If you're new to mahjong and trying to figure out which version to learn — or you grew up playing one and want to understand the other — the difference between American and Chinese mahjong is bigger than most people expect. They share the same beautiful tiles and the same basic spirit of the game, but the rules diverged so much in the twentieth century that they really play like two different games. This guide lays them side by side so you can see exactly how they differ and pick the one that fits you.
What this guide covers
A quick history of how they diverged
Mahjong was developed in China in the mid-1800s and remained largely a Chinese game until the 1920s, when it spread to the West. American players adapted the game heavily during that decade — most importantly, the National Mah Jongg League (NMJL) was founded in 1937 and began publishing a yearly card of legal hands. That card became the defining feature of the American game and is the reason the two versions feel so different today. Chinese Mahjong, meanwhile, kept evolving regionally — Hong Kong style, Cantonese, Sichuan, Taiwanese, and many more variants exist, each with their own twists.
The tiles: what's in each set
Both games use the same basic categories of tile — three suits (dots, bams, craks), winds, dragons, flowers — but the totals and extras differ:
- Chinese set: 144 tiles. 36 dots, 36 bams, 36 craks, 16 winds, 12 dragons, 8 flowers/seasons. No jokers. Most Chinese sets don't have English letters or Arabic numerals on the tiles.
- American set: 166 tiles. Same suits, winds, and dragons, but with eight jokers, more flowers, and a few blank spares. American tiles almost always have English letters and Arabic numerals printed in the corner, which makes them much easier to learn on.
American sets also typically include four racks (angled trays that hold your tiles upright), often combined with pushers. Chinese play doesn't traditionally use racks — players hold their tiles standing on the table in front of them.
The goal: how you win
This is the biggest single difference between the two games.
Chinese: four sets and a pair
In standard Chinese Mahjong, a winning hand is built from a classic structure: four sets plus a pair. A "set" is either three identical tiles (a pung), three consecutive numbers in the same suit (a chow), or four identical tiles (a kong). You're free to assemble whichever combination of these gets you to a complete hand. There's enormous flexibility — many regional variants add bonus patterns and special hands — but the core is always those four-sets-and-a-pair.
American: match a printed hand on the card
American Mahjong throws that structure out and replaces it with a list. Each spring, the NMJL publishes a card listing roughly 70 specific winning hands for that year. You can only win with a hand that matches one of those exact patterns. No chows are used; instead, hands are built from very specific combinations of pairs, pungs, kongs, and (occasionally) quints, often with restrictions on suits and colors. The card changes every year, so even experienced players relearn their target hands each spring.
Trade-off: American Mahjong removes the need to recognize valid hand structures yourself — the card tells you — but adds the task of reading and choosing among many specific patterns. (We have a dedicated guide on how to read the NMJL card.)
How play differs at the table
The Charleston (American only)
American Mahjong begins each hand with a structured tile exchange called the Charleston: players pass three tiles at a time — right, across, left — to improve their starting hands before regular play. There's nothing like it in Chinese Mahjong. (See our step-by-step Charleston guide.)
Jokers (American only)
The eight jokers in an American set are wildcards that can stand in for any tile inside a pung, kong, or quint (never in a pair or single). They make the American game more forgiving and add a whole layer of strategy — collecting jokers, swapping for them off the table, and choosing jokerless hands for bonus value. Chinese Mahjong has no jokers at all.
Chows vs. no chows
In Chinese play, calling a "chow" — three consecutive numbers in the same suit, like 4-5-6 of bams — is a fundamental move. In American Mahjong, chows simply don't exist; the card never calls for them. American players think exclusively in groups of identical tiles (pairs, pungs, kongs, quints).
Calling and exposing
Both games let you call a discarded tile to complete a group, but with different mechanics. Chinese Mahjong allows calling chows (only from the player on your left), pungs, and kongs. American Mahjong allows calling pungs, kongs, and quints — and exposed groups go on top of your rack for everyone to see.
Scoring
Scoring is also strikingly different. Chinese Mahjong uses point systems where you tally up fan (multipliers) and base points based on the specific patterns and conditions of your hand — flowers held, kongs declared, who dealt, and many more. Different regions have different scoring tables, and the math can be involved.
American Mahjong is much simpler: every hand on the card has a printed point value, and when you win, the other three players pay you that value (usually with a couple of common doubles for self-pick or jokerless wins). No multipliers to compute. (Full details in our scoring guide.)
Side-by-side comparison
| Feature | American Mahjong | Chinese Mahjong |
|---|---|---|
| Total tiles in set | 166 | 144 |
| Joker tiles | 8 (wildcards) | None |
| Winning hand structure | Match one of ~70 hands on the annual card | Four sets + a pair |
| Uses an official card | Yes, new card every year | No |
| Chows (3 consecutive in a suit) | Not used | Standard |
| Quints (5 identical) | Allowed on some hands | Not used |
| Tile-passing before play | Yes — the Charleston | No |
| Racks & pushers | Standard | Not traditional |
| Tiles with English/Arabic markings | Usually yes | Usually no |
| Scoring | Card prints each hand's value | Fan multipliers + base points |
| Regional variants | One unified ruleset (NMJL) | Many (HK, Cantonese, Taiwanese, etc.) |
Which should you learn?
Both games are wonderful — it really comes down to where you are and who you'll be playing with.
- Learn American Mahjong if you're in the US and have friends, family, or a local club that plays. The card removes guesswork, the tiles are easier to read, and the social American game is having a major resurgence right now.
- Learn Chinese Mahjong if you have family connections to the game, you want to play with friends from China, Hong Kong, Taiwan, or Singapore, or you enjoy a more open game where you build hands yourself rather than from a list.
- Or learn both. Once you know one, the other is mostly about new rules layered on familiar tiles. Many players enjoy both.
Frequently asked questions
What's the main difference between American and Chinese Mahjong?
American Mahjong uses an annually-changing official card of legal winning hands plus joker wildcards. Chinese Mahjong has no card and no jokers — you build hands from the classic structure of four sets plus a pair.
Can you use the same tiles for both?
Not really. American sets have 166 tiles including eight jokers and usually English letters; Chinese sets have 144 tiles and no jokers. You need a set built for the version you're playing.
Which is easier to learn?
American is generally easier for beginners because the card tells you every legal winning hand. Chinese is more open-ended but has fewer special tiles and rules to remember.
Are there other versions besides American and Chinese?
Yes — Japanese Riichi, Taiwanese 16-tile, and several regional Chinese variants are all popular. See our guide to the different types of mahjong for an overview.
