In American Mahjong, the official NMJL card is more than a reference — it’s the foundation of every game. The 2025 Mah Jongg Card lists all valid hands and scoring combinations for the year, ensuring every player follows the same rules.
Without it, games can become inconsistent or even confusing. Each year’s card introduces changes to keep the game challenging and fair. Even experienced players are surprised by new patterns and combinations, which means staying updated is essential.
Having your own card also speeds up play, reduces disputes, and makes it easier to track scoring. So if you’re serious about playing American Mahjong — whether in local meetups or competitive leagues — the 2025 card is a must-have.
