One Game, Three Flavors
Mahjong is not a single game with a single rulebook. It is a family of games that share the same tiles and the same basic rhythm — draw one, discard one, build a hand — but diverge sharply in how you win.
The three biggest branches are Chinese Mahjong, American Mah Jongg, and Japanese Riichi Mahjong. They are popular in different places, played by different communities, and suited to different kinds of players. Here is how to tell them apart.
Chinese Mahjong
Chinese Mahjong is the original and the most flexible of the three. It uses a standard 144-tile set and the classic winning shape: four melds and one pair.
The rules are relatively open. You build sequences and triplets, claim discards with chi, pong, and kong, and win by completing your hand. Scoring varies by region — Cantonese, Hong Kong, and Chinese Official all have their own tables — but the foundation stays the same.
For most newcomers, Chinese Mahjong is the best first stop. There are no jokers and no required card, just a clean set of rules that teach you the game's core. Our beginner's guide and free Chinese Mahjong course teach it from scratch.
American Mah Jongg
American Mah Jongg is the dominant tabletop variant in the United States. It grew out of the Mahjong craze of the 1920s and was standardized by the National Mah Jongg League, which still publishes an annual card of official hands.
It changes three things from the Chinese game:
- 152 tiles — the standard set plus eight jokers.
- The NMJL card — you must match one of the specific hands printed on the current year's card.
- The Charleston — a pre-game exchange where players pass tiles right, across, and left.
Because the card changes every year, American Mah Jongg rewards players who enjoy studying hands and following a precise target. It is also deeply social, with a strong club culture. See our American Mahjong rules guide for the full picture.
Japanese Riichi Mahjong
Riichi Mahjong is the competitive, fast-moving version that dominates online play. It uses 136 tiles (no flowers or seasons) and is known for two distinctive features:
- Riichi — when your hand is one tile away from winning, you can declare riichi, betting a stick of points and freezing your hand in exchange for bonus scoring.
- Dora — bonus tiles revealed during play that add value to your hand, introduced through the dead wall.
Riichi also has a strict requirement that your winning hand must contain at least one yaku, or scoring pattern. That list is long — everything from a simple all-simples hand to rare and famous patterns — which is why Riichi has the steepest learning curve of the three but also the deepest competitive scene.

Which Should You Learn?
The right choice depends on your situation:
- Learn Chinese Mahjong first if you want the cleanest introduction to the game's core. It is the best foundation, and everything else builds on it.
- Learn American Mah Jongg if you live in the U.S. and want to join an in-person club. It is what most American tables play, and the club scene is thriving.
- Learn Riichi if you want to play online, compete, or love deep strategy. It is the most complex but the most rewarding for competitive players.
You do not have to pick one forever. Many players start with Chinese Mahjong, then learn American Mah Jongg to join a local club, or dive into Riichi for online play. The tiles and the draw-and-discard rhythm transfer across all three.

Frequently Asked Questions
- What is the difference between Riichi, American, and Chinese Mahjong?
- Chinese Mahjong uses 144 tiles and a four-melds-plus-a-pair hand. American Mah Jongg uses 152 tiles with jokers, requires matching a yearly NMJL card, and starts with the Charleston. Japanese Riichi uses 136 tiles, adds a riichi declaration and dora bonus tiles, and requires a valid scoring hand called a yaku.
- Which Mahjong is easiest for beginners?
- Chinese Mahjong is usually the easiest entry point because its core hand is simple and there are no jokers or a required card. American Mah Jongg is also beginner-friendly in clubs because the NMJL card gives you a concrete target. Riichi is the most complex to learn because of its long list of scoring hands.
- Which Mahjong is most popular online?
- Japanese Riichi is the most popular online, especially in competitive play, anime communities, and apps like Mahjong Soul. American Mah Jongg is the most popular in-person tabletop variant in the United States.
- Can I use the same tile set for all three variants?
- Mostly. A standard 144-tile Chinese set works for Chinese and Hong Kong play. You can add jokers to make an American set, and you can remove flowers and seasons to play Riichi with 136 tiles.
- Should I learn Chinese Mahjong before American or Riichi?
- It helps. The draw-and-discard rhythm and the idea of building sets and a pair are shared across all three, so learning Chinese Mahjong first gives you a transferable foundation.
