American mahjong is a four player tile game of skill, strategy and a little luck. If you have watched a game and felt lost, do not worry. Most of what looks complicated is simply unfamiliar, and the rules come together quickly once you learn a few core ideas. This guide walks you through everything a beginner needs, from the tiles and the setup to the Charleston, the card, and how to actually win a hand.
What makes American mahjong different
Mahjong has many versions around the world. The American game, governed by the National Mah Jongg League, has one feature that sets it apart: the card. Every year the League publishes a card that lists the exact hands you are allowed to make that season. Instead of memorizing open ended patterns, you build your hand to match one specific line on the card. That card is the heart of the American game, and a new one is released each spring, so players refresh their card every year.
What you need to play
To start a game you need three things.
- A set of tiles. An American mahjong set has 152 tiles in play, which is the standard 144 tile set plus 8 jokers. Many retail sets, including ours, come with a few spare tiles on top of that, so you will often see them sold as 160 tile sets. You can browse our full range of American mahjong tile sets to find a design you love.
- Four racks. Each player lines their tiles up on a rack so only they can see their hand, and pushers help move the wall during setup. A matching set of acrylic racks keeps the table tidy and the game moving.
- The current card. Every player at the table needs this season's National Mah Jongg League card, since all legal hands come from it.
A mahjong mat is not required, but it protects your table, quiets the tiles and gives the wall a surface with grip. If you like to play while traveling, an all in one travel set packs tiles, racks, a mat and dice into a single case.
Meet the tiles
The 152 tiles break down into a few families:
- Suits, numbered 1 to 9: Dots, Bams and Craks, with four of each tile, for 108 suit tiles in total.
- Winds: North, East, South and West, four of each.
- Dragons: Red, Green and White, four of each. In American play each dragon is paired with a suit.
- Flowers: eight flower tiles, used in many hands on the card.
- Jokers: eight wild tiles, the piece that makes the game uniquely American.

Setting up the game
Four players sit around the table. Everyone takes a rack, and the tiles are shuffled face down. Each player builds a wall of tiles in front of their rack, and the four walls form a square. Dice decide where to break the wall, and tiles are dealt around the table until each player holds 13 tiles. The dealer, known as East, takes one extra tile to start with 14. You arrange your 13 tiles on your rack, hidden from the other players, and the game is ready to begin.
The Charleston
Before real play starts, American mahjong has a unique step called the Charleston, a set of tile exchanges that lets everyone improve their starting hand. In the first Charleston you pass three tiles to the right, then three across, then three to the left. If all four players agree, you play a second Charleston passing left, across, then right. After that comes an optional courtesy pass across the table of up to three tiles. One important rule for beginners: you never pass a joker during the Charleston.
Choosing a hand from the card
With your tiles in hand, open the card and look for a hand you can realistically build. The card is organized into sections, and each line shows a pattern of tiles plus its point value and whether it must be concealed. Early on, keep your options open and let your tiles guide you toward one or two possible hands rather than locking in too soon. Flexibility is one of the biggest skills in the American game.
Playing a turn
Play moves counterclockwise. On your turn you draw a tile, decide whether it helps your hand, and then discard one tile face up, saying its name out loud. What makes the game lively is that you do not have to wait for your turn to use a discard. If another player throws a tile you need, you may call it to complete a group of three or more matching tiles, then place that group face up on your rack as an exposure for everyone to see. Calling a tile speeds your hand along, but it also tells your opponents what you are building, so it is a tradeoff.
How jokers work
Jokers are wild, with a few firm rules. A joker can stand in for a tile inside a group of three or more identical tiles, such as a pung or a kong, but it can never be used as a single tile or as one of a pair. If a joker is sitting in another player's exposed group, you can swap the real tile it represents for that joker on your turn, which is a great way to stock up. You cannot call a discarded tile to pair with a joker, and you cannot call for a joker itself.
How to win
You win, or declare Mah Jongg, when your 14 tiles exactly match one complete line on the card. Call it out, lay your hand down and let the table confirm it against the card. Your score is the point value printed next to that hand, and the card rewards harder hands, often doubling the value for hands made without any jokers or kept fully concealed. If the wall runs out before anyone wins, the hand is a wall game and no one scores.
A few tips for your first games
- Pick two possible hands during the Charleston and stay flexible until the tiles commit you.
- Watch what other players discard and expose, since it reveals what they are building.
- Do not sit on jokers forever. They are powerful, but a joker you never use scores nothing.
- Keep the card in front of you. Nobody memorizes it at first, and that is completely normal.
- Play on a mat for grip and quiet, so shuffling and pushing the wall stays smooth.
Ready to play
The fastest way to learn is to set up a table and start. If you are putting your first kit together, begin with a full tile set, add a set of racks and a mat, and pick up this year's card. Within a game or two, the card stops looking like a puzzle and starts feeling like a map.
