All Green

綠一色 · Luk Yat Sik

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 All Green means

Every tile is green: the 2, 3, 4, 6 and 8 of bamboo, plus the green dragon (發). A famous showpiece hand.

How to spot it. Only green tiles — green bamboo and the green dragon.

An example

What the engine scores that hand at

These are not illustrative numbers: the tiles above were passed to Mahjiku's scoring engine (won on a discard, with sets claimed from the table, seat wind North, round wind North) and this is the breakdown it returned.

Line the engine emitted	Faan
All Green綠一色	+20
Dragon Pung箭刻	+1
Base底	+1
Total	22

The 20 faan for All Green is only part of it. The same tiles also satisfy Dragon Pung (+1) — patterns stack in Hong Kong scoring, which is why a hand named for one shape often pays a good deal more than that shape's own value.

What 22 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	22	+66	+22
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 22-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 Half Flush (6 faan) — the Half Flush branch is guarded by `&& !allGreen` — All Green replaces the Half Flush its tiles would otherwise read as. Net effect: the 20 faan for All Green lands instead of 6, a difference of +14. See Half Flush.
Cannot appear with All Honours — the engine reads a hand as exactly one of these; the two describe the same tiles in incompatible ways. See All Honours.
Cannot appear with Nine Gates — the engine reads a hand as exactly one of these; the two describe the same tiles in incompatible ways. See Nine Gates.
Cannot appear with Full Flush — the engine reads a hand as exactly one of these; the two describe the same tiles in incompatible ways. See Full Flush.
