Chinese vs American vs Riichi Mahjong

Updated Wind & Honour Editorial Team

Mahjong is not one universal ruleset. Chinese regional forms, American Mah Jongg and Japanese Riichi share recognisable tile families, but they can differ in equipment, calls, legal hands, scoring and table procedure.

The practical lesson is simple: choose the game first, then choose the set and learning material that support it.

This comparison is a route map, not a substitute for a complete rulebook. “Chinese-style” covers several regional systems; American organisations publish their own materials; and Riichi competition bodies define detailed procedures. A local club may use a named variation, so ask before assuming that a familiar term has exactly the same effect.

Use this page to choose between the three broad learning routes. For the decisions you face at an actual table, continue with one of these focused guides:

Choose the specific rules before following a lesson. A shared tile design does not make the procedures interchangeable.

Chinese-style Mahjong

“Chinese-style” is a broad product and learning description, not the name of one complete rulebook. Many Chinese forms use the three numbered suits, Winds and Dragons. Many physical sets also contain Flowers and Seasons, giving a 144-tile set.

Regional rules can differ over the treatment of bonus tiles, minimum scores, special hands, dealer rotation and payments. A beginner guide should therefore say which framework it introduces and point players back to an agreed rule reference for scoring.

Wind & Honour uses “Chinese-style” to distinguish The Club Set from American Mah Jongg equipment. It does not claim that every Chinese table plays the same rules.

The 136-tile core of three suits, Winds and Dragons is a useful point of recognition. Many Chinese-style physical sets add Flowers and Seasons to reach 144 tiles. Whether all of those tiles enter play, how bonus tiles are replaced and which hands score depend on the chosen system.

Calls are often translated into English as chow, pung and kong, although spellings vary. That shared vocabulary can help a beginner, but priority rules, minimum scores and payments must still be learned from the actual rulebook. Family and social tables may also follow practices passed down within the group.

American Mah Jongg

American Mah Jongg has a distinct organised format. The National Mah Jongg League publishes an annual card of standard hands and rules. Its official overview also identifies jokers and the Charleston — a starting exchange of tiles — as characteristic differences.

Because the hand card changes annually, players need the current card rather than only a generic list of winning shapes. American sets are commonly sold with the tile mix and racks expected by that community.

A Chinese-style 144-tile set should not be marketed as American-compatible without checking the exact tile breakdown and equipment requirements.

American play is not defined by adding jokers to an otherwise unchanged Chinese ruleset. The annual card identifies the hands being pursued, and the Charleston creates an opening passing procedure. Racks and pushers are commonly used at American tables. A new player should obtain the current card and learn from material written for that season and organisation.

Riichi Mahjong

Riichi is a Japanese form. The European Mahjong Association’s competition rules describe 34 basic tile types with four copies of each, making a 136-tile set. Flowers, seasons and jokers are not used in those rules.

Riichi has its own scoring vocabulary and procedures, including the declaration from which the game takes its name. Japanese sets may include red fives; a specific rule code decides whether they replace ordinary fives in play.

Riichi needs a recognised yaku as well as a permitted hand structure and winning procedure. Dora adds bonus value but does not replace that yaku. Declaring riichi is one route to a yaku, not a requirement for every win. A furiten player cannot claim ron, even when the hand has a yaku; a valid self-drawn win remains possible.

Follow our Riichi Mahjong rules for beginners for a worked hand using the EMA 2025 code and its official annotations. That version does not use red fives. Wall procedure includes a dead wall and replacement draws; keep those procedures separate from lessons for other games.

The European Mahjong Association and World Riichi Championship publish detailed competition rules. Those sources are a better foundation than a short comparison when preparing to enter organised play.

A compact comparison

Question Chinese-style American Riichi
One universal ruleset? No; several regional systems Organised around an annual card and rules Defined rule codes
Common physical count Often 144; check breakdown Check jokers and equipment 136 core tiles
Flowers/seasons Common in many sets; use varies Check current requirements Not used in EMA rules
Jokers Depends on regional game/set Characteristic of American play Not used in EMA rules

The opening of a hand

In many forms, four players build walls and use an agreed procedure to choose the dealer, break the wall and deal. The details are not interchangeable. Wall length changes with the number of live tiles, bonus-tile replacement can change the deal, and Riichi defines a dead wall for particular draws.

American Mah Jongg adds the Charleston passing procedure described by the National Mah Jongg League. That is a structural part of its opening, not an optional translation of an ordinary discard. A beginner moving between forms should relearn the setup sequence before focusing on strategy.

Hands, wins and scoring

A familiar-looking shape does not establish a legal win across all Mahjong versions. Four sets and a pair is a basic structure in several forms; special hands and winning restrictions depend on the chosen system.

  • MCR, one named Chinese competition system: check an allowed structure, at least eight scoring points excluding flowers, and a permitted way of obtaining the final tile. Other Chinese regional systems may use different requirements.
  • Riichi: check the hand structure, a recognised yaku and the other winning restrictions in the chosen rules. MCR's eight-point threshold is not the Riichi requirement.
  • American Mah Jongg under NMJL rules: follow the current annual card and its rules for the hand being built.

Our MCR winning-hand guide works through one complete example. Its structure and scoring explanation are specific to the MCR reference hosted by EMA, not a universal definition of Chinese Mahjong.

A learning path for each form

For a named Chinese system, begin with the tile families and turn rhythm, then learn its particular bonus-tile handling, legal hands and payments. If a family or club is teaching, ask them to name the system or provide the reference they expect.

For American Mah Jongg, obtain the current card, identify the joker rules and learn the Charleston with a teacher or current guide. An old card can still illustrate the format but should not be presented as the current season’s standard hands.

For Riichi, start with a thirteen-tile wait and a fourteen-tile completed hand, then practise yaku, ron, tsumo and furiten together. Use the same full code for wall setup, calls and scoring. Our example follows EMA; a platform or club may choose another version.

Questions to ask a club or teacher

  1. What is the full name or link for the rules you use?
  2. How many tiles enter the live wall?
  3. Are Flowers, Seasons, jokers or red fives used?
  4. Which calls are allowed, and how are competing calls prioritised?
  5. Is a minimum score, yaku or current hand card required to win?
  6. Which accessories should a learner bring?

Which set should you choose?

Ask the group what they plan to play. If the answer is vague, decide on one ruleset before purchasing. Then compare the complete tile breakdown, any annual card or accessories required, the terminology used in the instructions and whether the product page names the intended Mahjong style clearly.

The Club Set is sold as a Chinese-style 144-tile set and not as an American Mah Jongg set. The Table Mat is a playing surface and does not determine the ruleset.

If you have not chosen a game yet, read a complete source for each form and watch or attend a teaching session before buying. If you already have a regular group, their named rules should control the decision. The most useful set is the one whose verified contents match the game actually played.

Match a listing to your table

A product name that includes American, travel or Mahjong is only a starting point. Match the exact tile faces and breakdown to your group’s rules, and check racks, cards and other equipment separately. A decorative design can change how familiar symbols are drawn, so examine the complete tile-family image before choosing.

Common questions

Can I mix rules from different versions?

For a first game, agree on one complete reference. Mixing a hand requirement from one version with scoring or setup from another can make the game unclear.

Does a shop category guarantee rules compatibility?

No. A general Mahjong collection can contain different products. Check the exact tile breakdown and your table's requirements.
