Rinshan kaihou

Rinshan kaihou (嶺上開花) is a standard yaku, where a player wins with the rinshanpai, i.e., the replacement tile after forming a kantsu. As such, this yaku is only accessible via kan calls.

Setting up rinshan kaihou

Like any hand, this yaku requires tenpai to even have a chance of winning. This is particularly true when kan is involved. As such, the fourth tile for kan counts as an extra tile. If that tile is in the hand, it actually takes up one tile space, that could be used for normal hand development.

Rinshan kaihou and haitei

Rinshan kaihou cannot be combined with haitei, a yaku for calling tsumo on the final tile from the live wall. When winning on the replacement tile after a kan, tsumo is not called on any tile from the live wall, but on a tile from the dead wall.

Combines with

• Almost any other yaku
• Not with any yakuman, scorewise. Though, yakuman may be completed via the rinshanpai.
