Shousuushii (小四喜)

13 han

Three wind triplets + a wind pair.

How Shousuushii (小四喜) works

Shousuushii (small four winds) is a yakuman with three wind triplets plus a pair of the fourth wind.

Three of the four winds form pungs or kans while the remaining wind forms the pair, leaving no room for any non-wind set besides the winds occupying three groups and the pair. It works open or closed. Promoting the fourth wind pair into a triplet instead yields daisuushii, the big four winds.

Good to know
  • Three winds are tripled and the fourth wind is paired.
  • Counts as a yakuman regardless of open or closed.
  • Completing the fourth wind as a triplet upgrades it to daisuushii (often a double yakuman).

Shousuushii (小四喜) — FAQ

What separates shousuushii from daisuushii?

Shousuushii has three wind triplets and a wind pair; daisuushii has all four winds as triplets and is typically scored as a double yakuman.

Can the pair be a non-wind tile?

No. The pair must be the fourth wind; otherwise the hand does not form the small four winds pattern.
