Win great prizes — including an Automatic Mahjong Table!

American (NMJL) Play

The competition includes 12 games played over four rounds. Scoring is based on the NMJL card, with extra points awarded for jokerless hands and winning by selecting your final tile, and points taken away for discarding a tile used for another’s mahjong.

Like-skilled players are matched with one another, and players move between tables every round.
