Suuankou
Suu ankou is one of the standard yakuman hands. This hand consists of four concealed triplets and a pair, i.e. none of the triplets must have been claimed from other players' discards. Depending on the wait, this hand may be worth one yakuman or two: If the hand is on a shanpon wait, the winning tile must be a tsumo and not a discard of another player, and the hand is worth one yakuman; if the hand is on a tanki wait, the winning tile may come from another player's discard, and the hand is worth two yakuman. This hand is closed only.
