## What is Mahjong Master Coach?

Mahjong Master Coach is a single-player Mahjong game built like a fitness coach. Play AI opponents from Basic to Mahjong Wizard, with a coach that ranks your options, explains why, and reviews every game in plain language that never reads like a form letter.

• Learn by playing — a guided first game, lessons, and quizzes that track what you've mastered.
• A coach that explains — rank your options, tap Why?, and watch it think out loud: the priority, the candidates it weighed, and the trade-off, grounded in the real numbers. Coaching runs on-device and offline using Apple's on-device intelligence, so it stays private.
• The analysis lab — every discard gets a decision-quality score and an optional confidence read (best, good, or risky). A per-turn timeline shows the handful of moves that actually cost you, and an efficiency radar maps your strengths. Replay any hand and change one discard — the AI plays it forward so you can compare outcomes side by side. It grades your decision, not your luck.
• A Master Score out of 10,000 that rewards knowledge, training, and real games — and gently fades if you stop, so streaks matter.
• Seven rule sets — American (NMJL-style, with the Charleston and jokers), Hong Kong, Japanese Riichi, Chinese Official (MCR), Taiwanese 16-tile, Sichuan (blood-battle), and a Simplified beginner set — each with its own coaching and references.
• Mahjong Solitaire, too — layered tile-matching with boards that are guaranteed solvable, plus a daily challenge.
• Challenge a friend to the exact same deal with a QR code — they play the identical hand on any device, then you compare scores. No account. No internet. (Powered by the open Mahjong Portable Format.)
• Your mahjong home base — optional and in-app: mahjong news and events, a community and clubs directory, and mahjong podcasts with a built-in player.
• Clean and private — no ads, no gacha, no fan-service, no tracking. Plays fully offline.
