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.

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. In terms of frequency, games do not involve calls for kan all that often, let alone more than one instance in a hand. Even when someone is tenpai for sankantsu, the hand can end in the event another player calls kan for a fourth time, invoking an [[abortive draw]]. | ||

This yaku is set at 2 [[han]]. However, the number of kans significantly increases the hand's value. Even with the minimum 3 open kan of [[tanyao|simples]], they generate a [[fu|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 [[Scoring table|2 han and 50 fu]], which is the equivalent of [[Scoring table|3 han and 25 fu]]. | This yaku is set at 2 [[han]].

Even with a base of 2 han, the number of kan calls adds the probability of additional dora, which may have an immediate impact on the hand value. Just one dora and adequate fu may bump the hand already into mangan. If any of the tiles used for kan became dora, that's instantly 4 dora. | |||
