Sankantsu (三槓子) is a standard yaku. This yaku requires kan to be called three times by one player. Due to this requirement, this yaku is actually the most difficult of the regular yaku. Within Tenhou.net, the yaku actually occurs less frequently than some yakuman.

Development
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, kan must be called three times before the end of the hand. A fourth kan converts the hand to the yakuman, suukantsu.
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.
Pitfalls
Sankantsu's difficulty stems from its various pitfalls during hand development. For starters, attaining the tiles necessary to call kan three times is difficult onto itself. In order to call kan in the first place, a player has to draw three out of the four tiles.
Value
This yaku is set at 2 han. However, the number of kans significantly increases the hand's value. Even with the minimum 3 kan of simples, they generate a fu count of 8 fu each, for a total of 24 additional fu to the base 20. So, at a minimum, this yaku is valued at 2 han and 50 fu, which is the equivalent of 3 han and 25 fu.
