The Rules

American Mahjong in plain English. Every tile reads in English on its face, and discards are called the way they are at a real table — "Three Bam", "Five Crak", "Soap".

Calling your discard

When you throw a tile you say its name out loud so the table can claim it.

  • Number tiles: the number then the suit — "Two Bam", "Six Dot", "Nine Crak".
  • The white dragon is always "Soap". The others are "Red" and "Green".
  • Winds are just the direction: "East", "North".
  • Flowers are "Flower"; a discarded joker is dead and can't be claimed.

Three suits of 1–9, four winds and three dragons (four copies of each) — plus 8 flowers and 8 jokers, which are what make the American game different.

How a hand plays

1

Deal

Everyone gets 13 tiles; the dealer starts with 14 and discards first.

2

The Charleston

Three blind passes — right, across, left — of three tiles each, then an optional second round. Jokers may never be passed. This is where you shed the tiles that fit no card line.

3

Draw and discard

On your turn you draw one tile from the wall and discard one, calling it out. Play moves to the right.

4

Claiming a discard

Any player may take the most recent discard only to immediately complete an exposure — a pung (3), kong (4) or quint (5) — or to win. There are no runs to claim in the American game. An exposure goes face-up on your rack and you then discard.

5

Jokers

A joker may fill any spot in a pung, kong or quint, but never a single or a pair. If you hold the natural tile, you may swap it for a joker showing in anyone's exposure. A discarded joker is dead and cannot be claimed.

6

Mahjong

Call mahjong when your 14 tiles exactly match one line on the card. If the wall runs out first, the hand is a wall game and nobody scores.

Scoring

Each card line is worth its printed value — typically 25 to 75 points. Two bonuses apply on top:

  • Self pick — you drew your own winning tile: +10, and everyone pays double.
  • Joker free — you won an exposable line with no jokers at all: +10.
  • If you win off a discard, the discarder pays double and the other two pay single.

The Mahjong Club Card

Every winning hand must match one of these lines exactly. Numbers repeat as written; letters mean flowers (F), dragons (D for the dragon matching your suit, R red, G green), winds (E S W N) and "any like number" (N). A 0 is the white dragon — Soap. A vertical bar marks a change of suit.
