Local yaku

Local yaku are turned off in ranked matches, but they are turned on in some alternative game modes, and they can optionally be turned on in friendly matches and tournaments. It is not possible to pick and choose local yaku, so they are either all turned on or all turned off.

Riichi City recognizes more local yaku than Mahjong Soul. It includes toipuutao, akadora sanshoku, sanshoku tsuukan, as well as 11 additional yakuman not recognized in Mahjong Soul. However, Riichi City's local yaku do not include iipin moyue and chuupin raoyui.
