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 that scores points, and a necessary condition for winning. They are analogous to hands in poker. In total, there are 26 yaku, 11 [[yakuman]] (a special class of high-scoring yaku), and 1 special case 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. Attempting to win without a yaku is subject to a [[chombo]] penalty, so it is important to learn the yaku, or at least the most common types.


'''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 is worth a specified amount of  '''[[han]]''', where rarer yaku are generally worth more. A hand can score multiple yaku at once. When a hand is won, its han (from both yaku and dora) are added up, and the total han value is converted into points using a [[scoring table]].


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: it is the most common yaku and very easy to achieve. Any hand that isn't open may declare riichi when [[tenpai|about to win]]. A beginner may rely solely on riichi, though it is important to learn the other yaku too.

Example hand, containing many yaku.

A yaku 「役」 is a certain pattern that scores points, and a necessary condition for winning. They are analogous to hands in poker. In total, there are 26 yaku, 11 yakuman (a special class of high-scoring yaku), and 1 special case 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. Attempting to win without a yaku is subject to a chombo penalty, so it is important to learn the yaku, or at least the most common types.

Each yaku is worth a specified amount of han, where rarer yaku are generally worth more. A hand can score multiple yaku at once. When a hand is won, its han (from both yaku and dora) are added up, and the total han value is converted into points using a scoring table.

The most important yaku to learn is riichi: it is the most common yaku and very easy to achieve. Any hand that isn't open may declare riichi when about to win. A beginner may rely solely on riichi, though it is important to learn the other yaku too.

Win by self-draw
Closed only
 Any closed hand that wins by self-draw scores this yaku.

Closed only
 A closed hand that scores no fu from its composition at tenpai. This requires the hand to have:
  • All sequences.

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.
