The first time you sit down to play American Mahjong, the tiles are not usually the most intimidating part.
It is the card.
Small, laminated, and dense with numbers, letters, colors, abbreviations, and hand patterns, the NMJL card can feel like the secret menu of the entire game. Everyone at the table seems to be checking it constantly, yet no one is stopping mid-game to explain why one line is red and green, why another says “C,” or why five matching tiles can somehow exist when there are only four of each tile.
The good news: the NMJL card is not meant to be memorized at first. It is meant to be read. Once you understand its logic, the card becomes less like a code and more like a map.
What Is the NMJL Card?
The NMJL card is the annual card of official hands and rules used for American Mahjong. It is published by the National Mah Jongg League, the organization that standardized American Mah Jongg and continues to publish the official yearly card.
In American Mahjong, you do not win by making any combination that seems reasonable. You win by completing one of the valid hands printed on the current year’s card.
That is what makes the card so central. If your final tiles do not match a hand on the card, you do not have Mah Jongg.
Unlike many Mahjong styles where winning structures stay more fixed, American Mahjong refreshes its hands each year. The NMJL explains that American Mah Jongg uses a card of standard hands, and that these cards are changed annually (National Mah Jongg League, 2026).
That yearly reset is part of the culture of the game. Each spring, experienced players and beginners open the same new card and begin studying it together.
Where Do You Get the NMJL Card?
The official card is available through the National Mah Jongg League .
For 2026, the NMJL store lists the card at $14 for the standard version and $15 for the large-print version (National Mah Jongg League, 2026). Many clubs order cards together, especially when a new card is released.
If you are learning American Mahjong for the first time, the large-print card can be worth the extra dollar. It is easier to read at the table, especially while you are still getting comfortable with the notation.
The Basic Anatomy of the Card
The NMJL card is usually read as a compact folding reference.
The outside identifies the year and official card. The inside panels list the playable hands, organized by category. The back of the card includes rule reminders, scoring notes, and other reference details.
For a new player, the most important area is the inside. That is where you scan for the hand you are trying to build.
Do not worry about understanding every section immediately. At first, your goal is simple: learn where the hands are, how the categories are organized, and what the notation is telling you.
Why the Card Feels Confusing at First
The card is compact by design. It has to fit an entire year’s worth of winning hands into a small format, which means it relies on shorthand.
You will see numbers, letters, colors, spaces, C or X markings, point values, and notes in parentheses.
The card is not hard because the logic is random. It is hard because the logic is compressed.
Once you learn what the shorthand means, the card starts to open up.
The Three Suits: Craks, Bams, and Dots
American Mahjong uses three numbered suits: Craks, Bams, and Dots.
Each suit has tiles numbered 1 through 9. The tile itself tells you which suit it belongs to. Craks have Chinese characters, Bams show bamboo, and Dots show circles.
This matters because one of the most common beginner mistakes is assuming the printed colors on the card correspond to fixed suits.
They do not.
Red does not always mean Craks. Green does not always mean Bams. Blue does not always mean Dots.
The colors on the card tell you how many suits are involved in a hand and which tiles must share the same suit. You choose the suit assignment as you play.
If the tile names still feel visually confusing, start with our visual guide to reading Mahjong tiles. It gives you a clearer beginner-friendly reference for Craks, Bams, Dots, Winds, Dragons, Flowers, and Jokers before you try to decode the card itself.
How to Read the Colors on the Card
The card uses color as a grouping system.
If a hand is printed in one color, the suited tiles in that hand use one suit. You choose whether that suit is Craks, Bams, or Dots.
If a hand uses two colors, the hand requires two different suits. Tiles printed in the same color share the same suit. Tiles printed in different colors must be different suits.
If a hand uses three colors, the hand uses all three suits.
The color system is not naming the suits. It is showing the relationship between them.
For example, if a hand shows one group in red and another group in green, you might decide that red is Bams and green is Dots. Another player could use the same hand with red as Craks and green as Bams. Both can be correct, as long as the color logic stays consistent within that hand.
Think of color as a suit pattern, not a suit label.
What Do the Letters Mean?
The card also uses letters for non-numbered tiles.
F means Flower.
N, E, W, and S refer to the four Winds: North, East, West, and South.
R, G, and 0 usually refer to Dragons: Red Dragon, Green Dragon, and White Dragon.
The white dragon is often shown as a zero because the tile itself is commonly blank or represented as a soap.
This is one of those details that feels strange for the first few games and completely normal later.
Reading Tile Groupings: Pairs, Pungs, Kongs, and Quints
On the card, tiles are grouped together in clusters. The size of the cluster tells you what kind of grouping you need.
A pair is two matching tiles.
A pung is three matching tiles.
A kong is four matching tiles.
A quint is five matching tiles.
So if you see 11, that means a pair of ones. If you see 111, that means a pung of ones. If you see 1111, that means a kong of ones.
A quint requires five of the same tile, which sounds impossible because there are only four of each tile in a Mahjong set. That is where Jokers come in. The NMJL notes that American Mah Jongg uses Jokers, including to complete quints and other hand combinations (National Mah Jongg League, 2026).
For a deeper breakdown, our guide to jokers in American Mahjong can help clarify where jokers are useful, where they are limited, and why they matter so much in American Mahjong.
Concealed vs. Exposed Hands
Two letters on the card matter enormously: C and X.
C means concealed.
X means exposed.
A concealed hand must be built without calling discarded tiles, except when calling the final tile to declare Mah Jongg. These hands are usually harder because you have less control over what you can take from the table.
An exposed hand allows you to call a discarded tile when it completes an eligible grouping.
This is not a small detail. If you are working toward a concealed hand and you call a discard too early, you may ruin the hand.
Before calling a tile, glance at the card and confirm whether your target hand is marked C or X.
C and X are small letters with very real consequences.
Do Not Skip the Notes in Parentheses
The small notes beside a hand matter.
Parentheses often clarify whether the hand can use any suits, any like numbers, specific dragons, or a particular arrangement. These notes may look secondary, but they can change whether your hand is valid.
Before committing to a hand, read the full line: the tiles, the colors, the C or X marking, the point value, and the note beside it.
The fine print is part of the hand.
How the Card Is Organized
The NMJL card is divided into categories. The exact hands change from year to year, but the broad structure feels familiar once you play a few times.
You will often see sections such as year hands, consecutive runs, quints, odd-numbered hands, winds and dragons, 369, like numbers, addition hands, and singles and pairs.
These categories help you scan the card faster. Instead of reading every line from top to bottom after the deal, start with what your tiles are already telling you.
Have several odd numbers? Look at the odd-numbered section.
Have winds and dragons? Start there.
Have numbers in sequence? Check consecutive runs.
Have the same number across suits? Look at like numbers.
The category names are not decorative. They are search tools.
How to Choose a Beginner-Friendly Hand
After your tiles are dealt, resist the urge to decide too quickly.
Instead, scan your rack and ask:
-
What numbers appear more than once?
-
Do I have an obvious suit direction?
-
Do I have Flowers, Winds, Dragons, or Jokers that suggest a category?
-
Am I close to a real hand, or am I just hoping?
A good beginner strategy is to keep one primary hand and one backup hand in mind. The primary hand is the one that currently fits best. The backup hand gives you somewhere to pivot if the game starts moving in another direction.
This is especially useful during and after the Charleston, when your hand can change quickly. For quick reference at the table, use our free printable Charleston guide, designed to make the passing sequence easy to scan while you play.
One more rule helps: be careful with hands that require many singles and pairs. They may look simple, but they are often harder to complete because those tiles usually have to be drawn naturally. Unless your rack is already unusually close, a hand with clearer groupings may be more forgiving.
The card is not asking you to force a hand. It is asking you to recognize one.

Before You Declare Mah Jongg
Before calling Mah Jongg, check the hand against the card one last time.
Confirm the grouping sizes.
Confirm the suit colors.
Confirm whether the hand is concealed or exposed.
Confirm that any Jokers are allowed in the groupings you used.
Confirm that the notes in parentheses still match your hand.
A few extra seconds can save you from an incorrect declaration.
That pause is not hesitation. It is good table discipline.
A Simple Way to Keep Learning
Start with one section of the card at a time. The full card is too much to absorb in one sitting, but one category is manageable.
Keep the card visible while you play. Say the hand out loud when you study it. Check the card often. Everyone does.
For newer players, a clean setup also helps. A Mahjong mat with a smooth playing surface can make the table feel more organized while you are learning to sort tiles, read groupings, and manage discards.
You may also want the complimentary American Mahjong Cheat Sheet as a quick reference for tile types, basic terms, and beginner rules.
At first, the NMJL card feels like a barrier. Then it becomes a tool. Eventually, it becomes part of the pleasure of the game: the scanning, the narrowing, the almost-there feeling when your tiles begin to resemble a line you have been watching all night.
American Mahjong is not only about drawing the right tile.
It is about learning how to see what your hand is becoming.
