Pure Double Chow

一般高 · Yat Bun Gou

5faan

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 Pure Double Chow means

The same run twice over — the identical three tiles, same suit, appearing two times.

How to spot it. Two matching ladders, exactly the same numbers and suit.

An example

defines it

filler

The bright sets are the ones that make it Pure Double Chow; the faded sets are ordinary filler that any hand needs.

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
Pure Double Chow一般高	+5
Base底	+1
Total	6

What 6 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	6	+18	+6
半辣上half spicy	32	+96	+32
全辣上full spicy	64	+192	+64

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.
