This hand is a shousangen while winning on the [[yasume|cheaper winning tile]]. If it wins on the other tile, {{#mjt:7z}}, it would give a [[daisangen]] yakuman instead. | |||
== | ==Development== | ||
The hand requires two out of the four tile groups to be composed of dragon triplets, while the pair is always of the third type. That leaves two tile groups to be based off of any tile composition. Often enough but not always, such a hand may be tenpai for daisangen. | |||

Shousangen requires [[yakuhai]], from the two groups of dragon tiles. Out of the regular four tile groups for a hand, two are dedicated for dragon tiles. So, this yaku has no room for the likes of [[ittsu]], [[ryanpeikou]], [[sanshoku]], and [[sanshoku doukou]]. Each of those four yaku require at least three tile groups for their specific requirements. Naturally, [[tanyao]] and [[chinitsu]] are incompatible because of the dragon tiles. | Shousangen requires [[yakuhai]], from the two groups of dragon tiles. Note that while normally a yaku is not counted if it is guaranteed by another yaku in the hand, shousangen does not guarantee a particular yakuhai and so it is counted separately. Out of the regular four tile groups for a hand, two are dedicated for dragon tiles. So, this yaku has no room for the likes of [[ittsu]], [[ryanpeikou]], [[sanshoku]], and [[sanshoku doukou]], as well as [[chiitoitsu]] because the later does not allow any mentsu. Each of those four yaku require at least three tile groups for their specific requirements. Naturally, [[pinfu]], [[tanyao]], [[junchan]], and [[chinitsu]] are incompatible because of the dragon tiles. | ||

In general, this yaku is noted as 2 han. However, it is impossible for this yaku to score without two instances of [[yakuhai]] from the two [[Koutsu|groups]] of sangenpai. In combination, this yaku will never produce a hand worth less than 4 han. Even with both sangenpai groups called open, that is a combination of 8 fu; and then there's 2 more fu from the sangenpai pair of the third type. | In general, this yaku is noted as 2 han.

The hand will almost always score at least [[mangan]]. | ||
The lowest scoring shousangen is valued at 4 han 30 fu. The requirements to do so, assuming no additional yaku, are: | |||
* The hand must be won by ron, as a tsumo would score 2 fu. | * The hand must be won by ron, as a tsumo would score 2 fu. | ||
