Double Kong Win

雙槓 · Seung Gong

Double Kong Win (雙槓 · Seung Gong) is a Hong Kong mahjong scoring bonus: Lucky on lucky: your kong’s replacement tile made a second kong, and that kong’s replacement won. Very rare. Mahjiku's default sheet prices it at 3 faan, and every win also carries the 1 faan base, so a hand whose only named line is Double Kong Win totals 4 faan. Under Mahjiku's default additive payout that 4 faan is the payment itself: the winner collects 12 points on a self-draw (自摸), when all three opponents pay 4 each, or 4 from the single player who discarded the winning tile (點炮). Faan values are a table's own call; this is Mahjiku's shipped default, editable in House Rules.

3faan

Mahjiku's default value, from the bonus block of Mahjiku's default rule set. House rules vary from table to table — this is one common setting, not the only "correct" one. Your table can price it differently; the engine reads whatever your rule set says.

How to spot Double Kong Win at the table

When it happens: two kong-replacement draws in a row, winning on the second.

What it adds up to

Every win starts at 1 faan for the base, so a hand whose only named line is Double Kong Win is worth 1 + 3 = 4 faan. Anything else the hand happens to be — a flush, a triplet shape, a dragon set — stacks on top of that.

What 4 faan actually pays

Faan is not the score by itself — it is the number the table turns into points, and Hong Kong tables do that two different ways. Both are shipped in Mahjiku; the additive model is the default.

Payout model	One payer owes	Self-draw 自摸	Discard 點炮
Additivefaan is the payout	4	+12	+4
半辣上half spicy	16	+48	+16
辣辣上full spicy	16	+48	+16

Self-draw: all three opponents pay. Discard: only the player who threw the tile pays. Both columns are the winner's gain, straight out of the app's settlement function.
