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.

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

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.
