A '''[[yaku]]''' {{kana|役}} is a certain pattern in a mahjong hand, or a special condition under which a win is declared. Many yaku are pattern-based yaku comparable to "poker hands". Unlike poker, yaku types do not supercede each other. Instead, they are the main factor to determine hand values.  Players must finish hands before others do; and each yaku has [[han|specific values]] attached to them to determine [[Scoring table|payment amounts]].
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]].


The yaku and their values are essential for [[scoring]]. The game rules define twenty-six different yaku, worth a different amount of '''[[han]]''' {{kana|飜}} based on their difficulty or pre-assigned value. A player can incorporate [[Yaku compatibility|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 addition, eleven additional patterns are classed as [[yakuman]].  Finally, 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.


'''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.
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 a very easy yaku to achieve. A new player may find it easiest to avoid opening their hand and simply aim for riichi every time; no other yaku is required to win the hand. However, this strategy is far too simple for serious play and an experienced player should generally aim for a high-scoring yaku or combination of yaku from the beginning of the hand.
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.

Example hand, containing many yaku.

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.

One han closed only

Menzenchin tsumohou
「門前清自摸和」
Win by self-draw
Closed only
 Any closed hand that wins by self-draw scores this yaku.
Riichi
「立直」
Ready hand

 Any closed hand that reaches tenpai may declare "riichi" to score this yaku. Declaring riichi requires you to bet 1000 points, and announces you are in tenpai.

「一発」
One shot
Closed only
 Declare riichi, then win by your next tile draw. In addition, no player can make tile calls between the riichi call and the win.
Pinfu
「平和」
All sequences
Closed only
 A closed hand that scores no fu from its composition at tenpai. This requires the hand to have:
  • All sequences.
  • A pair that isn't yakuhai.
  • A ryanmen wait (open wait) at tenpai. A ryanmen is two consecutive, non-terminal, tiles waiting to complete a sequence.

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.

Nagashi mangan
「流し満貫」
Terminal honor discards
Closed only (May be open on variation)
 All the discards are terminals and/or honors. In addition, none of these discards were called by other players.

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.
