American Mahjong Card 2026: The National Mah Jongg League Card Explained

The American mahjong card — the National Mah Jongg League card — is the annual rulebook of legal hands. Learn what the 2026 American mahjong card is, how to read it, and why a new one comes out each year.

By Wei Liang · Founder & Production Lead, Mahjong Market

Every spring, American mahjong players wait for the same thing: the new NMJL card. The National Mah Jongg League refreshes its list of legal winning hands once a year, and the moment the 2026 card ships, every hand from the 2025 card is officially retired. The card is the one accessory that decides what you are actually allowed to build — so understanding it is non-negotiable. Below: what the card is, how to read it, and what changed in 2026.

What is the NMJL card?

The National Mah Jongg League card is the official annual reference of legal winning hands for American mahjong. Each year the league publishes a new card showing every authorized hand and its point value. Unlike Chinese mahjong, where players complete generic sets, American players must match a specific hand printed on the current card.

Think of it as the year’s “menu” of winning hands. You pick one and build toward it.

A brief history of the National Mah Jongg League

The NMJL was founded in 1937 by a group of American mahjong enthusiasts who wanted to standardize the game across the United States. At the time, American mahjong was played with wildly different rule sets depending on the region, which made it hard for players from different cities to sit at the same table. The league’s founders solved this by publishing a single, authoritative card of legal hands — and requiring that it be updated each year.

Over the decades, the NMJL grew into the governing authority for American mahjong. It now organizes tournaments, certifies instructors, publishes educational materials, and funds charitable causes through its annual card sales. When you buy a card, part of the proceeds supports the league’s nonprofit mission. The NMJL card has been the gold standard for over 85 years, and virtually every American mahjong club in the country plays by it.

Why a new card every year?

The league refreshes the hands annually to keep the game fresh and balanced. That means:

• The 2026 card is required for 2026 play.
• Last year’s card lists hands that are no longer valid.
• Serious groups replace their cards each spring.

The annual refresh is not just cosmetic. It prevents the game from becoming stale and ensures that no single hand or strategy becomes dominant year after year. Some hands are retired, some are tweaked, and new hands are introduced — keeping even experienced players on their toes.

How the annual card is designed

The process behind each new card is surprisingly rigorous. A committee of experienced players and league officials reviews data from the previous year — which hands were won most often, which were rarely attempted, and whether any hand gave an unfair advantage. The committee then:

1. Retires underplayed hands — patterns that almost nobody attempted are removed to free up space.
2. Adjusts overpowered hands — if a particular hand was won too frequently, its point value may be lowered or its tile requirements tightened.
3. Introduces new hands — fresh patterns are added to replace retired ones, often inspired by player suggestions submitted to the league throughout the year.
4. Tests for balance — new combinations are vetted to ensure they are achievable but not trivially easy, and that they interact well with existing hands.

The goal is always a card that rewards skill and adaptability, not just memorization of one dominant strategy.

How to read the card

The card groups hands into families, typically:

• Numbers — runs and pungs from the numbered suits.
• Winds / Dragons — honor tile combinations.
• Flowers — hands using flower/season tiles.
• Jokers — many hands allow joker wild substitutions.
• Clea / Singles / 356 — special named patterns with specific rules.

Each hand shows:

• The exact tile pattern
• Which suits/tiles are allowed
• Any joker limits
• The point value (used for “charity”/table stakes)

Reading the card efficiently is a skill in itself. New players often start by scanning the lower-value hands (easier to complete) and gradually work up to higher-point patterns as they gain confidence.

Card strategy: choosing your target hand

One of the most important decisions you make each game is which hand to pursue. The card lists dozens of options, but your choice should match your skill level and the tiles you draw.

Conservative vs aggressive approaches

• Conservative players tend to pick hands in the 25–30 point range. These hands are easier to complete, require fewer exotic tiles, and often have more joker slots. They won’t win the biggest payout, but they win more consistently — ideal for beginners and players who prefer steady results.
• Aggressive players chase 50+ point hands. These pay out big when they hit, but they require specific tiles, have fewer joker allowances, and are harder to defend against opponents who may be discarding tiles you need. Aggressive play is rewarding but riskier — one dead draw can end your game.

X hands vs single-suit hands

• X hands (also called “cross-suit” hands) use tiles from two or three suits. They are more flexible because you can pivot between suits if one direction stalls. However, they often require more exact tile combinations.
• Single-suit hands focus on one suit only (Bams, Craks, or Dots). They are narrower but sometimes easier to build because you only need tiles from one category. The trade-off is less flexibility — if your suit is being hoarded by opponents, you may have no backup plan.

A good intermediate strategy is to pick two candidate hands early in the game: one conservative backup and one aggressive target. As the draw progresses, commit to whichever one your tiles are naturally building toward.

Year-over-year card trends

If you compare cards from different years, you will notice patterns in how the league evolves the game:

• Joker-friendly hands have increased — more hands now allow joker substitutions, making the game slightly more accessible to newer players while still rewarding veterans who complete hands without jokers (for higher value).
• Flowers and special hands rotate frequently — these categories see the most change each year, which keeps the “fun” hands unpredictable.
• Point values have gradually crept up — the highest-value hands now reach higher point totals than in decades past, reflecting the league’s effort to reward increasingly skilled play.
• Singles and pairs hands have diversified — there are more options for hands built on single tiles or pairs, giving players who prefer a lighter, faster style more choices.

Card variants and alternatives

While the official NMJL card is required for sanctioned play, some casual groups use alternatives:

• Homemade hand lists — social groups sometimes create their own hand lists for fun, adding house rules or custom patterns. These are fine for casual play but are not recognized in any official setting.
• Previous-year cards — some informal circles continue to play with last year’s card out of convenience. Be aware that this means you are playing with retired hands, which can confuse new players who are learning from the current card.
• Digital card apps — several apps now display the current NMJL card on your phone. These are convenient for practice and reference, but most tournaments and clubs still require the physical laminated card at the table.

If you are playing in any NMJL-registered club or tournament, only the current-year physical card is acceptable. No substitutes.

Tournament and official competition rules

In NMJL-sanctioned tournaments, the card rules are strict:

• Every player must have access to the current-year card at the table.
• A winning hand is verified by the card — if your tiles do not match a listed hand exactly, the win is invalid.
• Joker substitution limits listed on the card are enforced. Using too many jokers in a hand that restricts them disqualifies the win.
• Some tournaments require that each player hold their own card rather than sharing a single table copy, to prevent disputes over which hand a player was pursuing.

If you are organizing a tournament or club night, make sure every table has at least one current card. Stock extras — they are small, affordable, and essential.

How to use it in a game

1. Before play, each player picks a target hand from the card.
2. Draw and discard to build toward that hand.
3. When your 14 tiles match the pattern exactly, call Mahjong!
4. The table checks your hand against the card to confirm it is legal.

One per table — or one per player?

Standard etiquette is one card per table so everyone can see allowed hands, though many players keep their own. The 2026 card is laminated and spill-resistant, built for the table.

In tournament settings, one per player is preferred so each person can privately study their options without leaning over a shared card.

Pair it with the right set

The card only works with a proper 166-tile American set (including jokers and flowers). If you don’t have one yet, start with a complete set and add a quiet mat and pushers.

The one thing to remember

The NMJL card is not optional for standard American play — it is the rulebook. Get the 2026 card, pair it with a complete set, and you are playing by the book.
