Kong on Kong / Replacement Tile (杠上花)
Kong on Kong — winning on the replacement tile drawn after declaring a kong.
How Kong on Kong / Replacement Tile (杠上花) works
Kong on Kong, also called a replacement-tile win, occurs when a player wins on the bonus tile drawn immediately after declaring a kong.
After making any kong, the player takes a replacement tile from the wall, and if that tile completes the hand the win is credited as Kong on Kong. It rewards the lucky timing of the replacement draw and stacks with the underlying hand's other patterns. It is the kong-draw counterpart to winning on the very last tile of the wall.
- •The win must come specifically from the replacement tile drawn after a kong, not from a normal draw.
- •It can chain when a replacement draw allows another kong, leading to successive replacement wins.
- •Because it is a self-drawn replacement, it pairs with self-draw bonuses rather than discard-based ones.
Kong on Kong / Replacement Tile (杠上花) — FAQ
Does it matter whether the kong was concealed or exposed?
The bonus is about winning on the replacement tile; either an exposed or concealed kong can trigger the replacement draw that produces the win.
What if the replacement tile lets me declare yet another kong?
You draw again from the wall, and a win on that subsequent replacement tile still counts as a Kong on Kong win.
