American Mahjong vs. Chinese Mahjong
American Mahjong and Chinese Mahjong are related tile games, but their rules are not interchangeable. American Mahjong commonly refers to a distinct regional form; NMJL-style play uses a changing annual card of winning hands and includes the Charleston. “Chinese Mahjong” can mean several regional forms, so there is no single Chinese ruleset to compare against in every detail.
The most useful comparison is therefore between American Mahjong as played under a specified ruleset and a named Chinese regional variant. This page describes broad distinctions without treating any one version as universal. For an overview of American play, visit the American Mahjong guide.

|---|---|---|
| Winning-hand reference | Current annual card lists eligible patterns | Depends on the regional ruleset; there is not one universal Chinese hand list |
| Opening exchange | Charleston is commonly part of NMJL-style play | Procedures differ by variant; do not assume the American Charleston |

| Calls and scoring | Governed by the current card and associated rules | Vary significantly among regional forms |
| Best source for a specific ruling | Current card and rules used by the table | The named variant’s current rules |

1. How players identify a winning hand
In NMJL-style American Mahjong, players work toward one of the patterns printed on the current annual card. Those patterns and their requirements change over time. Players keep the current card available and verify each hand against it.
Chinese Mahjong is not one single ruleset. Different regional systems define winning hands, scoring, and special patterns in different ways. Some use familiar groups such as pairs or sets, but overlapping group names do not make the whole hand system identical.
2. The Charleston
The Charleston is a distinctive opening tile-passing phase in NMJL-style American Mahjong. Its procedure follows the applicable rules. It is not a universal step in every Mahjong game, and it should not be assumed when learning another variant.

3. Tile sets and jokers
A set should match the rules being played. American Mahjong sets commonly include components used by the American card and rules, including jokers where required. Other forms may use different tile counts, special tiles, or substitution rules. Even where two sets look similar, verify their actual contents before using them for a specific game.
In American Mahjong, joker use is restricted by the card and rules; it is not a universal substitute for any tile. Other variants may treat special tiles differently or not use American-style jokers. See American Mahjong tiles and how to choose a set.
4. Calls, turns, and scoring
Discard claims, turn order, scoring, and round-ending procedures differ by variant. The same term can be used in different games with different consequences. Learn the named ruleset rather than relying on a generic Mahjong explanation.
For American game flow, use How to Play American Mahjong and the dedicated rules page. Those resources do not define Chinese regional rules.
Which version should I learn?
Choose based on the people you plan to play with, the rules used by your local group, or the kind of game you want to explore. Ask what variant a club or host plays before buying a set or studying rules. If you are joining an American table, start with the beginner’s guide and use the card specified by that group.
Frequently asked questions
It is a regional form within the broader history and family of Mahjong games, but it has distinct conventions. Modern comparisons should name the specific ruleset rather than assume one universal “Chinese Mahjong.”
Sometimes a set may be usable across more than one game, but compatibility depends on its exact tiles and accessories and the rules of both variants. Check the contents before playing.
Tile families and special pieces can overlap, but sets and rules differ. Confirm the required components for the particular variant.
The American Charleston is associated with NMJL-style American play. Do not assume it is part of a Chinese regional ruleset; check that variant’s instructions.
