What do the colours on a mahjong card mean?

Colour tells you whether groups share a suit, not which suit. Groups printed in the same colour must be the same suit; groups in different colours must be different suits. Which actual suit is your choice.

What do X and C mean on a mahjong card?

X means the hand may be exposed, so you can call discards and lay groups face up. C means the hand must be concealed — you may expose nothing, and the only discard you may take is the one that completes the whole hand.

What does 0 mean on a mahjong card?

A zero inside a year is played as the white dragon, usually called the soap. A year hand such as 2026 is four single tiles, so no jokers can be used in it.

How many tiles is each line on the card?

Always fourteen. If your reading of a line does not add up to fourteen, you have misread it.

How to read a mahjong card: the shorthand, decoded

Every line is one legal hand. Once you can read the numbers, the colours and the two letters at the end, the whole card turns from a wall of code into a menu.

Written while drawing a beginner's reference sheet · updated September 2026

The hand card is the thing that makes American mahjong look impenetrable. It is a dense grid of numbers, letters and colours with no key printed on it, handed to you by people who have been reading it for thirty years and have forgotten that it needs explaining.

It does not need much explaining. There are about eight things to know, and then the card reads like English.

The one idea: each line is a complete hand

A line on the card is not a suggestion or a category. It is fourteen tiles, written out in shorthand, and to win you must hold exactly that. Every line on the card adds up to fourteen. If your count of a line comes to thirteen or fifteen, you have misread it — and counting to fourteen is the single most useful habit when you are learning.

The numbers

A digit means a tile of that number, and how many times it is repeated tells you how many of them you need:

Written	Means	Jokers?
1	A single tile	No
11	A pair	No — never
111	A pung: three identical tiles	Yes
1111	A kong: four identical tiles	Yes
11111	A quint: five, on the cards that print one	Yes, necessarily

So 111 222 3333 44 is a pung of ones, a pung of twos, a kong of threes and a pair of fours. Three plus three plus four plus four is fourteen. It balances, so you have read it correctly.

The letters

Letter	Tile
F	Flower. `FF` is two flowers, `FFFF` is four
D	Dragon. Its colour tells you which one
N E W S	The four winds
NEWS	One of each wind — four single tiles, so no jokers anywhere in it
0	A zero inside a year, which is played as the white dragon — the soap

So a year hand written 2026 is four single tiles: a 2, a soap, a 2 and a 6. Four singles means no jokers, which is why year hands are harder than they look.

The colours, which is the part nobody explains

This is where most beginners go wrong, so it is worth stating precisely.

The colour of the printing tells you whether groups are in the same suit or different suits. It does not tell you which suit.

Two groups printed in the same colour must be in the same suit.
Two groups printed in different colours must be in different suits.
Which suit is your choice, made from what you were dealt.

So a line printed with the first half in one colour and the second half in another can be played as dots-and-bams, or bams-and-craks, or craks-and-dots. Three ways into the same line. This is the single fact that most increases a beginner's options, and it is never written on the card.

Dragons inherit the same logic: in a line where a group is in a given colour, the dragon printed in that colour is the one that matches that suit. Tables will tell you this in half a sentence and assume you got it.

The letters at the end of the line

X — the hand may be exposed. You may call discards and lay groups face up while you build it.
C — the hand must be concealed. You may expose nothing. The only discard you may ever take is the one that completes the whole hand.
The number is what the hand pays.

The practical reading: X hands are faster and cheaper, C hands are slower and pay more. As a beginner, play X hands. Concealed hands with no jokers are how experienced players lose an evening gracefully.

Reading a line in four questions

This is the whole skill, and it takes about a week to become automatic. For any line:

How many tiles? Count to fourteen. If it does not come to fourteen, read it again.
How many suits, and are they forced? Look at the colours. Same colour, same suit; different colours, different suits; and you choose which.
Where can jokers go? Anywhere a group is three tiles or more. Nowhere else. A line that is mostly pairs and singles is a line where your eight jokers are worth nothing.
X or C, and what does it pay? Then decide whether you can realistically get there from the thirteen tiles in front of you.

Three habits that make the card shrink

Learn three lines, not eighty. Pick three you can recognise on sight — ideally one that uses flowers, one that uses a single suit and one year hand — and let the rest arrive over months.
Mark your card. A pencil tick next to the lines you have actually won with is worth more than any advice on this page. Most players' cards are covered in marks.
Write down what you are chasing. A hand tracker sheet — the line you picked, the fallback, what you are still missing — turns the Charleston from a guess into a decision, and it is the one habit that visibly improves a beginner inside a single evening.

Why the card changes and why that is fine

Hand lists are reissued every year, and every year somebody says they finally understood the old one. It matters less than it feels like it does. The tiles, the Charleston, the joker rules, the call rules and the shorthand never change. Only the list of hands does. Learn the grammar and the new card is a new vocabulary, not a new language.

From our own shop

Two things we make for exactly this problem. The American Mahjong Cheat Sheet, $9.99 has a full page on the shorthand above, plus the tiles, the Charleston, the joker rules and a pocket card for reading the card — deliberately with no hand list in it, so it is still correct when your card is reissued. And the Mahjong Hand Tracker, $8.99 is the blank sheet for writing down what you are chasing, in pocket and large-print sizes.

We are not affiliated with, endorsed by, or reproducing the card of any mahjong organisation. Hand lists are reissued every year; use your own current official card.

The one-paragraph version

Each line is fourteen tiles. Repeated digits are how many of that tile you need. Letters are flowers, dragons, winds, and a soap standing in for a zero. Same colour means same suit, different colours mean different suits, and you pick which. Jokers only go in groups of three or more. X means you may expose, C means you may not, and the number is the payout. That is the card.
