American vs Chinese Mahjong

A reader lands on this page for one of two reasons. Either you're trying to decide which version to learn, or you're trying to figure out whether the set you have can play the version your friend plays. Both are real questions with practical answers.

By the end of this page, you'll know exactly what separates American and Chinese mahjong, which equipment serves which game, whether you can play both, and which one is probably the right starting point for you. Use the quick-comparison table for the fast answer; read on for the depth.

Mahjong is a family of related games, not a single game with regional variations. American Mahjong and Chinese Mahjong share the same broad lineage — both descend from late-19th-century Chinese tile games — but they have diverged enough over the last hundred years that they now play as fundamentally different experiences.

Saying “let's play mahjong” without specifying which version is like saying “let's play football” without specifying American football or soccer. The participants might use the same word, but they're committing to very different evenings.

Most importantly: a typical Chinese mahjong set cannot play American Mahjong. And conversely, an American set is awkward (though usable) for Chinese mahjong. The equipment is partly different, the rules are substantially different, and the community is entirely different.

The fast answer for readers who just need the gist.

This is the single most important difference between the two games. American Mahjong uses an annual Card published each spring by the National Mah Jongg League. The Card lists roughly 70 specific winning hand patterns — you must build your tiles to match one of those printed patterns exactly. The Card changes every year on April 1.

Chinese Mahjong has no annual card. Players freely construct winning hands of “4 sets + 1 pair” using any combination of triplets, quads, and sequences, with scoring based on the hand's features (called faan or fan). The hand catalog is large but stable.

What this means in practice: American players study the new Card every spring and memorize section by section. Chinese players learn the broad faan catalog once and apply it for life. Strategy in American mahjong is largely about choosing which Card hand to pursue. Strategy in Chinese mahjong is about constructing a high-scoring hand from whatever the tiles give you.

American sets contain 152 tiles — the standard 144 plus 8 joker tiles. Jokers are wild tiles that can substitute for any natural tile within a set of three or more, but never in a pair. They are a unique American innovation, added by the NMJL in the early 1960s.

Chinese sets contain 144 tiles with no jokers. Every tile in the winning hand must be a natural tile (or a flower in the bonus positions).

What this means in practice: Jokers are central to American strategy — managing them, hoarding them, and “robbing” them from opponents. Without jokers, Chinese mahjong is purer in a sense: every tile must do its own work.

American Mahjong opens every hand with a Charleston — a ritualized exchange of tiles in a fixed sequence: three tiles right, three tiles across, three tiles left, optionally repeating in reverse. The mnemonic is R.O.L.L.O.R. — Right, Over, Left, Left, Over, Right. Jokers may never be passed.

Chinese Mahjong has no equivalent. Play begins directly after the deal; the hand you're dealt is the hand you start playing.

What this means in practice: The Charleston is one of the most beloved rituals in American mahjong and a major part of its social pleasure. Chinese mahjong begins faster but offers less hand-shaping before play.

American Mahjong does not use sequences (chow) in winning hands. Hand patterns are built entirely from triplets (pung), quads (kong), quints (5 of a kind, only possible with jokers), pairs, and singles. The “chow” call is simply not part of the game.

Chinese Mahjong treats sequences as one of the three basic set types. Most Chinese hands contain at least one chow (a run of three consecutive same-suit tiles). The chow call is standard.

What this means in practice: American players never call “chii” or build runs. Chinese players use sequences constantly; a hand of all-sequences (called all chows) is a common and well-scoring pattern.

American Mahjong allows three types of calls — pung (three of a kind), kong (four of a kind), and quint (five of a kind, requires jokers). You cannot call a sequence.

Chinese Mahjong allows chow (sequence, only from the player on your left), pung, and kong. Sequences are essential.

In both games, called tiles must be displayed face-up as exposures. In American mahjong, exposures must be consistent with at least one Card hand — meaning calls effectively announce your strategy to the table. In Chinese mahjong, exposures are less informative because hands can be more freely constructed.

American Mahjong uses a fixed-points-per-hand system. Each hand on the Card has a printed value — typically 25 to 75 points. Modifiers include: self-drawn win (doubles the value); jokerless win (doubles the value); concealed hand (printed at the higher concealed value on the Card). The discarder of the winning tile (if Mah Jongg is called on a discard) typically pays double.

Chinese Mahjong uses a faan-doubling system. Each feature of a winning hand adds a faan value, and the total faan determines the score by doubling (2 faan = 4 base units, 3 faan = 8, 6 faan = 64, etc.). Most Hong Kong-style games require a minimum of 3 faan to declare a win and cap at 13 faan (a limit hand). The discarder-pays-all rule in Hong Kong Old Style is particularly distinctive: the player who discards the winning tile pays the full score; only on a self-draw do all three opponents pay.

What this means in practice: American scoring is simple once you know the Card — values are right there in print. Chinese scoring rewards understanding which features stack, and is more strategically complex over time.

American Mahjong is a primarily American game, codified in 1937 by Dorothy Meyerson and Viola Cecil at a meeting at the Essex House hotel in New York City. The NMJL has more than 350,000 active members. American mahjong has particularly deep roots in Jewish American culture — many players inherited the game matrilineally across three or four generations. Tuesday-afternoon mahjong groups have run for forty or fifty years.

Chinese Mahjong is the older form and the more globally played one. It is the mahjong of Chinese families across the Sinosphere, of Lunar New Year gatherings, of the licensed parlors of Hong Kong, and of the kitchen-table tournaments that run from after dinner well into the morning. Tens of millions of players worldwide play some form of Chinese mahjong.

Both games share the basic tile families, but with important differences in size, count, and inclusion.

An American set is larger and more legible — designed for easy reading from a rack and accommodating older eyes. A Chinese set is more agile in hand — easier to shuffle and stack, more suited to fast-paced play.

American racks are sized for larger tiles; Chinese tiles fit poorly in American racks and vice versa. The flowers are typically numbered in American sets (F1–F8) for matching to specific Card hands, where they're typically labeled with their Chinese meanings (plum, orchid, etc.) in Chinese sets.

Two very different approaches to determining a winner's score.

Look up the hand on the Card. Each hand has a printed point value, usually 25–75.

Apply modifiers: Self-drawn (Mah Jongg from the wall) — typically double the value. Jokerless (no jokers in the winning hand) — typically double the value. Concealed (no calls made) — already printed at higher value on the Card.

Identify who pays. If won on a discard, the discarder pays the full value to the winner. If won by self-draw, all three opponents pay the full value.

Count the faan. Each feature of the winning hand adds to the faan total: Dragon pung: 1 faan. Seat or round-wind pung: 1 faan. All chows: 1 faan. All pungs: 3 faan. Half flush: 3 faan. Full flush: 6 faan. Limit hands (Big Three Dragons, Four Winds, etc.): 13 faan.

Determine the score. Scores double per faan, typically capped at a house limit (often 8, 10, or 13 faan).

Identify who pays. Won on a discard: the discarder pays the full score to the winner alone. Won by self-draw: all three opponents pay equally. This discarder-pays-all rule on discard wins is uniquely punishing in HKOS — every discard is a small wager.

Understanding why these games diverged requires understanding where each came from.

Mahjong was born in coastal China in the mid-to-late 19th century. The earliest surviving sets date to the 1870s, made in Ningbo, Shanghai, and Fuzhou. A Qing official named Chen Yumen (1817–1878) is traditionally credited with refining the game into something close to its modern tile form.

Through the late Qing and early Republican periods (roughly 1880–1949), Chinese mahjong became the social glue of Chinese family life — particularly Cantonese family life. It survived the communist suppression of the Cultural Revolution (1966–1976) by being played in secret, was legalized again in 1985, and was formally recognized as a sport by China's General Administration of Sport in 1998.

Chinese mahjong today is the form played by tens of millions of people across the Sinosphere — in Hong Kong, Macau, mainland China, Taiwan (in a 16-tile variant), and the worldwide Chinese diaspora. It is the mahjong of Lunar New Year, of family weddings, of the licensed parlors of Hong Kong, and of the kitchen-table tournaments that run from after dinner well into the morning.

American mahjong has a different story, one specific to the United States. In 1920, an Indiana-born Standard Oil representative named Joseph Park Babcock sat down at a mahjong table in Shanghai, learned the game from his Chinese colleagues, and brought it back to America. He simplified the rules, added Arabic numerals to the tiles, trademarked the spelling “Mah-Jongg” with two G's, and ignited a national craze.

By 1923, mahjong was the dominant parlor game in America. Abercrombie & Fitch was selling 170 tons of Chinese mahjong sets imported by Babcock himself. Saturday Evening Post covers depicted women at mahjong tables. Gershwin wrote songs about it. The Ziegfeld Follies built numbers around it.

By the late 1930s, the rules had splintered. In 1937, two New York women — Dorothy Meyerson and Viola Cecil, both Jewish American — convened a meeting at the Essex House hotel on Central Park South to standardize American play. They expected one hundred attendees. Nearly four hundred showed up. That meeting founded the National Mah Jongg League, and their innovation — the annual Card — gave American mahjong the distinctive structure it has today.

Through the 1940s and beyond, American mahjong became deeply intertwined with Jewish American culture — so much so that many players genuinely believed it was an Old Country tradition. The Card became a generational ritual: ordered every spring, carried in wallets, taught from mother to daughter to granddaughter.

Today the NMJL has more than 350,000 members. Tuesday-afternoon mahjong groups have run for forty or fifty years in suburban living rooms, retirement communities, and JCCs across the country.

Yes — many people do. But you'll need to learn each game separately.

The good news: Both games share the same basic vocabulary (suits, honors, winning condition of “4 sets + 1 pair,” and the rhythm of draw-and-discard). Once you know one, the basic structure of the other is recognizable. The two communities don't compete — most players who learn both report that the games scratch different itches.

The challenges: The rules are different enough that you'll forget one when you focus on the other. The equipment is partly incompatible (sets, racks, tile sizes). The communities are largely separate — most American mahjong groups don't play Chinese, and vice versa. The strategic instincts differ. American mahjong rewards card-knowledge and joker management; Chinese mahjong rewards faan accumulation and concealed-hand strategy.

Most cross-tradition players settle into a primary game and play the other occasionally with different friend groups.

A practical question with an honest answer: it depends on who's around you.

There's no wrong answer. The best mahjong is the mahjong played at the table you'll actually sit at.

The set you buy must match the game you play. Quick guide:

A 144-tile Chinese set is the most flexible single purchase — it plays Hong Kong, MCR, Chinese Classical, Taiwanese (with appropriate racks), and Riichi (by removing the flowers and seasons). It does not play American Mahjong.

If you want to play both, plan on owning two sets.

If you'd like to go deeper into either tradition:

Neither American Mahjong nor Chinese Mahjong is the “real” mahjong. Both are real. Both are alive. Both are deeply loved by their communities. The Card and the Charleston are no less authentic for being newer than the original Chinese game; the faan system and the Lunar New Year family table are no less alive for being older than the American version.

What matters is which game you sit down to play, with whom, and for how long.

Find the table that's open to you. Learn the version they play. Then play it for the next forty years.
