How to Play American Mahjong

A beginner's guide to the tiles, the card, the Charleston and how a game is won.

American mahjong in a nutshell

American mahjong is a game for four players, built around tiles and a card of winning hands. Each player builds a hand of 14 tiles that matches one of the hands on the card. The first to complete a hand calls "Mahjong!" and wins the game.

It is a game of skill, strategy and a little luck, and it is very social. Most people learn it in an afternoon and spend years getting better.

The tiles

A standard American set has 152 tiles:

Some groups also play with blanks, extra plain tiles that let a player trade a blank for a discarded tile. In Mahj Muddle, the match type tells you whether blanks are in play: Modern and Party are played with blanks, Traditional and Power without.

The card

Every year the National Mahjong League publishes a new card listing that year's winning hands, grouped into sections. Every player needs the current card; you can buy it from the National Mahjong League. The hands change each year, which keeps the game fresh.

A hand on the card shows exactly which tiles you need: which numbers, which suits, which groups, and whether the hand must stay concealed.

How a game goes

  1. Build the wall. The tiles are shuffled face down and stacked into a wall in front of each player.
  2. Deal. Each player takes 13 tiles. East, the dealer, takes 14 and starts.
  3. The Charleston. Before play, everyone passes tiles they don't want to their neighbors, three at a time, in a set order: right, across, left. A second round is optional, then a courtesy pass across. It is the best chance to steer your tiles toward a hand.
  4. Play. On your turn you take a tile from the wall and discard one, face up. Play moves around the table.
  5. Calling a discard. You may claim another player's discard when it completes a group of three or more (an exposure, laid face up) or when it gives you Mahjong.
  6. Mahjong! The first player whose 14 tiles exactly match a hand on the card wins. If the wall runs out first, it is a wall game and nobody wins.
