'''Suuankou''' {{kana|四暗刻}} is one of the standard [[List_of_yaku#Yakuman|yakuman]] hands. This hand consists of four concealed [[Mentsu#Ankou|triplets]] and a pair, i.e. none of the triplets must have been claimed from other players' discards.  If the hand is on a [[shanpon]] wait, the winning tile must be a tsumo and not as a discard of another player.  A win by discard may render the fourth triplet as an "open" triplet.  Thus, the condition for the yakuman would not be met.

Then there is '''suuankou tanki''' {{kana|四暗刻単騎}}, which features the hand with a [[tanki]] [[Machi|wait]], the winning tile may come from another player's discard.  In this case, all four triples are present in the hand.  This hand is closed only.

{{#mjt: 55666p11188s666z}} Winning tile: {{#mjt: 5p}} or {{#mjt: 8s}}.  

:''Note'': Either tile must be won by tsumo.  Otherwise, this hand is [[toitoi]] and [[sanankou]].

: ''Note'': This wait is sometimes considered to be worth [[multiple yakuman|double yakuman]].  Nevertheless, yakuman is guaranteed with the winning tile.

This hand is automatically a [[Scoring table|yakuman hand]], won by [[mentsumo|tsumo]] using a [[shanpon]] (tenpai holding two pairs) or any win if using a [[tanki]] (one tile waiting for a duplicate).  Variable rules may allow the tanki version to count double that of the yakuman points.

All four of the triplets must be concealed for this hand to be counted as a yakuman. [[Naki|Tile calls]] of [[kan|closed kans]] are acceptable, as the closed kan also counts as a closed triplet. 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.  [[Naki|Discard calling]] to attain tiles immediately removes any chance of forming this yakuman.
