The NMJL Card is the rulebook for American Mahjong. It’s published every spring by the National Mah Jongg League, and the hands on it change every year — a hand that scores on one year’s card might not appear at all on the next. You cannot play American Mahjong without a copy of the current card. Our full Card overview covers the format, pricing, and release cadence in more detail.
This hub explains how the card works: the way it’s organized into categories, what the notation means (concealed vs. exposed, point values, joker rules), and how experienced players read it quickly at the table. We do not reproduce the League’s actual hand list here or anywhere on this site — that’s the League’s copyrighted work, and the only accurate, current copy is the one you buy directly from them. See how to buy the current-year card for pricing and sizing.
