American Mahjong vs Chinese Mahjong: What's Different?
Same tiles, very different game. The card, Jokers, the Charleston, and how you win all set American Mahjong apart from the Chinese game. Here's a clear side-by-side.
American and Chinese Mahjong share the same family of tiles, but they play like two different games. If you've played one, a few things will surprise you about the other.
The biggest difference: the card
In American Mahjong, every winning hand must match a specific hand printed on the National Mah Jongg League's annual card. You can't freestyle your own combinations — you're always building toward a hand the card allows. Chinese Mahjong has no such card; winning patterns are open-ended and scored by rules.
Jokers and Flowers
American sets include 8 Jokers, which can fill any group of three or more identical tiles — they're central to the game. Standard Chinese play doesn't use Jokers. American sets also include 8 Flowers — and unlike a Chinese set's, all eight are interchangeable. The full set is 152 tiles: 8 more than a Chinese set's 144, and those extra 8 are the Jokers.
The Charleston
Before play begins, American Mahjong has a tile-passing ritual called the Charleston — you pass tiles you don't want and receive others, improving everyone's starting hand. It's unique to the American game.
How you win and pay
American hands are scored by the point value printed next to them on the card, with the discarder paying double when someone wins off a discard. The rhythm of calling, exposing, and racing to match a card hand gives American Mahjong its distinct feel.
