MCR Dojo

MCR Dojo — learn Chinese Official Mahjong (国标麻将) scoring the way you actually remember it: by solving small, focused quizzes with instant feedback.

WHY MCR DOJO

Tried to study the 81-fan rules but bounced off the rulebook? Played a few games but still can't tell which fan you're scoring? MCR Dojo splits the official 81-fan ruleset into ten chapters and hundreds of bite-sized quiz questions. Every five minutes of practice moves you forward — no thick book required.

WHAT'S INSIDE

• Chapter-based curriculum: from basic fan to high-value combinations, each chapter split into sub-levels you unlock as you go.

• Instant feedback: every answer immediately shows the correct fan total, the fan-by-fan breakdown, and an explanation. Misreads are obvious.

• Full 81-fan reference: every fan with description, canonical example hand, and practical tips.

• Scoring showcase: curated example hands with engine-computed breakdowns and notes on which fan absorbs which.

• Mistake practice: missed questions are tracked and re-served in a dedicated review mode so you can target your weak spots.

• Progress and stats: per-chapter completion and accuracy, so you always know where you stand.

• Bilingual UI: Simplified Chinese, Traditional Chinese (Taiwan / Hong Kong) — all native-quality.

WHO IT'S FOR

• Mahjong newcomers who want to learn 国标 rules but find the rulebook a wall;

• Casual players who can't yet name the fan they just won on;

• Intermediate players speeding up their scoring intuition;

• Tournament players drilling for competition.

WHY US

Fan totals come from an open-source mahjong engine — the breakdown you see is the actual computation, not a guess. The UI is built for learning: no ads, no in-app purchase interruptions. Content updates regularly.
