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.

Sanshoku doukou is incompatible with any yaku requiring more than one sequence, namely [[pinfu]], [[iipeikou]], [[ittsuu]], [[sanshoku doujun]], and [[ryanpeikou]]. It cannot be combined with [[honitsu]] and [[chinitsu]], which require tiles of a single suit. [[Chiitoitsu]] requires seven pars, which precludes the triplets for sanshoku doukou. Finally, [[shousangen]]'s two dragon triplets do not leave enough room for the three triplets of suited tiles required.
