Kong on Discard (杠上炮)
Kong on Discard — winning on a discard that came immediately after another player declared a kong.
How Kong on Discard (杠上炮) works
Winning off a discard that an opponent makes immediately after declaring a kong and taking the replacement draw.
Kong on Discard occurs when a player declares a kong, draws a replacement tile, and then discards a tile that completes another player's hand. The win is credited to the player who claims that post-kong discard. It is a timing pattern tied to the kong sequence and the discarded tile is, as always, a number-suit tile outside the winner's voided suit.
- •This pattern hinges on the discard happening right after a kong's replacement draw, not on an ordinary discard.
- •It rewards the claimant of the discard, distinct from the kong declarer's own draw-timing bonuses.
- •The claimed tile is a number-suit tile and cannot belong to the winner's voided suit.
Kong on Discard (杠上炮) — FAQ
Who scores Kong on Discard, the kong declarer or the winner?
The player who wins by claiming the discard scores it; the kong declarer is simply the one who discarded the completing tile.
How does this differ from a robbed-kong type win?
Here you win on the tile discarded after the kong's replacement draw, not on the kong tile itself being snatched away mid-declaration.
