What we publish
We create beginner lessons, terminology references, variant comparisons, strategy guides, printable tools, and carefully checked browser-game pages. Every guide names the ruleset when a detail is not shared across mahjong traditions.
Editorial principles
We favor primary and authoritative sources, distinguish documented history from legend, avoid reproducing copyrighted hand cards, and do not publish medical claims as fact. AI may support drafting and visual production, but pages are structured for source review, consistency checks, and human correction.
Corrections
Mahjong rules evolve through organizations, editions, and living table practice. If you find an error or a missing variant label, use the contact page and include the rule source you follow.
