Four Kongs

四槓 · Sei Gong

20faan

Mahjiku's default value, from the patterns block of the shipped Hong Kong ruleset. Your table can price it differently; the engine reads whatever your rule set says.

What Four Kongs means

Four kongs in one hand — four separate sets of four. Almost never seen.

How to spot it. Four declared kongs.

An example

defines it

filler

The bright sets are the ones that make it Four Kongs; the faded sets are ordinary filler that any hand needs.

A worked hand

Four declared kongs — eighteen tiles, because each kong puts a fourth aside. The catalog picture above shows the shape; this is what the engine pays for it.

Passed to Mahjiku's scoring engine (self-drawn, fully concealed, seat wind South, round wind West), that hand comes back as:

Line the engine emitted	Faan
Four Kongs十八羅漢	+20
Base底	+1
Concealed Hand門前清	+2
Kong槓	+4
Total	27

What 27 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	27	+81	+27
半辣上half spicy	384	+1152	+384
全辣上full spicy	8192	+24576	+8192

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.

Worth knowing. Both doubling tables stop at 13 faan, so this 27-faan hand is paid at the 13-faan row — 384 points under 半辣上 and 8192 under 全辣上. Everything above 13 faan pays the same. The additive model has no ceiling, so there the extra faan still count.

How it interacts with other hands

Replaces Four Concealed Pungs (18 faan) — the set-type ladder is `if (kongs === 4) … else if (pungs.length === 4)`. Net effect: the 20 faan for Four Kongs lands instead of 18, a difference of +2. See Four Concealed Pungs.
Replaces All Triplets (6 faan) — the set-type ladder is `if (kongs === 4) … else if (pungs.length === 4)`. Net effect: the 20 faan for Four Kongs lands instead of 6, a difference of +14. See All Triplets.
Cannot appear with Ping Hu — the engine reads a hand as exactly one of these; the two describe the same tiles in incompatible ways. See Ping Hu.
Cannot appear with Seven Pairs — the engine reads a hand as exactly one of these; the two describe the same tiles in incompatible ways. See Seven Pairs.
