Ruleset guide
Chinese Mahjong vs American Mahjong
Mahjong variants share tiles and vocabulary, but procedure and scoring must stay attached to a named ruleset.
Context: Multiple rulesetsChinese MCR uses an open scoring catalogue; American Mahjong uses a current card of named hands, Jokers, and a Charleston pass.
Shared foundation

- Players still draw and discard.
- Equipment may look similar at a glance.
Defining rules
American sets commonly add Jokers, racks, and pushers, and valid hands depend on the current card.
- Do not validate American hands with the siteβs MCR checker.
- Chinese chow rules are not American hand recipes.
- The current card is separate from the set.
At the table
Use the official or organizer-approved document for disputes. Agree on minimums, bonuses, payments, and local options before dealing.
Key takeaways
- Both descend from the broad Mahjong family and use recognizable suit and honor tiles.
- American sets commonly add Jokers, racks, and pushers, and valid hands depend on the current card.
