The short answer: American mahjong is a 4-player game that grew out of Chinese mahjong in the 1920s, spread largely by American Jewish communities. It uses 152 tiles — the standard 144 plus 8 jokers — and every hand is built from the National Mah Jongg League’s yearly rule card. Expect the Charleston, fast play, and loud conversation.
If your grandma had a mahjong night, this is the game she played. It’s not tile matching on a screen — it’s a social table game for four people, found at community centers and family game rooms.
What makes American mahjong different from Chinese mahjong?
- 152 tiles instead of 144. You get the standard set plus 8 jokers, and jokers are wild — they stand in for any tile.
- The yearly NMJL card. The National Mah Jongg League prints a new card each year listing every legal hand, so everyone builds from the same list.
- The Charleston. At game start you pass tiles around — three left, three right, then an optional final exchange — to shake up your hand.
- It’s social first. Four players, table talk, and winning is nice but the evening is the point.
How does a hand of American mahjong play out?
Each player starts with 13 tiles, draws one, discards one. Your goal is to complete a hand from the card — three sets plus a pair, four of a kind plus a pair, that kind of thing. Match one and you win.
Most players spend their first games just learning to read the card. That’s normal — half the fun is figuring out this year’s hands together.

Related Questions
Is American mahjong the same as Chinese mahjong?
No. They share tiles and the idea of building sets, but American mahjong adds jokers, a yearly card, and the Charleston. Chinese mahjong has none of those.
What is the Charleston in American mahjong?
A passing ritual at game start: three passes left, three right, then one optional more. The goal: dump tiles that don’t fit your target hand.
Do I need the NMJL card to play?
At a real table, yes — the card defines every legal hand. Clubs sell the current one, and the whole table just has to agree on which card you’re using.
Can you learn American mahjong online?
You can learn hand-building online, but the card and the Charleston are easier in person. Mahjong players love teaching, so ask around.
