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.
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 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]].
'''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.

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
Closed only
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.
Ippatsu
「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.
Agari: or
Iipeikou
「一盃口」
Identical sequences
Closed only
A hand with two identical sequences.


One han

May be open
Win with a tile from the dead wall - i.e., win by the tile drawn after a kan.

May be open
Win with a tile used for an opponent's added kan. Essentially, the tile needed to complete a kan is stolen to complete a winning hand.
Tanyao
「断幺九」
All simples
May be open (Closed only on variation)
A hand composed of only tiles that are numbered from 2-8. (In other words, a hand with no 1's, 9's, or honors.)
Agari: or
Yakuhai
「役牌」
Value tiles
May be open
A hand with at least one group of dragon tiles, seat wind, or round wind tiles. Each group is worth 1 han.

May be open (Loses 1 han)
Have sequences of "123", "456", and "789", all of the same suit, appearing as "123456789". Simply having every tile from 1-9 is not enough; the hand must have those exact sequences.
Toitoi
「対々」
All triplets
May be open
The entire hand is composed of triplets (and/or quads).
Agari: or
Sanankou
「三暗刻」
Three closed triplets

Three colored triplets
May be open
Three groups of triplets (and/or quads) with the same number.
Agari:

Agari:
Honroutou
「混老頭」
Terminals and honors
May be open (Consider as 4 han †)
Every tile is either a terminal or an honor tile.
† This hand may be considered as 4 han, because it is impossible to score this hand without either chiitoitsu or toitoi.
Agari: or
Shousangen
「小三元」
Small three dragons

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.


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.
