How NMJL Scoring Works: Your Card, Explained
Every new player looks at their NMJL card the same way the first time: like it’s a wall of numbers in a font only a cryptographer could love. We promise you it isn’t. It’s just a map, and once you know how to read it, you’ll never see a jumble of numbers again — you’ll see your next hand.
Here’s what’s actually on the card, section by section.
The card is organized into sections, not random hands
Every year, the National Mah Jongg League publishes a new card divided into categories — things like the current year’s number, consecutive runs, odd numbers, even numbers, “like numbers” across suits, quints, winds and dragons, and singles and pairs. Each section groups hands that share a family resemblance, which makes the card far easier to scan once you know which section you’re hunting in.
Each printed hand is a sentence, once you know the alphabet
-
Numbers are printed in different colors specifically to show you which numbers need to come from different suits versus the same suit within one hand.
-
Letters stand in for tile types — F for Flower, D for Dragon, and N/E/W/S for the wind tiles.
-
Symbols and footnotes carry real weight. A hand marked to be played concealed means you can’t expose any sets by claiming discards until you’re ready to declare Mah Jongg. A note limiting or banning jokers is not a suggestion — it’s the rule for that specific hand only.
Jokers are the wild card, literally — except when they aren’t
Most hands allow jokers as substitutes for nearly any tile. But the Singles and Pairs section is the one place on the card where jokers are banned entirely, which is exactly why those hands are simple to picture and surprisingly hard to complete. It’s a good example of why reading the footnotes matters as much as reading the hand itself.
The value printed next to each hand is your built-in difficulty rating
Point or dollar values increase for harder patterns and hands that require you to stay concealed the whole game. If you’re comparing two possible hands mid-Charleston and aren’t sure which to build toward, the value on the card is quietly telling you which one is riskier to chase — and how well it pays off if you land it.
The card is not optional equipment. It’s the rulebook
A new card is released every year, and the previous year’s hands stop being legal the moment the new one arrives. That’s not a minor detail — it’s the entire reason American Mahjong stays fresh instead of becoming a game you memorize once and play on autopilot forever.
We include your own official NMJL card as part of every Beginner Series, and we always have extras on hand to borrow or buy in-studio if you show up card-less. Nobody plays without one at our tables — it’s simply the shared language everyone needs to be speaking.
Want the card to actually make sense instead of just sitting in your hands? That’s the whole point of our Beginner Series — four weeks, small groups, and an instructor walking you through your card section by section until it clicks.
