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. While ron does not open the hand, it does open the resulting ''triplet'', thus invalidating the yakuman. | 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.

The hand in this state may win from another player's discard, and it still counts as a yakuman. In this case, all four triplets are present in the hand. A hand of this pattern may count [[Multiple yakuman|double yakuman]], as an added [[Yaku variations#Multiple_yakuman|variation]]. | ||
For either type of suuankou, either the shanpon or the tanki variety, the hand itself must be closed only in order to count for yakuman. So, none of the triplets must have been claimed from other players' discards. An "all triplet" hand with open calls would then either count for [[toi toi]], [[sanankou]], or both. | For either type of suuankou, either the shanpon or the tanki variety, the hand itself must be closed only in order to count for yakuman.

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.

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. Of all the yakuman, suuankou is the most common. This is likely because it can be formed from any type of tile. | |||
