Revision as of 05:27, 11 August 2013

A yaku is a certain pattern in a mahjong hand, or a special condition under which a win is declared.

A player requires at least one yaku to declare a win.

The game rules define lots of different yaku, worth a different amount of han based on their difficulty. A player can incorporate several different yaku in the same hand and add their han values for high-scoring hands.

Dora are not considered yaku, even though they provide han. A hand having no yaku may not win, even if it has multiple dora.
