How to Read Your NMJL Card: A Complete Beginner's Guide

Jun 12

An American Mahjong set contains 152 tiles, and to a new player the variety can feel overwhelming: three different suits, four winds, three dragons, flowers, and jokers. The good news is that the tiles organize into a small number of families, and once you know the families, every tile in the set makes sense.

This guide walks through every tile type, what it's called, how many of each exist, and how each is used in play.

The Big Picture: 152 Tiles

A full American Mahjong set breaks down like this:

108 number tiles — three suits, numbered 1 through 9, with four copies of each tile
16 Wind tiles — North, East, West, and South, four of each
12 Dragon tiles — Red, Green, and White, four of each
8 Flower tiles
8 Joker tiles

That totals 152. Many sets also include a few blank spare tiles — those aren't used in standard play; they're replacements in case a tile is lost.

The Three Suits

The bulk of the set is number tiles, which come in three suits. Each suit runs from 1 to 9, and there are four copies of every tile (four 1 Bams, four 2 Bams, and so on).

Bams (Bamboos)

Bam tiles show stalks of bamboo — the number of stalks matches the tile's number. The one exception is the 1 Bam, which traditionally shows a bird (often a peacock or sparrow) instead of a single stalk. New players sometimes mistake the bird for a special tile; it's just the 1 of Bams.

Craks (Characters)

Crak tiles show a Chinese character along with a number. The name comes from "character." On most sets, the numeral is printed in Arabic numbers as well, so you don't need to read the characters to play.

Dots (Circles)

Dot tiles show circles — the count of circles matches the number. A 5 Dot has five circles. These are usually the easiest suit for beginners to read at a glance.

The three suits matter because the NMJL card frequently requires tiles from the same suit, or from two or three different suits. Telling Bams, Craks, and Dots apart quickly is one of the first skills worth building.

Wind Tiles

There are four Winds — North, East, West, and South — with four copies of each. On most American sets they're marked with the letters N, E, W, and S, matching how they appear in card notation.

Winds appear in many hands on the NMJL card, especially in the Winds and Dragons section. East also has a small ceremonial role: the dealer position is called East, and the deal rotates around the table.

Dragon Tiles

There are three Dragons, four copies of each:

Red Dragon — usually shows a red character or symbol
Green Dragon — usually shows a green character
White Dragon (the "Soap") — usually a blank tile with a blue or black border, resembling a bar of soap, which is where the nickname comes from

Two things make Dragons important in American Mahjong:

Each Dragon pairs with a suit. Red Dragons go with Craks, Green Dragons with Bams, and Soaps with Dots. When a hand on the card mixes Dragons with number tiles, the Dragon must match the suit of those numbers.
The Soap doubles as a zero. In hands built around the year or around arithmetic, the White Dragon stands in for the digit 0. This is unique to American Mahjong and surprises players coming from other variants.

Flower Tiles

American sets include eight Flowers. Unlike in some other Mahjong variants, Flowers in American Mahjong are not bonus tiles — they're ordinary working tiles that appear directly in hand patterns on the card, written as F in the notation.

All eight Flowers are interchangeable. A set may decorate them with different seasons, plants, or scenes, but for gameplay purposes a Flower is a Flower. If a hand needs two Flowers, any two will do.

Joker Tiles

The eight Jokers are the most distinctive feature of American Mahjong — most other variants don't use them at all. A Joker is wild: it can stand in for almost any tile.

The key restriction: Jokers may only be used in groups of three or more identical tiles (pungs, kongs, and quints). They can never represent a tile in a pair or a single. They also can't be used at all in the Singles and Pairs section of the card.

Jokers are powerful enough that they get their own strategy. For the full picture — including the swap rule that lets you reclaim exposed Jokers — see What Are Jokers in American Mahjong.

Reading Tiles Quickly

A few habits that help new players:

Sort your rack by family — suits together, then Winds, Dragons, Flowers, and Jokers at the end. Most players keep a consistent sorting order every game.
Watch for the lookalikes. The 1 Bam (the bird) and the Soap (the blank-ish White Dragon) are the two tiles new players misread most often.
Use the numerals. American sets print Arabic numerals on the suit tiles. There's no need to count stalks or circles under time pressure.

Putting It Together

Every hand on the NMJL card is built from these families — suits, Winds, Dragons, Flowers, and the Jokers that fill in the gaps. Once the tiles feel familiar, the card's notation starts mapping directly onto what's sitting in your rack.

To practice recognizing tiles in a real game setting, try a few rounds in Play mode — sorting and reading tiles gets fast surprisingly quickly with repetition.
