Support The Mahjong Archive

Mahjong isn't one game. It's nine, each with its own rules, scoring, and traditions.
Most online guides teach "mahjong" generically and leave you confused when the rules contradict. The Archive solves that by teaching each variant as its own complete game—nine separate rulebooks, all sourced to official tournaments, national federations, or clearly flagged editorial rulings where the sources go silent.
What you're supporting:

Sourcing rules from official Chinese, Japanese, and American rulebooks (often reading the originals in their source language)
Maintaining verified chapters that pass the friends-at-a-table test: read it once, explain it once, play
Hosting a free website so anyone can learn, plus a forthcoming print book with worked examples, diagrams, and cheat sheets
Ongoing collaboration with regional experts to keep every variant accurate as rules evolve

This work takes time, research, and hosting costs. Every coffee helps keep the site alive and the research going.
