improve: Play complete four-wind matches against Sensei AI, trained through 96 million self-play decisions, and learn from its coaching on every discard. • Match your house rules: Choose your minimum faan, limit, flower scoring, and common table conventions.

PRIVATE BY DESIGN

Tile recognition runs on your device. Your images never leave your iPhone or iPad, no account is required, and the app works offline.

Made for curious and improving players who are tired of guessing, counting twice, or wondering why one discard is better than another.

Hong Kong Mahjong is available at launch. Additional mahjong styles will only arrive when their own rules and coaching are ready.
