What is the NMJL card (and do you need one)?
The NMJL card is the annual card published by the National Mah Jongg League. It lists the legal winning hands for American mahjong for that year, and it is the rulebook most US clubs and tournaments play by.
What the card actually does
Unlike some mahjong styles with fixed scoring, American mahjong refreshes its valid hands every year. The card lays out those hands — with their point values and required tile combinations — so players know what to aim for. Without it, you cannot reliably play by NMJL rules.
Why it is sold separately
The card is updated annually and licensed by the League, so it is never bundled inside a tile set. Our complete sets and product FAQs state clearly that the official card is a separate purchase. To keep one protected and readable all season, pair it with our NMJL card holder & protector.
Do you need it?
If you are joining a US club, class or tournament, yes — get the current year’s card. Casual home play among friends can skip it, but most organized American games expect every player to have the same edition on the table.
Stocking the card holder for resale? It is a low-cost, year-round seller — see the wholesale programme or request a quote.
Frequently Asked Questions
Is the NMJL card included with a mahjong set?
No. The official National Mah Jongg League card is published anew every year and is sold separately. Our sets list it as a separate item so buyers know to order it.
Why does the card change every year?
The League refreshes the legal winning hands annually to keep play varied. A 2026 card will not match 2025 hands, so players typically buy the current year’s edition.
Do I need the card to play at all?
If you play by NMJL rules — the dominant style in US clubs and tournaments — yes, the card defines which hands are valid that year. Casual free-play without the card is possible, but league and club games use it.
