Revision as of 20:32, 2 September 2015

Example hand, containing many yaku.

A yaku 「役」 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, players must finish hands before others do; and each yaku has specific values attached to them to determine payment amounts.

The yaku and their values are essential for scoring. The game rules define lots of different yaku, worth a different amount of han 「飜」 based on their difficulty or pre-assigned value. A player can incorporate several different yaku in the same hand and accumulate 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. So, as an early part of the game's learning process, it is essential to learn the different yaku listed here and eventually their han values.

One han closed only

Closed only

Optional

The above list is generally considered as the "standard yaku", including the yakuman. However, the game offers an even larger array of tile patterns. Various house rules may opt to use some of these yaku on their own.
