Every April, somewhere around the second or third week, a new mahjong card lands in mailboxes across the country. Players who pre-ordered open the envelope first. The rest scramble to find a copy. Tables that have spent a year getting comfortable with the same 55 hands suddenly have to learn 55 new ones. Hands you loved are gone. Hands you've never seen before are now the only thing on the page.
This is the NMJL card. It changes every year, on purpose, by design. Here's what the National Mah Jongg League actually is, why the card refreshes annually, how the process works, and what to do with the old card once the new one arrives. By the end of this you'll understand why your card looks the way it does and why next year's will look different.
TL;DR: The NMJL card in 6 lines
- The NMJL is the National Mah Jongg League, founded in 1937 in New York. It's the governing body for American mahjong.
- The League publishes one new card every spring. The 2026 card has 55 hands across 9 sections.
- The card changes every year to keep the game fresh, prevent pure memorization, and rotate hand difficulty.
- A current NMJL card costs $15 and arrives by mail.
- The old card is still useful for practice, transitional play, and teaching beginners core concepts. Tournament play moves to the new card right away.
- Other organizations publish cards too. The Big Card, Mahjong Press, and the American Mahjong Society are real alternatives. The NMJL card is the standard most American mahjong players use.
What the NMJL actually is
The National Mah Jongg League is the governing body for American mahjong. It's a nonprofit organization, founded in New York in 1937, and it has been publishing the official card every year ever since. The membership is large, widely estimated in the hundreds of thousands of active players who buy the card annually, making the NMJL one of the largest game-membership organizations in the country.
The League sets the rules for American mahjong, publishes the card each year, and donates a portion of card sales to charity. That charitable mission has been part of the League from the beginning. When you buy a card, a piece of the cost goes to causes the NMJL supports.
The NMJL is also where rulings come from when a question comes up at the table. Their bulletins and the official NMJL rules are the reference point for tournament play and for any disagreement that needs an outside arbiter. If your table can't agree on whether a Mahj is legal, the NMJL ruling is the tiebreaker.
How the League started: 1937 in New York
Mahjong arrived in the United States in the 1920s and exploded. By the mid-1920s, sets were selling out, mahjong parties were a national phenomenon, and the game had become a fixture in American living rooms. The problem was that nobody could agree on how to play. Every region, every neighborhood, sometimes every table had its own version of the rules. A game in Brooklyn and a game in Cleveland might be unrecognizable to each other.
The NMJL was founded in 1937 to fix that. A group of women in New York standardized the rules, published an official card, and gave American mahjong a single set of hands every player could agree on. That's the variant we still play today. When people say "American mahjong," they mean the version the NMJL codified almost 90 years ago.
The League was founded by women, run by women, and from the start it organized around the social and charitable mission that's still core to it. That's not a marketing line. It's the actual history.
Why the card changes every year
This is the question I get most about the NMJL card, and it has three honest answers.
1. It keeps the game fresh
If the card never changed, the game would get stale fast. Players would lock in on a small set of favorite hands and never have a reason to learn anything new. Every spring the card refresh gives every player at the table a reason to look at something different. The whole community is learning at the same time, which is part of what makes new card season feel like an event.
2. It prevents pure memorization
If the card stayed identical year after year, mahjong would become a memory game. The strongest players would be the ones who'd memorized every hand and every variation, and the game would lose the strategic reading-the-table element that makes it interesting. The yearly refresh forces every player, no matter how experienced, to re-learn. There's no "memorize and hope" anymore. You have to read the new card and decide what to play.
3. It rotates hand difficulty
Some cards are easier than others. Some years the hands have more flexibility. Some years the colors are harder to scan. Some years the parentheticals are denser. The NMJL doesn't publish their internal scoring of card difficulty, but anyone who's played for a few years can feel the difference. The yearly refresh means a "hard year" gets followed by a different distribution, and no one card defines the experience of American mahjong forever.
There's also a quiet fourth reason: the card sale funds the League and the charitable work that comes with it. A yearly refresh means a yearly purchase, which sustains the organization. That's not cynical. It's how a nonprofit governing body keeps going.
How hands get added and retired
The exact process for how hands enter and leave the card is not publicly documented. The NMJL has a card committee and the work is internal. What we can do is observe patterns from the cards themselves, because the patterns are visible if you look at multiple years side by side.
Some patterns I've noticed across recent cards:
- Hands that closely match the current year often appear in the year-number section. The 2026 card has hands built around the digits 2-0-2-6. The 2025 card had hands built around 2-0-2-5. This is the most reliable pattern across years.
- Old sections sometimes get reworked rather than replaced. The Like Numbers section is on every card, but the specific hands inside it shift. Same with Consecutive Run, Quints, Singles and Pairs.
- Hand difficulty seems to rotate. A card with a lot of low-flexibility hands one year is often followed by a card with more flexible options the next.
- Sometimes a beloved hand from a previous year comes back in a tweaked form. Players who've been playing for a decade will sometimes say "oh, this one is back."
The card committee includes people who play, teach, and have deep experience with the game. They're not picking hands at random. The process is opaque from the outside, but the result is a card that feels different every year while still being recognizably American mahjong.
When the card comes out and what to do with the old one
Release timing
The new NMJL card comes out every April. Pre-orders go out earlier in the year (the NMJL announces the open date in their bulletin and on their website), and physical cards arrive by mail in April. By late April most players have a copy. Tournament play and most teaching switches to the new card right away.
The new card officially replaces the prior year's card the moment it's released. That's the rule. But informally, there's a transition period. Many casual tables keep playing the old card for a few weeks while everyone gets their new one, and beginners often learn on whichever card is available rather than waiting for the new release.
Using last year's card
The old card doesn't become useless. Here's what I still use mine for:
- Practice. The old card is a free resource for drills. Run hands you remember well, test your scanning speed, work on your Charleston decisions with a deck of hands you already know.
- Transitional play. If your group hasn't all received the new card yet, playing on the old card for a few weeks lets you keep playing without the awkward delay.
- Teaching beginners. The core mechanics of card-reading don't change year to year. Beginners learning what a parenthetical means, how to read the color rules, or how the suits work can learn those concepts on any recent card. Once they understand the structure, switching to the current card is a small step.
- Comparison study. If you have two or three old cards, lay them next to the current card and look at what shifted. It's one of the best ways to start seeing the patterns in how the League builds a card.
What the old card is not good for: actual tournament play, current strategy content, or any setting where current-card knowledge matters. The hands change enough year to year that "I'm great at the 2025 card" doesn't fully translate to the 2026 card.
The NMJL card costs $15
A current NMJL card is $15. You order it through the NMJL's website or through a local distributor. It arrives in the mail, usually as a single bifold card printed on coated stock. There's also a large-print version available for the same price, which is worth knowing about if standard print is hard to read.
You can also buy old cards on the secondary market, though they're not officially sold by the League once a new card releases. Some teachers and players hold onto a small library of old cards for practice and reference.
Other organizations publish cards too
The NMJL is not the only game in town. There are alternative cards available, and serious players sometimes use them for variety or for specific kinds of play.
The Big Card
The Big Card is an alternative card built around larger print for easier readability. Players who find the standard NMJL card hard to scan sometimes use The Big Card instead. It's a separate publication with its own community of users.
Mahjong Press
Mahjong Press is another publisher that produces an alternative American mahjong card. Their card has a different hand selection and a different visual layout from the NMJL card.
American Mahjong Society
The American Mahjong Society is a newer organization that publishes its own card and operates as a separate community from the NMJL. They have their own membership, their own bulletins, and their own annual card release.
These alternatives don't replace the NMJL. They exist alongside it. If you're learning American mahjong for the first time, the NMJL card is the one to start with because it's the one almost everyone plays. But if you've been at this for years and want to see how the game can be played with a different hand structure, the alternatives are real and worth knowing about.
I'm not going to argue any one card is better than another. They each have a community and a purpose. The NMJL is the standard and that's where I teach. The others are options.
Why the card looks the way it does
If you've ever stared at the NMJL card and wondered why it's laid out the way it is, here's a quick read.
- Sections group hands by theme. Year-number hands (2026), Like Numbers, Consecutive Run, 13579, 369, Winds and Dragons, Quints, Singles and Pairs. Each section has its own organizing logic.
- Colors signal suits, not specific suits. The colors on a hand don't tell you which suit to use. They tell you how many different suits the hand needs. Two colors means two suits. Three colors means three suits. This is the single most useful card-reading shortcut for new players. (More on this in our how to read the NMJL card guide.)
- Parentheticals are the rules for that hand. Things like "Any 3 Suits" or "Pungs and Kongs" appear in parentheses next to the hand. These are not optional. Read them every time.
- Point values appear on the right. Higher point values usually go to harder hands. The point structure rewards harder hands without making them mandatory.
- X marks a Concealed hand. The C designation marks a hand that has to be played without picking up exposures off the discard pile.
The layout has been refined over decades. It looks dense the first time you see it. After a season of play, it becomes familiar.
The NMJL card on a sticky note
- NMJL = National Mah Jongg League, founded 1937 in New York. Governing body for American mahjong.
- Membership in the hundreds of thousands. New card released every April.
- $15 per card, ordered via the NMJL website. Large-print version available at the same price.
- 2026 card has 55 hands across 9 sections.
- Card changes annually to keep the game fresh, prevent memorization, and rotate hand difficulty.
- Old card is still useful for practice, transitional play, and teaching beginners core concepts.
- Other organizations (The Big Card, Mahjong Press, American Mahjong Society) publish their own cards. The NMJL is the standard.
What the yearly card actually means for you
If you're new to American mahjong, the yearly card change can feel like a moving target. Just when you think you've started to understand the hands, a new card arrives and you're back at the beginning. I want to reframe that for you.
The card change is the game. It's not an obstacle to learning. It's the thing that keeps the game alive for players who've been at this for 20 years and players who picked up tiles for the first time last month. Every April, every player at every level resets together. There's no "behind" right now. There's just everyone, looking at the same new sheet, figuring out what's there.
Your strategy with a new card shouldn't be "memorize all 55 hands by May." It should be "learn the sections that show up most at your table, identify the hands that match how you like to play, and add to your repertoire over the course of the year." That's how the players who feel confident fastest actually work. They don't memorize the card. They read the card and decide what to play.
If you've been nodding along to this and want a structured way to actually learn the current card instead of feeling overwhelmed by it, the 2026 Strategy Edit is what I built for exactly that. It's a deep-dive guide to the 2026 card with hand-by-hand strategy, the parentheticals decoded, and the flexibility math worked out for you. It's a one-time purchase and it'll save you a season of trial and error.
If you want a community where the card is the conversation all year long, the Confidence Club is where I show up every week to teach, answer questions, and run challenges around the current card. It's $19.99/month, and the people inside it are the reason new card season feels like an event instead of a stressor.
If you're a brand new player and the rest of this is still abstract, start here. If you want to understand how to read the card before you commit to any product, the how to read the NMJL card guide is the natural next read. If you want to look up a term from this post, the mahjong glossary has every definition in one place. And if you want to see which hands give you the most flexibility on the current card, check the easiest hands on the 2026 card post.
The NMJL card has been a yearly ritual for almost 90 years. Every April, a new card. Every April, a new chance to learn the game again. That's the deal. Lean into it.
See you at the table.
