Learn how to play mahjong step by step. Understand tiles, setup, gameplay, and winning hands across popular variants like American, Riichi, and Chinese mahjong.
Mahjong is a tile-based game for four players that combines skill, strategy, and a touch of luck. Originating in China during the 19th century, it has grown into one of the world's most popular tabletop games with millions of active players across dozens of countries. This guide walks you through everything you need to know — from understanding the tiles to completing your first winning hand.
Mahjong is a four-player game in which each person draws and discards tiles to build a complete winning hand. Think of it like rummy, but played with beautifully engraved tiles instead of cards. The game rewards pattern recognition, memory, and strategic decision-making.
The game's roots trace back to 1800s China, and it spread worldwide in the early 20th century. Today, major variants include Chinese Classical, Hong Kong, Riichi (Japanese), MCR (Mahjong Competition Rules), and American Mahjong. Each version has its own scoring system and special rules, but they all share the same core mechanic: draw a tile, discard a tile, and try to complete specific combinations before anyone else does.
Mahjong's enduring popularity comes from its blend of social interaction and mental challenge. A single round takes 5–15 minutes, but a full game session involves multiple rounds, giving every player chances to win. The game is easy to learn at a basic level yet offers deep strategic layers that keep experienced players engaged for decades.
Whether you call it mahjong, mahjongg, or mah-jong, the game delivers the same satisfying experience: the click of tiles, the thrill of a well-timed call, and the rush of declaring a winning hand.
A standard mahjong set contains 136 tiles divided into suits, honor tiles, and sometimes bonus tiles. American Mahjong sets contain 152 tiles because they include 8 jokers. Understanding every tile category is the essential first step before you play.
There are three suits, each numbered 1 through 9, with four identical copies of every tile:
Each suit has 36 tiles (9 values × 4 copies = 36). All three suits together total 108 tiles.
Honor tiles cannot form numerical sequences. They only form sets of identical tiles (three or four of the same tile).
| Tile Category | Count per Set | Found In |
|---|---|---|
| Bamboo (1–9, ×4 each) | 36 | All variants |
| Characters (1–9, ×4 each) | 36 | All variants |
| Dots (1–9, ×4 each) | 36 | All variants |
| Wind Tiles (4 types, ×4 each) | 16 | All variants |
| Dragon Tiles (3 types, ×4 each) | 12 | All variants |
| Flower/Season Tiles | 8 | Chinese, HK, American |
| Joker Tiles | 8 | American only |
Setting up a mahjong game involves shuffling the tiles, building the wall, breaking the wall, and dealing tiles to each player. The entire process takes about 3–5 minutes once everyone knows the steps.
Turn all tiles face-down on the table and mix them thoroughly. Players use both hands to push and swirl the tiles around. This shuffling process — sometimes called "washing" or "tossing" the tiles — is one of mahjong's most recognizable sounds.
Each player arranges tiles face-down into a row that is two tiles high. In a 136-tile game, each player builds a row of 17 stacks (34 tiles). In American Mahjong with 152 tiles, each player builds a row of 19 stacks (38 tiles). Push the four rows together to form a square — this is the "wall."
The dealer (East) is chosen by dice roll or mutual agreement. The dealer position rotates throughout the game. Being the dealer matters because East always goes first and, in some variants, receives extra points for winning.
The dealer rolls two dice. The total determines where to break the wall and begin dealing. Starting from the break point, tiles are distributed in sets of four (two stacks at a time) going counterclockwise around the table. Each player receives 13 tiles. The dealer takes one extra tile for a starting hand of 14.
Place your tiles on a rack so only you can see them. Sort them by suit and value. Look for pairs, sequences, and groups of matching tiles. Begin planning which combinations you want to complete.
Gameplay follows a simple cycle: draw one tile, then discard one tile. Each player takes turns in sequence, and the round continues until someone completes a winning hand or the wall runs out of tiles.
This cycle repeats around the table. Each turn takes only a few seconds for experienced players, though beginners should take the time they need.
You do not always have to wait for your turn. When another player discards a tile you need, you can "call" it to claim that tile. The three main calls are:
When you call a tile, you must reveal the completed set face-up on the table. This gives other players information about your hand, so calling is a strategic trade-off between speed and secrecy.
When you complete all required combinations, you declare your win by saying "Mahjong!" (or "Hu" in Chinese, "Tsumo"/"Ron" in Japanese Riichi). You reveal your full hand for all players to verify. If the hand is valid, you score points. If it is invalid, you face a penalty in most variants.
A standard winning hand contains 14 tiles arranged in four sets of three (or four) tiles plus one pair. This basic structure applies across most mahjong variants, though the specific patterns and scoring requirements vary.
4 Sets + 1 Pair = Mahjong (14 tiles)
Each "set" is one of the following:
The pair (also called "eyes") is simply two identical tiles.
For example, a valid winning hand could be:
| Variant | Winning Structure | Key Difference |
|---|---|---|
| Chinese Classical | 4 sets + 1 pair | Flexible; many valid patterns |
| Hong Kong | 4 sets + 1 pair (min 3 faan) | Minimum scoring threshold required |
| Riichi (Japanese) | 4 sets + 1 pair (min 1 han) | Must have at least 1 scoring element (yaku) |
| American (NMJL) | Matches a hand on the yearly card | Specific patterns required; card changes every April |
| MCR (Competition) | 4 sets + 1 pair (min 8 points) | 81 recognized scoring patterns |
American Mahjong stands apart because winning hands must match one of the specific patterns printed on the current NMJL card, which is published annually. Players purchase a new card each year from the National Mah Jongg League.
The six most widely played mahjong variants are American, Riichi (Japanese), Chinese Classical, Hong Kong, Taiwanese, and MCR (Competition Rules). Each variant uses the same basic tiles but applies different rules for calling, scoring, and winning.
American Mahjong is the most popular variant in the United States. It uses 152 tiles, including 8 jokers that serve as wild cards. Winning hands must match patterns on the NMJL card, which changes every April. The Charleston — a pre-game tile exchange between players — is unique to this variant. Players pass tiles to opponents in a structured sequence before gameplay begins.
Riichi Mahjong uses 136 tiles with no jokers or flower tiles. Its defining feature is the "riichi" declaration: when a player is one tile away from winning, they can declare riichi by placing a 1,000-point stick on the table. This locks their hand but increases their potential score. Scoring uses the han/fu system, where han represents scoring multipliers and fu represents base points. A minimum of 1 han (one scoring element, called a yaku) is required to win.
Chinese Classical Mahjong is the oldest widely played variant and uses relatively simple scoring. Hong Kong Mahjong evolved from it and requires a minimum of 3 faan (scoring points) to declare a win. Both variants use 136 tiles plus optional flower and season tiles (totaling 144).
MCR was standardized in 1998 by China's State Sports Commission for international tournament play. It recognizes 81 scoring patterns and requires a minimum of 8 points to win. MCR is the format used in many World Championship events and EMA-sanctioned tournaments across Europe.

New players should focus on three core strategies: keep your hand flexible, watch the discards, and avoid revealing information too early. These principles apply across every mahjong variant.
In the early rounds, hold onto tiles that work in multiple combinations. A 5 of Dots, for example, can form sequences with 3-4, 4-6, or 6-7. Edge tiles like 1 or 9 are less flexible because they only connect in one direction. Discard isolated tiles that do not connect to anything in your hand.
The tiles other players discard tell you two things: what they do not need and, by implication, what they are collecting. If you see three 8 of Bamboo tiles in the discard pool, nobody — including you — can complete a pung of 8 of Bamboo. Use this information to avoid chasing impossible combinations.
Every time you call a tile (chow, pung, or kong), you reveal part of your hand. This gives opponents clues about your strategy. In general, avoid calling unless the tile significantly accelerates your path to winning. Playing a "closed" hand (no calls) also earns bonus points in several variants, including Riichi Mahjong.
As the round progresses, pay attention to what tiles are safe to discard. If a player appears close to winning, discard tiles they have already discarded or tiles that are common in the discard pool. In Riichi Mahjong, defensive play is especially critical — dealing into another player's winning hand ("dealing in") costs you the full point value.
The best way to improve is through practice with experienced players. Consider joining a mahjong club in your area where you can learn in a friendly, low-pressure setting.
Now that you understand the fundamentals, the fastest way to improve is to play with real people. Reading about mahjong builds knowledge, but hands-on practice builds skill.

Learn how to play mahjong step by step. Understand tiles, setup, gameplay, and winning hands across popular variants like American, Riichi, and Chinese mahjong.
A standard Chinese or Riichi (Japanese) mahjong set contains 136 tiles. American Mahjong sets contain 152 tiles, which include the standard 136 base tiles plus 8 flower tiles and 8 joker tiles. The exact count depends on which variant you are playing.
Mahjong is designed for exactly 4 players. Some variants include rules for 3-player games (such as Sanma in Japanese Riichi), but the standard and most common format requires four people seated at a square table, each building one side of the tile wall.
American Mahjong uses 152 tiles (including 8 jokers), requires hands to match patterns on the annually updated NMJL card, and features a unique pre-game tile exchange called the Charleston. Chinese variants use 136–144 tiles, have no jokers, and allow any hand that meets the standard 4 sets plus 1 pair structure with the required minimum score.
A single round of mahjong takes 5 to 15 minutes. A complete game session consists of multiple rounds — typically 4 to 16 depending on the variant. A full session lasts 1 to 3 hours. Casual games with experienced players move faster than beginner sessions.
The basic mechanics of mahjong — draw a tile, discard a tile, complete sets — are straightforward and most beginners grasp them within one session. The challenge comes from learning scoring rules, tile efficiency, and defensive strategy. Most new players feel comfortable after 3 to 5 practice games.
