American vs Chinese mahjong sets: how to tell them apart
The short answer: count the jokers. American sets have them, Chinese sets do not, and you cannot play American mahjong without at least eight.
Checked and updated October 31, 2026
The differences that matter
| American set | Chinese set | |
|---|---|---|
| Total tiles | Usually 160 or 166 | Usually 144 to 148 |
| Jokers | 8 to 10 | None |
| Racks with pushers | Usually included in starter sets | Usually not included |
| Numbers on tiles | Usually Western numerals and letters in the corner | Often Chinese characters only |
| Playable rules | American, and Chinese if you set the jokers aside | Chinese only |
For example, one retailer's 148-tile Chinese set has no jokers and puts Western numerals only on its flower tiles; the retailer itself says it is not compatible with American rules (see the listing details). Its American sets of 166 tiles include 10 jokers and Western letters and numerals on every tile.
How to check a listing
- Search the description for "joker". No jokers, no American play.
- Check the tile count. Under 152 is not enough.
- Look for the words "American", "Western" or "NMJL". "Traditional" or "Chinese" usually means no jokers.
- Check whether racks and pushers are included or sold separately.
Or use the set checker to get a yes or no in three questions.
Already bought a Chinese set?
It may be possible to convert it. Joker stickers are sold for exactly this, and players stick them onto blank tiles to make jokers. The catch is numbers: you need 8 jokers, and many Chinese sets come with only about 4 blanks, so you may have to buy extra blank tiles that match your set's size. You will also need racks if your set did not include them. If that adds up to more than a starter American set, buying the right set is simpler.
