What Is a Dead Hand in American Mahjong?

A dead hand is a hand that can no longer be completed into a legal winning hand. Once a hand is declared dead, that player stays seated but stops drawing and discarding for the rest of the round — and still pays the winner at the end. (Another player has to declare a hand dead; you can't call your own.)

What makes a hand dead

• Exposing a group that doesn't match any hand on this year's card
• Holding the wrong number of tiles (too many or too few)
• Calling for a tile you can't legally use in any card hand
• Exposures that no longer fit a single hand once you've changed direction
• Using a Joker illegally — for example, in a pair

How to avoid it

Before you call a tile and expose a group, make sure that group actually appears in a hand on the card — and that you can still complete the rest of that hand. Count your tiles when in doubt: you should have 13 (14 on your turn). The safest habit is to commit to a target hand and check every exposure against it.

Reading the card fluently is the real cure. Once you can scan a hand and know instantly whether your tiles fit, dead hands almost never happen.
