how to Read the Nmjl Card
A section-by-section walkthrough of the NMJL card, from suit colors and dragon symbols to concealed hands and point values.
The Short Answer
The NMJL card lists every legal hand for the year, grouped into sections by theme, with each line showing one hand as a string of numbers and letters. Read left to right: each group of characters is a set of tiles, the ink color tells you which groups share a suit, and the letter at the far right tells you whether the hand can be exposed or must stay concealed.
What the Card Actually Is
The National Mah Jongg League publishes a new card each year, and it's the rulebook for what counts as a winning hand in American mahjong. If a combination of fourteen tiles isn't printed on the card, it isn't a hand. That's the part that surprises people coming from other mahjong styles. You aren't building whatever you like. You're chasing one of the specific patterns in front of you.
How the Card Is Organized
Hands are grouped into sections with headings across the top of each block. You'll typically see a year section, Even Numbers, Like Numbers, Consecutive Run, 13579, Winds and Dragons, 369, Quints, and Singles and Pairs. Section names shift a little from year to year. Under each heading sit several lines, and every line is one complete, playable hand.
Reading a Single Line
Take an example line: FF 1111 2222 3333. That's two flowers, then a kong of 1s, a kong of 2s, and a kong of 3s. Count the characters and you'll always land on fourteen tiles. The spaces between groups matter, because they tell you where one set ends and the next begins.
Colors Are the Part People Miss
The numbers on the card are printed in different colors, and the colors do not mean bams, cracks, or dots. They mean "different suits from each other." If the 1s are blue and the 2s are red, those two groups must be in two different suits. You choose which. Same color means same suit, every time.
| Notation on the line | What it means |
|---|---|
| Any 1 Suit | All numbered groups come from one suit |
| Any 2 Suits | Two suits used, colors show which groups pair up |
| Any 3 Suits | All three suits appear, one per color |
The Symbols and What They Stand For
Numbers stand for numbered tiles in a suit. The letters carry the rest of the meaning, and once you know four of them, the card stops looking like code.
- F is a flower. Flowers have no suit and are interchangeable.
- D is a dragon. In a suited hand, the dragon has to match that suit's dragon.
- N, E, W, S are the four winds. Winds belong to no suit.
- 0 in a year hand is the white dragon, the tile most players call the soap.
The Dragon Rule Worth Memorizing
Dragons are tied to suits. Green dragons go with bams, red dragons go with cracks, and white dragons go with dots. So if a line reads DDD in green ink alongside green numbers, those numbers must be bams. Get this backwards and you'll build a hand that can't be declared.
Concealed or Exposed: the C and the X
At the right end of every line you'll find either a C or an X. C means the hand must be played concealed, so you cannot call a discarded tile and expose a set. X means you may expose sets by calling tiles from the discard pile. Concealed hands are harder to complete, which is why they're usually worth more points.
Point Values
The number printed beside each line is what the hand pays. Values start low for the common, flexible hands and climb for the ones that demand rare tile combinations or full concealment. Beginners often chase the high-value lines and end up with nothing. A finished 25-point hand beats an unfinished 50 every time.
Where Jokers Fit In
Jokers are not printed on the card, but they change how you read it. A joker can stand in for a tile inside any group of three or more, so pungs, kongs, and quints are joker-friendly. Jokers cannot be used for a single or a pair. That's why the Singles and Pairs section is the toughest block on the card.
How to Actually Pick a Hand
At the start of a game, sort your tiles and look for what you already have the most of, then scan the card for lines that use it. Two or three flowers point you toward hands with FF or FFFF. A cluster of even numbers narrows you to a section immediately. Hold two options open for the first several turns before committing.
Mistakes That Cost Games
The four common ones are misreading the colors as fixed suits, using a mismatched dragon, exposing a tile in a concealed hand, and switching hands too late to finish. There's a fifth. Players forget to recount the line and end up one tile short of fourteen. Count the characters before you commit.
Practicing With the Card in Hand
Reading the card gets easier with tiles in front of you, not on paper. Deal yourself thirteen tiles, then talk yourself through which sections are still possible and which are already dead. Do that a dozen times and the layout stops feeling like a wall of numbers. Most players cross that line faster than they expect.
Learning American Mahjong Around Orlando
Mahj & Away runs beginner lessons and open play for American mahjong across Orlando, Windermere, Winter Garden, and Winter Park. Sessions have been held at spots including Tim's Wine Market and Matthew's Steakhouse, which makes for a friendlier first game than a quiet table at home. Bring the current card if you have one. If you don't, that's fine too.
Frequently Asked Questions
Why are the numbers on the NMJL card printed in different colors?
Color indicates suit separation, not a specific suit. Groups printed in the same color must be in the same suit, and groups in different colors must be in different suits. You choose which actual suits to use, as long as the relationships on the card hold. Many new players assume blue means dots or green means bams. It doesn't.
What do C and X mean at the end of a line?
They tell you whether the hand can be exposed. X means you're allowed to call discarded tiles and lay sets face up on your rack. C means the hand must stay concealed until you decl
