Pure Outside

純全帶幺 · Sun Chuen Daai Yiu

13faan

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 Outside means

Every set and the pair touches a 1 or a 9 — and there are no winds or dragons at all.

How to spot it. Every group reaches a 1 or 9, with zero honours.

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
Pure Outside純全帶幺	+13
Base底	+1
Total	14

What 14 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	14	+42	+14
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 14-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

Gives way to All Honours (20 faan) — when a hand qualifies for both, the engine emits only the bigger name. See All Honours.
Gives way to All Terminals (16 faan) — when a hand qualifies for both, the engine emits only the bigger name. See All Terminals.
Cannot appear with Mixed Outside — the engine reads a hand as exactly one of these; the two describe the same tiles in incompatible ways. See Mixed Outside.
