'''Suuankou''' {{kana|四暗刻}}, literally "four [[ankou]]", is a [[yakuman]] scored when a hand has four closed triplets and a pair. | '''Suuankou''' {{kana|四暗刻}}, literally "four [[ankou|closed triplets]]", is a [[yakuman]] scored when a hand has four closed triplets and a pair. | ||
If the hand is on a [[shanpon]] wait (two pairs waiting to complete a triplet), the winning tile must be a [[tsumo|self-draw]] and not a [[ron|discard]] from another player. | If the hand is on a [[shanpon]] wait (two pairs waiting to complete a triplet), the winning tile must be a [[tsumo|self-draw]] ([[tsumo]]) and not a [[ron|discard]] from another player ([[ron]]). While ron does not open the hand, it does open the resulting ''triplet'', which means the 4th triplet is not closed, invalidating the yakuman. | ||
'''Suuankou tanki''' {{kana|四暗刻単騎}} is | '''Suuankou tanki''' {{kana|四暗刻単騎}} is scored when the hand is on a [[tanki]] [[wait]], i.e. it has completed the four triplets by tenpai. The hand may win from another player's discard, counting for a yakuman. A hand of this pattern may count [[Multiple yakuman|double yakuman]], as an added [[Yaku variations#Multiple_yakuman|variation]]. | ||
Regardless of the wait, suuankou must be scored with a [[closed]] hand; none of the triplets can be called from other players' discards. An "all triplet" hand with open calls would then either count for [[toitoi]], [[sanankou]], or both. | |||

All four of the ''triplets'' must be concealed for this hand to be counted as yakuman. As mentioned above, if a triplet is completed via ron, then the triplet is not considered concealed. Therefore, if the hand has a [[shanpon]] wait, it can only win by tsumo. [[Kan|Closed kan]]s are acceptable, as kans are considered triplets. Of course, calling [[pon]] automatically invalidates the yakuman. | All four of the ''triplets'' must be concealed for this hand to be counted as yakuman.

Suuankou is one of the three '''yakuman gosanke''' {{kana|役満御三家}}, or "the three big families of yakuman", along with [[kokushi musou]] and [[daisangen]]. These are the three most common yakuman in the game. Suuankou itself is the most common yakuman in 4-player, likely because it can be formed from any type of tile. The difficulty of this yakuman stems from the need to draw at least 3 out of 4 of a single tile type, for four different tile types. | |||
