Sanshoku doujun 「三色同順」 is a yaku scored when a hand has three sequences, one of each suit, that share the same numbers. The shorthand sanshoku more commonly refers to this yaku, instead of the significantly more difficult to achieve sanshoku doukou. It is sometimes called sanshiki 「さんしき」 in older media.

Tile pattern

Agari :

This hand contains a "123" sequence in each of the 3 numbered suits, scoring this yaku. Since this is a closed hand, sanshoku is worth 2 han.

Agari :

Agari : or

While having same tiles with the first example, these hands were opened, so sanshoku is only valued at 1 han.

Compatibility

^ Ippatsu requires riichi to be of any use.

Sanshoku requires three sequences, so it is incompatible with toitoi, sanshoku doukou, sanankou, sankantsu, shousangen, honroutou, and chiitoitsu. It requires three suits, so it is also incompatible with honitsu and chinitsu. Finally, sanshoku leaves no room to also score ryanpeikou or ittsu.

Takame and yasume

Main article: Takame and yasume

Sanshoku is particularly affected by takame and yasume. When a hand has a ryanmen wait, and is waiting to complete the 3rd sequence needed for the sanshoku pattern, only one of the two winning tiles will produce sanshoku.

Agari: or

Only the 6-pin produces sanshoku in this case.

Versus ittsu

Main article: Ittsu vs sanshoku

Both ittsu and sanshoku are apparent.

Before reaching tenpai, it is possible for a hand to develop into both ittsu and sanshoku. However, there is no room for both yaku to exist. When both yaku are possible, then players will eventually need to decide which one to aim for.

Value

This yaku is subject to kuisagari. When closed, the yaku is worth 2 hand, but it is reduced to 1 han when open.

-Sanshoku is particularly affected by [[takame and yasume]].  At times, the tile wait involves a ryanmen looking for two tile types for the third tile grouping needed for this yaku.  In this case, one may result in sanshoku, while the other does not; and the difference here may involve 1 or 2 han.
