Win on the replacement tile drawn after declaring a kan.
How Rinshan Kaihou (嶺上開花) works
Completing the hand on the replacement tile drawn from the dead wall right after declaring a kan — a flower blooming on the ridge.
Rinshan Kaihou triggers when the tile you draw to replace a kan is itself your winning tile, completing the hand by tsumo. It can only occur immediately following a kan declaration and counts as a self-draw win. It pairs naturally with the kan-heavy hands like sankantsu and toitoi, and stacks with most other yaku.
Good to know
- •Counts as a tsumo, so it combines with menzen tsumo when the hand is otherwise concealed.
- •Both open and closed kans can trigger it, since the replacement draw follows either.
- •It is incompatible with haitei because the winning tile comes from the dead wall, not the last live tile.
Rinshan Kaihou (嶺上開花) — FAQ
Does declaring a kan guarantee rinshan?
No. The replacement tile must actually complete your hand; otherwise you simply continue play normally.
Can rinshan stack with menzen tsumo?
Yes, provided the hand is fully concealed. Rinshan is a self-draw, so a closed hand also earns the tsumo yaku alongside it.
