Can you make a Joker exchange to call mahjong? And does that count as self-picked?
Yes to both! This is one of those mahjong rules that can feel a little confusing until you see it played out.
Let’s say you’re one tile away from mahjong, and a joker would complete your hand. You draw a seven dot from the wall. Another player has an exposed group of seven dots with a joker in it, so you exchange your seven dot for that exposed joker.
That joker completes your hand, and you declare mahjong!
Even though you received the joker from another player’s exposure, this is still a self-picked mahjong. You drew from the wall and made a joker exchange during your turn to complete your winning hand.
So, how does the scoring work?
Each of the other three players pays you double the value printed on the card for your hand. If you’re playing a hand worth 25 points, each player pays you 50.
The player whose Joker you exchanged does not owe an additional payment. Giving up an exposed joker in a legal joker exchange is different from throwing the discard someone calls for mahjong.
And one more detail: if you need that joker exchange to complete your hand, your winning hand is not jokerless. The joker you just redeemed is part of your mahjong, so there is no jokerless bonus.
When you’re learning how to play American mahjong, understanding joker swaps, exposures, and self-picked mahjong helps you feel more confident about both declaring your win and scoring it correctly.
