Why the NMJL Card Matters
Defines Valid Hands
The card lists every legal winning hand. If your hand isn't on the card, it doesn't count. No exceptions.
Changes Every Year
A new card releases each spring with different hands. This keeps the game fresh and interesting year after year.
Affordable Essential
At ~$14, it's the most affordable piece of equipment you'll need. Every player should have their own copy.
