A '''[[yaku]]''' {{kana|役}} is a certain pattern in a mahjong hand that scores points, and a necessary condition for winning. They are analogous to hands in poker. Unlike poker, multiple yaku can be combined into one hand. Under standard rules, there are 26 different yaku and 11 [[yakuman]] (a special class of high-scoring yaku). In addition, one special case may be allowed in [[nagashi mangan]]. | |||
'''In order to win any hand, the hand must have at least one yaku.''' Even if a hand has [[dora]], it cannot score without a yaku. Declaring a win without yaku can score a [[chombo]] penalty. Therefore, when learning the game, it is essential to learn the different types of yaku. | |||
Each yaku has a specified amount of '''[[han]]''' {{kana|飜}}, generally based on their rarity. You can also increase the hand's han count with [[dora]], but this does not count as a yaku. A hand's total han value, counted from adding up yaku and dora, [[Scoring table|determines the points]] you'll get in the end. | |||
The most important yaku to learn is [[riichi]], since it is very common and very easy to achieve. A new player may find it easiest to never [[naki|open]] their hand, always calling riichi, and get a few wins. However, this strategy is far too simple for serious play; a variety of yaku should be employed. | |||

Revision as of 18:18, 22 March 2024
A yaku 「役」 is a certain pattern in a mahjong hand that scores points, and a necessary condition for winning. They are analogous to hands in poker. Unlike poker, multiple yaku can be combined into one hand. Under standard rules, there are 26 different yaku and 11 yakuman (a special class of high-scoring yaku). In addition, one special case may be allowed in nagashi mangan.
In order to win any hand, the hand must have at least one yaku. Even if a hand has dora, it cannot score without a yaku. Declaring a win without yaku can score a chombo penalty. Therefore, when learning the game, it is essential to learn the different types of yaku.
Each yaku has a specified amount of han 「飜」, generally based on their rarity. You can also increase the hand's han count with dora, but this does not count as a yaku. A hand's total han value, counted from adding up yaku and dora, determines the points you'll get in the end.
The most important yaku to learn is riichi, since it is very common and very easy to achieve. A new player may find it easiest to never open their hand, always calling riichi, and get a few wins. However, this strategy is far too simple for serious play; a variety of yaku should be employed.

The non-dealer hand is a winning hand with the first tile draw. | |
Special case
This yaku does not specifically deal with a player's hand, but rather the player's discards. In addition, the hand may or may not be at tenpai upon scoring. The result of nagashi mangan modifies the case of ryuukyoku, where point exchanges equate to mangan.

All the discards are terminals and/or honors. In addition, none of these discards were called by other players. | |
Local
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.
