Sanshoku doukou 「三色同刻」 is a yaku scored when a hand has triplets (and/or kans) of the same numbered tile in all three suits. Whether open or closed, this yaku scores 2 han.
Tile pattern cases
For this sanshoku doukou there are cases where the yaku is guaranteed and cases where it is not.
Case where sanshoku doukou is guaranteed
Agari: 
or 
Here, all three triplets of number three are already on the hand, and sanshoku doukou is guaranteed for both tiles waited on.
Case where sanshoku doukou is not guaranteed
Agari:
Note: This hand is also waiting for , but that would not give sanshoku doukou.
Agari:

Formation
This yaku is difficult to complete. There are 12 tiles per number, 4 tiles per suit. Sanshoku doukou requires 9 of those 12 tiles, and 3 of each suit, which yields pretty bad odds. In addition, unlike daisangen, there is no compensation if you only end up having 1-2 triplets, so calling to complete triplets is harder.

Sanshoku doukou requires three of the four tile groups to be triplets. Thus, it is incompatible with any yaku that requires more than one sequence, including iipeikou, ittsuu, sanshoku doujun, and ryanpeikou. There also isn't enough room for shousangen's two dragon triplets. Finally, pinfu and chiitoitsu forbid triplets.
