Shousuushii

Conditions

• The hand must contain triplets (or kans) of three different wind tiles (any three of East, South, West, North)
• The fourth wind must be used as the hand’s pair
• The remaining meld can be any valid meld (sequence or triplet)
• The hand can be open — calling pon on wind tiles is allowed
• This is considered a yakuman in standard Riichi rules

Strategy Tips

• Shousuushii requires heavy investment in wind tiles. If your starting hand contains two wind pairs and a wind triplet, it is worth considering, but be realistic about collecting a third wind triplet when each wind has only four tiles total.
• Because the fourth wind is used as the pair rather than a triplet, shousuushii is somewhat more achievable than daisuushii. If you are pursuing daisuushii and realize the fourth wind triplet is unlikely, you can pivot to shousuushii by keeping that wind as your pair instead.
• Opponents who see you with two or three open wind triplets will recognize the danger. They will hold wind tiles tightly, so try to collect as many winds as possible before revealing your intent through open calls.
