How to Play American Mahjong: A Beginner's Guide (2026)

By Keen, Maker behind Spools
The short version: American Mahjong is a four-player tile game played with 152 tiles, four racks, and the current year's card from the National Mah Jongg League. You pass tiles in a ritual called the Charleston, then draw and discard until someone completes a hand that matches the card and calls "Mahjong." It looks complicated, but it breaks into five simple parts, and most people can play a real game after two or three sessions.
American Mahjong is having a moment. It is filling club tables, kitchen counters, and poolside afternoons across the country. If the tiles look intimidating, that is only because nobody has walked you through them in plain English yet. This guide does exactly that. By the end you will know what is in a set, how a hand is played from start to finish, and what you actually need to buy to start playing.
What is American Mahjong?
American Mahjong is a tile-based game of skill and luck for four players. Its roots trace back to 19th century China, and the game arrived in the United States in the 1920s. In 1937, a group of players in New York City founded the National Mah Jongg League, or NMJL, to standardize the rules. The League still publishes a new card of legal hands every year, and that yearly card is what makes the American game its own animal.
If you have played Chinese Mahjong, the American version will feel familiar in spirit but different in the details. Here is how they compare.
| Feature | American Mahjong | Chinese Mahjong |
|---|---|---|
| Tiles | 152 (with jokers) | 144 (no jokers) |
| Winning hands | Set list on a yearly NMJL card | Flexible, player builds freely |
| Jokers | Yes, 8 wild tiles | No |
| Charleston | Yes, a tile-passing ritual | No |
| Racks | Yes, tiles held upright | Usually not |
What you need to play
You need surprisingly little to get started. Here is the full list.
- A set of tiles. A standard American set has 152 tiles. Many modern sets add extra jokers and blanks so you can play house rules. Our travel Mahjong tiles ship with 160 tiles: 144 base tiles, 10 jokers, and 6 blanks.
- Four racks. One per player, to hold your tiles upright and hidden. Our travel racks are a full 20 inches long but split in two so they fit in a bag.
- Four pushers (optional but nice). These help you push the wall of tiles into the center. You can add matching pushers to any set.
- The current NMJL card. This lists every legal winning hand for the year and changes each spring. You buy it separately, usually for around fifteen dollars.
- A mat (optional). A soft Mahjong mat keeps your table quiet and your tiles scratch-free.
Total cost to start is modest, and a good set lasts for years. If you want to make your set your own, you can even order custom jokers or blanks.
Understanding the tiles
Every tile falls into one of a few groups. Learn these and the card stops looking like a foreign language.
| Tile group | What it is | How many |
|---|---|---|
| Dots (circles) | Suit numbered 1 to 9 | 36 |
| Bams (bamboo) | Suit numbered 1 to 9 | 36 |
| Cracks (characters) | Suit numbered 1 to 9 | 36 |
| Winds | North, East, South, West | 16 |
| Dragons | Red, Green, White (soap) | 12 |
| Flowers | Decorative, used across hands | 8 |
| Jokers | Wild tiles | 8 |
A few things worth memorizing early. Each dragon pairs with a suit: red goes with cracks, green goes with bams, and the white dragon, nicknamed "soap," goes with dots. Jokers are wild and can stand in for most tiles, but never for a single tile in a pair and never during the Charleston. That last rule trips up almost every beginner.
Setting up the game
Setup has a rhythm to it, and it is genuinely satisfying once you get the hang of it.
- Roll for dealer. Everyone rolls the dice. The highest roller becomes East, the first dealer.
- Shuffle. Turn all tiles face down and mix them thoroughly. This is the loudest, most fun part of the game.
- Build the wall. Each player builds a wall of tiles two rows high in front of their rack.
- Deal. Tiles are dealt around the table until each player has 13, and East has 14.
Because East starts with an extra tile, East opens play by making the first discard.
The Charleston, explained
The Charleston is the tile-passing ritual that makes American Mahjong unique. Before real play begins, players pass tiles they do not want and receive tiles they might. It is how a random deal turns into a hand with a plan.
The two rules that matter most: you pass exactly three tiles on each pass, and you may never pass a joker. Beyond that, the pattern is a series of passes to the right, across, and left, with a second Charleston that the table can agree to skip. Do not overthink your first few games. Pass away tiles that do not fit any hand you are eyeing on the card, and keep what does.
How a turn works
Once the Charleston is done, play moves counterclockwise and the loop is simple.
- Draw. On your turn, take the next tile from the wall.
- Discard. Choose a tile you do not need and place it in the center, saying its name out loud.
- Call. Any player can call the discarded tile if it completes a set they can expose. If you call, you show the set on top of your rack and then discard.
That is the entire engine of the game: draw, discard, and occasionally call. Everything else is strategy layered on top.
How to win
You win by being the first to complete a hand that exactly matches one of the patterns printed on the NMJL card, then declaring "Mahjong." Unlike other Mahjong variants where you build hands freely, the American game asks you to commit to one of the card's listed hands and assemble it. If the wall runs out before anyone wins, the round is a "wall game" and no one scores.
Scoring, kept simple
Each hand on the card has a point value printed next to it, usually ranging from 25 points for easier hands up to higher values for harder ones. The player who declares Mahjong collects from the other three based on that value, with extra owed by anyone who dealt the winning tile. You do not need to memorize any of this to start. The card does the math for you.
Common beginner mistakes
- Passing a joker. It is against the rules during the Charleston, and it is a waste any other time.
- Committing to one hand too early. Keep two options open on the card until your tiles tell you which to chase.
- Forgetting to name your discard. Say the tile out loud so others can call it. It keeps the table fair.
- Ignoring the discards. What others throw away tells you what they are not collecting, and what might be safe to release.
How long does it take to learn?
Most people can play a friendly, correct game after two or three sittings, and feel comfortable within a couple of weeks of regular play. The fastest path is to learn the tile groups first, then drill reading the card for ten minutes a day, then practice the Charleston until passing feels automatic. The real leap happens the moment you play a live hand with people who already know the game. Reading rules and sitting at a table are two different experiences, and the table wins every time.
Play anywhere you want to be
Here is the part most guides skip. Mahjong does not have to live on one dining table. The reason we built Spools was simple: a traditional set can weigh around fourteen pounds, which is a lot to haul to a friend's house, a beach rental, or a cruise. Our tiles are full-size and easy to read, but a whole set weighs about 1.6 pounds, less than a laptop, and every tile is designed to float if it goes in the pool.
That means game night can happen on a boat, a patio, a plane tray, or a hotel balcony. If you are still choosing a set, our 3D travel tiles are the most popular place to start, and our travel games guide covers what else is worth packing.

What is the difference between American and Chinese Mahjong?
American Mahjong uses 152 tiles including jokers, a yearly card of legal hands from the National Mah Jongg League, and a tile-passing ritual called the Charleston. Chinese Mahjong uses 144 tiles, no jokers, and lets players build hands freely.
Do I need the National Mah Jongg League card to play?
Yes, for standard American Mahjong. The card lists every legal winning hand for the year and changes each spring. It is sold separately and is inexpensive.
Can you play American Mahjong with three players?
The game is designed for four players. You can play with three by adjusting the setup, but four is the standard and the most balanced experience.
What is the Charleston in Mahjong?
The Charleston is a passing ritual at the start of each round. Players pass exactly three unwanted tiles at a time and receive new ones. You may never pass a joker during the Charleston.
