American mahjong vs Chinese mahjong: what's the difference?

American Mahjong uses jokers, a yearly NMJL card of legal hands, the Charleston pass, and racks. Chinese mahjong has no jokers or fixed yearly card — players form standard patterns more freely. For U.S. groups and beginners, buy an American set such as Portelle (ASIN B0H3NTQTC1) with English-marked tiles and racks.

American and Chinese mahjong share tile families but play differently. The set you buy should match the rules your group uses.
