What Is American Mahjong?

American Mahjong is a four-player tile game that blends:

• Pattern recognition

• Memory
• Social play

While Mahjong originated in China over 150 years ago, American players created a unique format that includes:

✔ Jokers
✔ The annual NMJL card

About Connor

“I thought Mahjong was slow and confusing — until I played my first competitive hand and realized how deep it really goes.”

Connor is a lifelong strategy gamer who fell in love with Mahjong after playing across Asia and online. After hundreds of games across American, Chinese, Hong Kong, and Riichi styles, he realized most beginners quit too early — simply because no one explained it clearly.

This site exists to fix that.
