The short answer: An American mahjong set has 8 jokers, part of the full 152 tiles. A joker stands in for any tile except a flower and scores as the tile it replaces. Whether jokers must be exposed or can stay hidden depends on your house rules, and the yearly card spells out the details.
Jokers are the wild cards of American mahjong, and they’re the first thing new players ask about. Open any American set and you’ll find eight of them sitting in the tray next to the flowers. Once you know what they can do, the whole game changes.
What can jokers do in American mahjong?
- Replace any tile you need, from a dot to a dragon — never a flower.
- Count as the tile they stand in for, so a joker playing as a dragon scores like a real dragon.
- Fill a pung, kong, or pair when your hand is one tile short.
- Usually can’t be discarded once drawn — you keep it and use it.
What’s the difference between an exposed and a concealed joker?
- Exposed joker: you lay it on the table with your meld so everyone sees it. Most tables allow this freely.
- Concealed joker: you keep it hidden in your hand. Some groups ban this and make you declare every joker you hold.
- The yearly card and your club’s house rules decide which style you play, so ask before the first game starts.

Do other mahjong games use jokers?
Mostly no. Chinese, Hong Kong, and Riichi mahjong all play with zero jokers. Jokers are a signature of American mahjong, where the yearly card builds them in. A few Chinese house games use wild tiles, but that’s a house rule, not a standard.
Can two jokers form a pair?
Usually not. In most American rule sets, a pair needs at least one natural tile, and two jokers together don’t count. House rules love to tweak this detail, so check your group’s rule sheet before building your hand around it.
Why does the yearly card matter for jokers?
The yearly card changes which hands are legal and how useful jokers are for each one. Some years reward joker-heavy play, others barely touch them. Your set stays the same, but the strategy shifts every season.
