Sanshoku doukou (三色同刻) is a standard yaku. This yaku involves koutsu (triplets) of the same numbered tiles across the three main suits.
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 koutsu 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.

Note: This hand is also waiting for , but that would not give sanshoku doukou.
Formation
This yaku is actually a fairly difficult yaku to complete. For every number across the three different suits, there are only 12 tiles. A sanshoku douko hand has to have 9 of the 12 tiles of one number. The 3 tiles of that number not in the hand has to be one of each suit, which yields pretty bad odds.
Compatability
Value
Whether open or closed, this yaku remains at 2 han.
