American vs Traditional Mahjong: American vs Chinese Compared

Confused by American vs traditional (Chinese) mahjong? We break down the differences in tiles, rules, jokers, scoring, and the annual NMJL card — and which set to buy.

By Wei Liang · Founder & Production Lead, Mahjong Market

Same ancestor, two very different games. American and Chinese mahjong (Chinese mahjong is what many players mean by “traditional mahjong”) share roots and a handful of mechanics, but the sets, the rules, and the way a hand is won diverge sharply. Buy the wrong one and you are stuck with tiles that cannot be used for the game your group actually plays. Here is the practical breakdown — and which one to buy.

A short history: how American mahjong came to be

Mahjong originated in China in the mid-1800s, likely in the Shanghai region, and was played with 144 tiles. In the 1920s, an American businessman named Joseph Babcock began importing mahjong sets to the United States and published simplified English rules. The game became a national craze — so popular that it sparked a shortage of bone and bamboo.

Over the following decades, American players modified the game. In 1937, a group of players formed the National Mah Jongg League (NMJL) to standardize the rules, publish an annual card of legal winning hands, and raise money for charity. The NMJL added jokers and a Charleston tile-passing phase, and increased the tile count to 166. The result is the game Americans play today: a distinctly American version that shares roots with Chinese mahjong but has evolved into something its own.

Chinese mahjong, meanwhile, continued to develop regionally, producing Cantonese, Shanghainese, Taiwanese, and other variants — each with its own scoring conventions and house rules.

Tile counts and contents

Feature	American Mahjong	Chinese Mahjong
Total tiles	166	144
Jokers	8 (wild)	None
Flowers/Seasons	Included	Included
Labeling	English letters & numbers	Often unmarked symbols
Required card	Annual NMJL card	None

The single biggest practical difference is the joker. American mahjong uses eight wild joker tiles that can stand in for almost any tile, which dramatically changes strategy. Chinese mahjong has no jokers (though some modern Chinese sets include a few blank “joker” tiles that are not used in traditional play).

Why American needs more tiles

The extra 22 tiles in an American set come from the 8 jokers plus additional flower, season, and duplicate tiles that the NMJL’s specific hands require. Because the annual card includes patterns like quints (five-of-a-kind), the set needs enough copies of each suit tile to make those hands possible. A 144-tile Chinese set simply does not have the inventory.

How the game plays

• American mahjong plays to an annual National Mah Jongg League card that lists the exact legal winning hands for that year. You pick a hand from the card and build toward it. Before regular play, there is a mandatory Charleston — a three-round tile exchange between all players. Play is social, often with “card parties” and table stakes (“charity”).
• Chinese mahjong has no annual card and no Charleston. Players win by completing a standard pattern of four sets (pungs, kongs, or chows) and a pair. Scoring is based on the rarity and difficulty of the completed hand, and the rules vary between families and regions.

The Charleston and the NMJL card together are what make American mahjong feel so different from Chinese — even though the basic turn structure (draw, assess, discard) is nearly identical.

Language and learning curve

Because American tiles are labeled in English with clear suits and numbers, new U.S. players usually pick it up faster. The NMJL card gives a concrete target, so beginners are not guessing what “counts.”

Chinese mahjong requires memorizing the tile suits and characters, which takes longer for players who did not grow up with them. However, once the tiles are familiar, Chinese mahjong can feel more open-ended because you are not restricted to a printed card of hands.

Scoring systems compared

This is where the two versions diverge sharply:

American scoring

American mahjong uses flat per-hand values printed on the NMJL card. Each winning hand is worth a set amount — commonly 25¢, 50¢, or more for difficult hands. Every player pays the winner, with bonuses for self-drawn wins and penalties for the player who discarded the winning tile. The system is simple, fast, and designed for friendly low-stakes play. You can learn it in five minutes.

Chinese scoring

Chinese mahjong scoring is far more granular. Points are awarded for specific tile combinations, hand patterns, and conditions (winning on a self-draw, winning on the last tile, having all-flower tiles, and dozens more). Many regional systems use a “fan” or “fu” point system that is then converted into a payment multiplier. A single hand can be worth anywhere from a tiny base score to a massive payout, depending on how rare the pattern is.

Learning Chinese scoring takes time — new players often keep a cheat sheet for the first few months. Some groups simplify it by agreeing on a flat per-win payment, but that strips out much of the strategy.

Regional variants beyond American and Chinese

Mahjong is not just two games — it is a family with many branches:

• Japanese riichi mahjong uses 136 tiles (no flowers or seasons) and features a unique “riichi” bet where a player commits to their hand for a scoring bonus. It is highly competitive and has a large organized-tournament scene.
• Taiwanese (16-tile) mahjong gives each player 16 tiles instead of 13, making for larger hands and longer games. It is popular in Taiwan and among overseas Taiwanese communities.
• Hong Kong / Cantonese mahjong is probably the most common Chinese style played in the West. It uses 144 tiles and a moderate scoring system.
• Singapore and Malaysian mahjong add animal tiles (cat, rat, rooster, centipede) and have distinctive scoring bonuses.

American mahjong stands apart from all of these because of its annual card, jokers, and Charleston — features none of the Asian variants share.

Equipment differences in depth

Because American mahjong uses more tiles and an annual card, the equipment needs are different:

• Tile count: 166 (American) vs 144 (Chinese) vs 136 (Japanese riichi).
• Jokers: Only American sets include the 8 printed joker tiles. If a listing does not clearly show jokers, it is not an American set.
• Racks and pushers: American mahjong almost always uses racks to hold tiles upright and pushers to build and break the wall. Chinese mahjong is often played flat on the table without racks, though some players use them for convenience.
• Table size: American sets with racks and pushers need a slightly larger playing surface. A standard 30-inch square card table works, but a dedicated mahjong mat on a larger table is more comfortable.
• Tile size and weight: American tiles tend to be slightly larger and heavier to accommodate the English labeling. This makes them easier to read but heavier to carry — something to consider for travel or for players with hand mobility issues.

Social and cultural differences

The “feel” of the two games is different:

• American mahjong is overwhelmingly social and community-oriented. It is played in living rooms, community centers, country clubs, and synagogues. The NMJL was founded partly as a fundraising organization, and many American groups play for charity. Game nights are as much about conversation and snacks as they are about the tiles.
• Chinese mahjong tends to be more competitive and skill-oriented. While it is absolutely social — often played at family gatherings — the emphasis is on reading opponents, calculating odds, and mastering a complex scoring system. Competitive Chinese mahjong tournaments are common in Asia.

Neither approach is better; they just serve different moods. American mahjong is a wonderful excuse to gather weekly with friends; Chinese mahjong is a deep strategic hobby you can spend a lifetime mastering.

Which set should you buy?

Buy an American mahjong set if:

• You are in the U.S. and playing with friends/family who use the NMJL card.
• You want English-labeled tiles and a clear goal each game.
• You plan to join a local American mahjong group or community center.

Consider a Chinese mahjong set if:

• You specifically want to play traditional Cantonese, Taiwanese, or Japanese (riichi) styles.
• You already know those rules and want an authentic 144-tile set.

Don’t mix them

A common mistake is buying a beautiful 144-tile Chinese set and expecting to play American rules. You will be missing the jokers and the right tile counts. For American play, get a proper 166-tile American set.

So which one?

Both are wonderful games. But for most U.S. buyers, American mahjong is the more accessible, social, and widely played choice — and it is what our whole shop is built around. Pair your set with a quiet mat and pushers and you are ready for game night.
