The short answer: American mahjong uses 152 tiles — 144 standard plus 8 jokers — while Chinese mahjong uses 144 tiles. American players build hands from the NMJL’s yearly card; Chinese players build whatever patterns they like. American games include the Charleston exchange; Chinese games don’t. Their scoring systems barely overlap.
People ask this constantly — both games share a name and a tile set, then split into genuinely different games.
What are the biggest differences?
- Tile count. American sets run 152 tiles: the standard 144 plus 8 jokers that act as wild cards. Chinese mahjong has no jokers and plays 144 tiles, flowers included.
- How you build a hand. Americans follow the NMJL card, which lists every legal hand. Chinese players build any pattern they like — and the patterns change from city to city.
- The Charleston. American games start with a choreographed tile pass — three left, three right, then an optional exchange. Chinese mahjong doesn’t.
- Scoring. American games pay from the card’s standardized chart. Chinese scoring runs on fan, with rules that vary by region.
Which version should you learn first?

Either way, the fundamentals transfer. Set-building, draw and discard, reading the table — same bones. Pick one, learn it properly, and the other comes faster.
