List of yaku: Difference between revisions

A '''[[yaku]]''' is a certain pattern in a mahjong hand, or a special condition under which a win is declared.  The yaku are comparable to "poker hands".  They each have patterns, and they each have identifiable names.  Unlike poker, yaku types do not trump each other.  Instead, each yaku has [[han|specific values]] attached to them.

The yaku and their values are essential for [[scoring]].  The game rules define lots of different yaku, worth a different amount of [[han]] based on their difficulty. A player can incorporate [[Yaku compatability|several different yaku in the same hand]] and add their han values for high-scoring hands.  For additional scoring, the game also features [[dora]].  However, possession of dora are not considered as yaku, even though they provide han. '''In order to win any hand in this game, a player requires at least one yaku.'''  A hand having no yaku may not win, even if it has multiple dora.  Declaring a win on a yakuless hand may result in [[chombo]].
