How to read a mahjong card, one line at a time
A mahjong card is a list of every hand that can win this season, written in a compact code. Learn the code once and the reading skill transfers whole to the official NMJL card or any other published card your table plays.
Each line on a card is one complete hand of exactly fourteen tiles, and only a full match wins. Digits are ranks, letters name flowers, dragons and winds, and repeating a symbol shows the size of the group. Groups that share a marking share a suit, the number at the end is the payout, and X or C says whether the hand may be played open or must stay concealed. Hands come grouped in sections, so learn those and sort each deal into the two sections it’s closest to.
This guide covers standard American mahjong. Tile artwork and house rules can vary; use the rules and card agreed on by your table.
A line is a hand
The card intimidates every single beginner, and it shouldn’t: there are about six ideas on it, repeated over and over. Here they are in the order you’ll meet them.
Each printed line is one complete fourteen-tile hand. Match all fourteen exactly, and only then, and the line’s value on the right is what your win pays. Thirteen of fourteen pays nothing.
Here’s a sample line, written the way a card prints it: FF 2026 4444 4444, worth 25 and marked X. It isn’t a hand from any real card, just practice. Read left to right: a pair of flowers, then 2-0-2-6, then a kong of 4s, then another kong of 4s. A pair is two matching tiles and a kong is four, so that’s fourteen tiles: two, four, four, four.
The letters and digits
Digits mean ranks. F is a flower, D is a dragon, and N, E, W, S are the four winds. A zero inside a year is played by the soap, the white dragon standing in for the digit 0.
Repetition tells you the group: FF is a pair of flowers, 111 is a pung of 1s, 4444 is a kong of 4s, and a lone letter or digit is a single. No joker may touch a single or a pair.
| Written as | What it is |
|---|---|
| 111 | A pung of 1s: three matching tiles |
| 4444 | A kong of 4s: four matching tiles |
| FF | A pair of flowers: two matching tiles, no jokers |
| A lone letter or digit | A single, which no joker may touch |
Shapes and colors carry the suits
The card never says “dots” or “bams”, because almost any hand can be built in any suit. Instead, groups that must share a suit share a marking. On our house card that marking is a color with a shape riding along, so the rule reads even in bad light: same shape, same suit; different shapes, different suits; no shape, suit doesn’t matter.
In the sample line, 2026 wears one shape and the two kongs of 4s wear two others, so the hand takes all three suits, one each. Which suit plays which shape is your choice at the table, and that flexibility is why one printed line stands for dozens of concrete hands.
The value and the calling mark
The number at the line’s end is the payout, and difficulty sets it: common shapes pay the floor, concealed hands and singles-and-pairs hands pay the ceiling.
Next to the value sits the calling mark. X means the hand may be played open, calling discards (claiming a tile another player throws away) and exposing groups face up on the way. C means concealed: no exposures until the win itself, though joker exchanges stay legal, since redeeming a joker exposes nothing.
| Mark | What it means |
|---|---|
| X | Open: you may call discards and expose groups on the way to the hand |
| C | Concealed: no exposures until the winning call itself. Concealed hands are harder, so they pay more. |
Sections are the real unit
Hands come grouped in sections: year hands, even numbers, odd numbers, runs, winds and dragons, singles and pairs. Individual hands rotate every season; the sections and their personalities barely move.
So skip memorizing lines. Learn what the hands in each section have in common, sort every fresh deal into the two sections it’s closest to, and read just those lines closely. That’s the whole method, and it’s the same method on our house card or a fifty-five-hand official one.

The lessons deal you a rack and ask the only question that matters: which section is this hand trying to be? You get quick at it in an afternoon.
Learn it interactivelyCommon questions
What do the colors on a mahjong card mean?
Colors distinguish suits from each other within one line, and they don’t name a specific suit. Groups sharing a color are one suit; different colors mean different suits. On our house card a shape rides along with every color, so the distinction never depends on color alone.
What does X mean on a mahjong card?
The hand may be played open: you can call discards and expose groups on the way to it. C means concealed, no exposures until the winning call itself. Concealed hands are harder, so they pay more.
What are the sections of a mahjong card?
Groups of related hands. A typical card groups year hands, even numbers, odd numbers, runs, winds and dragons, and singles and pairs. Learning the sections’ shapes is the actual skill; individual hands change every year, sections mostly don’t.
Do I have to memorize the card?
No, and trying is the classic beginner mistake. The card sits face up next to your rack the whole game. The skill is sorting a fresh deal into the two or three sections it’s closest to, and that comes from reps, not memorization.
Is every hand on the card 14 tiles?
Yes. Every legal hand on any American card is exactly fourteen tiles, which is thirteen in the rack plus the one that completes it.
