American Mahjong vs Chinese Mahjong: What's Different?
Same tiles, different game. American mahjong is played from a card published fresh every year, uses jokers, and starts with a round of passing called the Charleston. Chinese mahjong has none of those three things.
That sounds like a small list. It changes almost everything about how a hand feels to play.
The short version: in American mahjong you're hunting for one specific hand off a printed card, and you either match it exactly or you don't win. In Chinese mahjong there's no card. You build any hand that fits the structure, and the structure has stayed put for a very long time. Everything below follows from that one split.
Do they use the same tiles?
Mostly, yes. Both games use three suits, bams and craks and dots, numbered one through nine, plus winds and dragons. Set them side by side and you'd have trouble telling them apart from across a room.
The difference is what gets added. A standard modern American set has 152 tiles, including eight jokers. A standard modern Chinese set has 144, and no jokers whatsoever. Tom Sloper, who has been keeping the reference photos of this stuff online since roughly the dawn of the internet, lays both sets out in rows and counts them for you, which is exactly the information you want at the moment you're holding a box in a store.

Can you play American mahjong with a Chinese set?
No. This is the one worth knowing before you spend any money.
A Chinese set is eight tiles short and has no jokers, so it can't run the American game. It works fine in the other direction: an American set has everything a Chinese game needs and a few extras, so you can play Chinese mahjong with it and just set the spares aside. If you think you might ever want both, buy American and you're covered.
This is also the reason a gorgeous inherited set sometimes turns out to be unplayable on Thursday. Count the tiles before you get attached. If it lands at 144, it's a Chinese set, and it's still gorgeous, and it still won't do.
What's the Charleston, and why is it only American?
At the start of every American hand, before anybody draws a single tile, all four players pass three tiles to each other in a set pattern. Right, over, left. Then optionally left, over, right. We call it ROLLOR, and once you've heard it that way you never forget the order again.
Chinese mahjong has nothing like it. You get dealt thirteen tiles, you look at them, you play. No trading, no second chance, no chorus of four women simultaneously deciding which three tiles they hate most.
The Charleston is the part beginners find most confusing and the part regulars would fight you over. It's a genuine strategic phase, and it means your opening hand isn't your destiny. For what to send away and what to hang onto, see what should you pass in the mahjong Charleston.
Why does American mahjong have jokers?
Because the American game asks you to match a specific printed hand, and that's hard. Jokers are the pressure valve.
There are eight of them in the set, and they stand in for any tile inside a group of three or more. They can't do singles and they can't do pairs, which is the rule that catches everyone at least once. Chinese mahjong has no equivalent. What you draw is what you have.
Jokers also create a whole layer of play that has no Chinese counterpart at all: you can take a joker off another player's exposure by handing over the real tile it's standing in for. That trade is a real part of American strategy, and it's covered in mahjong joker rules.
How does the winning hand work in each?
In American mahjong, the National Mah Jongg League publishes a card each spring listing the hands that count for that year. Every player at the table has the same card. You pick a line, you chase it, and the hand you turn over has to match the line exactly. The following April a new card arrives and the hands you'd finally memorized are gone.
Chinese mahjong asks for a structure instead of a specific hand: four groups plus a pair, where a group can be three of a kind, four of a kind, or a run of three consecutive tiles in one suit. Those runs are the big one. American mahjong has no runs of consecutive different tiles as a group, so a Chinese player's most natural move is a shape our game simply doesn't recognize.
Scoring splits the same way. American hands carry a point value printed right there next to them. Chinese scoring runs on tallies that stack and multiply, and the exact system varies by region and by table, which is why "Chinese mahjong" is really a family of closely related games rather than a single one.
And the mahjong on your friend's phone?
That's a different thing entirely, and it's worth being gentle about it, because roughly everyone has had this exact conversation.
The tile-matching game on the app store is a single-player puzzle. You clear a pyramid by matching identical tiles in pairs. No opponents, no card, no hands, no passing. It borrows mahjong tiles as decoration and that's the whole connection.
It also means your friend who "plays every night" has, technically, never played. Be nice. Invite her.
American vs Chinese mahjong, in one list
- Tiles. American: 152, including 8 jokers. Chinese: 144, no jokers.
- Sets. An American set plays both games. A Chinese set can't play the American one.
- The card. American hands come from an NMJL card reissued every year. Chinese has no card.
- Charleston. American only. Chinese deals and plays.
- Jokers. American only, and never in a single or a pair.
- Runs. Chinese uses runs of three consecutive tiles as a group. American doesn't.
- Scoring. American values are printed on the card. Chinese scoring varies by region.
- Players. Four in both, and American has a workable version for three players.
- Phone mahjong. A tile-matching puzzle. Lovely. Unrelated.
So which one are you learning?
If you're in the United States and somebody has invited you to a table, it's American. Almost without exception. The clubs, the community centers, the Tuesday groups, the cruise ships, the sunroom in Boca, all American.
Which is good news for a beginner, honestly. The card looks like a wall of code the first time you see it, and it's also a list of exactly what you're allowed to build. A page of specific targets is easier to aim at than an open field with instructions to make something valid. Chinese mahjong hands you more freedom than a new player usually wants.
The tiles will feel familiar to anyone who's played any version. The game on top of them is its own animal. If you're starting from zero on the American one, start here and give yourself two or three sessions before you judge how you're doing.
You'll be fine. Everyone at that table learned it the same way, and most of them are delighted somebody new is asking.
