Examples

Toitoi 「対々」 is a standard yaku. In English, it is referred as "all triplets". That's due in part with every meld be composed of triplets. This yaku is not affected by kuisagari, where the hand is devalued in terms of han while open.

If this hand wins by tsumo, then it counts for the suuankou yakuman. Otherwise, it's a toi toi mixed with sanankou.

Formation

As the name implies, this yaku requires koutsu. Usually, this yaku is called open due to the ability for pon to claim discarded tiles from any player.
