Don’t just play mahjong. Understand it.
Not a tile-matching game with a hint button — a coach that explains why a discard is right, across seven rule sets, and tracks whether you’re actually getting better.

The coach that reasons out loud
Most mahjong apps give you a silent hint: “discard this.” Mahjong Master Coach does the opposite — it shows its thinking.
Rank your options, tap Why?, and watch the coach think out loud in plain language: the priority, the candidate discards it weighed, and the trade-off — grounded in the real numbers. The coaching runs on-device using Apple’s on-device intelligence, so the “Ask the Coach” conversation is private and works on a plane. It grades your decision, not your luck.
Challenge a friend — same deal, no account
Because the game is deterministic, a whole deal fits in a QR code. Finish a hand, tap Challenge a Friend, and hand the code to someone else — they play the identical tiles on any device, then you compare scores. No login. No server. No internet. The format is open and published so other apps can implement it too.
What it does
A coach that reasons
Ranked considerations for every discard, with a “Why?” that explains the trade-off in plain language — speed against value, safety against progress.
Reads the table
Estimates what each opponent is holding from their discards and exposures, and tells you when to stop pushing and play safe.
Seven rule sets
Simplified, Hong Kong, Chinese Official, Japanese Riichi, Taiwanese, Sichuan Bloody, and American — all fully playable, not stubs.
The analysis lab
A decision-quality score and confidence read on every discard, a per-turn timeline of the moves that cost you, and replay-and-fork to try a hand differently.
Train, then prove it
Play coached to learn, then graded with no coaching to find out what stuck. Every game is scored and replayable move by move.
Progress you can see
A Master Score out of 10,000 built from knowledge, training, and real play — with streaks, daily rings, charts, and decay if you stop.
Solitaire too
A full layered tile-matching mode with guaranteed-solvable deals, a daily challenge, its own coach, and its own progression.
Your mahjong home base
Optional, in-app: mahjong news and events, a community and clubs directory, and every mahjong podcast with a built-in player.
