Pure Double Chow

一般高 · Yat Bun Gou

Pure Double Chow (一般高 · Yat Bun Gou) is a Hong Kong mahjong hand: The same run twice over — the identical three tiles, same suit, appearing two times. The legacy additive reference sheet prices it at 5 faan, and every win also carries the 1 faan base, so a hand whose only named line is Pure Double Chow totals 6 faan. Under the legacy additive payout that 6 faan is the payment itself: the winner collects 18 points on a self-draw (自摸), when all three opponents pay 6 each, or 6 from the single player who discarded the winning tile (點炮). These are legacy additive reference values; tables choose their own sheet.

Unless another sheet is named, examples use the legacy additive reference sheet. Fresh installs select Half Spicy, whose hand values and payments differ. Check the sheet selected for your table.

Legacy additive reference value, from the patterns block of the legacy additive reference sheet. 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 Pure Double Chow at the table

Two matching ladders, exactly the same numbers and suit.

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 on the Legacy additive reference sheet (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. The table below keeps the legacy additive reference sheet's hand values and changes only its payout model. The half/full rows are illustrative payout overrides, not the Half Spicy or Full Spicy presets, which also change hand values and settlement.

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
辣辣上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.
