Formation
Of all the standard yaku, sankantsu is the most difficult and least frequent. Its rate of occurrence is comparable to that of some yakuman.
As the name implies, the hand must call kan three times before the end of the hand. Naturally, the hand must also be tenpai to even be able to score.
Compatability
^ Ippatsu requires riichi to be of any use.

No sequential based yaku can combine with sankansu. This rules out pinfu, iipeikou, ittsu, and sanshoku doujun. Chiitoitsu is incompatible due to its usage of pairs.
Value
This yaku is set at 2 han. However, the number of kans significantly increases the hand's value. Generally, a fu count of 60 or more is the equivalent of increasing the han count by 1, in terms of scoring.
