Win on the replacement tile drawn immediately after declaring your own kong.
One tile away.
The winning hand
The gold outline marks the winning tile. Revealed sets are separated from concealed tiles.
The moment it comes together.
You have already voided the absent suit. You collected four matching tiles and declared a concealed kong. The replacement draw is 5 circle, completing your hand. Declare Hu on that replacement tile.
Compatible features can combine. The fan total is capped at four; a full score also depends on the winning tile and surrounding play.
Try this hand at the table.
Open the in-game Glossary, choose SBR and Win after Kong, then tap Try It for a practice match one move from Hu.
