Quick answer

American mahjong is a game for 4 players using 152 tiles. Each player tries to build a 14-tile hand that matches one of the hands printed on a card.

A game has three parts:

  1. The Charleston: everyone passes unwanted tiles to the other players.
  2. Draw and discard: players take turns drawing a tile and throwing one away, and can call other players' discards.
  3. Mahjong: the first player to complete a hand wins and is paid by the others.

Three numbered suits, plus Winds, Dragons, Flowers and Jokers.

Total152

Each Dragon belongs to a suit

On the card, a hand that says "matching dragon" uses the Dragon of that suit:

  • Red Dragon goes with Craks.
  • Green Dragon goes with Bams.
  • White Dragon, called Soap, goes with Dots. Soap also stands for the number zero, for example in year hands like 2 0 2 6.

2Pairs, pungs, kongs and quints

Every hand is built from groups of the same tile. The group names tell you the size.

NameSizeExampleJokers allowed?

Pung3 alike✓ Yes
Kong4 alike✓ Yes
Quint5 alike✓ Yes
Sextet6 alike✓ Yes

3The card: the list of winning hands

You can only win with a hand that is printed on the card you are playing with.

Each line on the card is one hand of exactly 14 tiles. Colors show suits: everything in one color must be the same suit, and different colors must be different suits.

  • X next to a hand means you may call discards and show groups face up ("exposed").
  • C means "concealed": you must build it from tiles you draw yourself. You may only call the very last tile, to win.
  • The number on the right is the value: what each other player pays when you win.

The official card used in most clubs is published once a year by the National Mah Jongg League. You buy it from them. On this site we use our own free Practice Card, which is built the same way and is great for learning.

4Setting up the table

The dealer is East and starts with 14 tiles. Everyone else gets 13.

  1. Pick East.One player is East (the dealer). The others are South, West and North, going to East’s right.
  2. Build the wall.Shuffle the tiles face down. Each player builds a wall 19 tiles long and 2 tiles high, which is 38 tiles each.
  3. Break the wall.East rolls the dice and counts along their own wall to find where dealing starts.
  4. Deal.Players take tiles four at a time. At the end East has 14 tiles and everyone else has 13.
  5. Rack your tiles.Stand your tiles on your rack so only you can see them.

5The Charleston

Before play starts, everyone passes three tiles at a time, so you can get rid of tiles you do not want.

2AcrossYes
3LeftYes
4 to 6Left, across, rightOnly if every player agrees

You can never pass a joker. Read the full guide: The Charleston, step by step.

6Taking turns: draw and discard

East throws first. After that, each player draws one tile and throws one tile.

  1. East discards.East already has 14 tiles, so East starts by discarding one tile face up in the middle and saying its name out loud, for example "5 Dot".
  2. Next player draws.Play moves to the right (counterclockwise). The next player draws a tile from the wall.
  3. Then discards.They throw one tile and name it. You always have 13 tiles at the end of your turn.
  4. Repeat.Keep going until someone wins or the wall runs out. A game with no winner is called a wall game, and nobody pays.

7Calling a discard

You may take another player’s discard if it completes a pung, kong, quint or sextet, or if it wins the game.

Say "call" (or "Mahjong" if it wins). Then put the group face up on top of your rack, discard a tile, and play continues to your right. Players in between lose their turn.

You want the discard for…Can you call it?
A pung, kong, quint or sextet✓ Yes
A pair or a single✗ No, unless it is the tile that wins the game
A concealed (C) hand✗ No, unless it is the tile that wins the game
Mahjong✓ Yes, and Mahjong beats every other call

More detail: calling tiles and exposures.

8Jokers in one minute

A joker can replace any tile in a group of three or more. It can never be part of a pair or a single.

Allowed: a joker completes a pung of 3 Bam.
Not allowed: a joker cannot make a pair.

On your turn you can also swap a real tile for a joker in any exposed group. Read more: Joker rules.

9Winning and paying

Call "Mahjong!", lay all 14 tiles face up, and the others pay you the value on the card.

Hands in the Singles and Pairs section cannot use jokers anyway, so they do not get the jokerless double. Full guide: paying and scoring, or try the payment calculator.

10Mistakes and dead hands

If your hand can no longer match any line on the card, it is "dead": you stop playing but still pay at the end.

  • Wrong number of tiles. If you end your turn with more or fewer than 13 tiles, your hand is dead.
  • Impossible exposures. If the groups you have laid face up do not fit any hand on the card, your hand is dead.
  • Calling Mahjong by mistake. If you have not shown your tiles yet, you can usually take it back and keep playing. Many tables agree on their own house rule here.

11Five tips for your first games

Choose two or three hands early, keep your jokers, and watch what other players collect.

  1. Look for your best section.After the deal, count which section of the card your tiles fit best: evens, odds, runs, winds and dragons, and so on.
  2. Keep two or three hands in mind.Do not commit to one hand too early. The Charleston will change your tiles.
  3. Never throw a joker early.Jokers are the most useful tiles in the game. Keep them for your groups.
  4. Watch exposures.If a player has two pungs of Dots face up, do not feed them Dots.
  5. Switch when you must.If the tiles you need are all gone (four 5 Bams already on the table), change to another hand.
