Scattered Stars

全不靠 · Chuen Bat Kaau

Scattered Stars (全不靠 · Chuen Bat Kaau) is a Chinese Official (MCR) mahjong hand: No sets at all: five or six different winds and dragons, filled out with eight or nine tiles taken from the Split Straight pattern (1-4-7 · 2-5-8 · 3-6-9). Must be self-drawn. Mahjiku's default sheet prices it at 0 faan — it ships switched off, so a win whose only named line is this one is worth just the 1 faan base until a table gives it a value in House Rules. Payment follows the hand's whole faan total, not this line alone: under Mahjiku's default additive model the total is what each payer hands over — all three opponents on a self-draw (自摸), the discarder alone on a discard win (點炮). Faan values are a table's own call; this is Mahjiku's shipped default, editable in House Rules.

Chinese Official (MCR) pattern. Scattered Stars comes from the Chinese Official ruleset (MCR / 中國麻將競賽規則), not Hong Kong scoring. Mahjiku ships it as an optional House Rules pattern inside its Hong Kong engine — off by default. See the Chinese Official (MCR) patterns section of the library.

0faan

Worth nothing in Mahjiku's default rule set — it is shipped switched off, and a table turns it on by giving it a value in House Rules. Your table can price it differently; the engine reads whatever your rule set says.

How to spot Scattered Stars at the table

A hand of loose singles — honours plus scattered 1-4-7 / 2-5-8 / 3-6-9 tiles.

An example

What it adds up to

Priced at 0 in the shipped default, Scattered Stars adds nothing to a hand's total — a win that names only this one is worth the 1 faan base and no more. A table that wants it to count gives it a value in House Rules, and the engine starts adding it.

What 1 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	1	+3	+1
半辣上half spicy	0	+0	+0
辣辣上full spicy	0	+0	+0

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. Under a doubling table a hand below the 3 faan minimum pays nothing at all — the zeros above are the engine's minimum-faan gate, not a rounding artefact.

Try it yourself

Scattered Stars is a House-Rules option rather than a chip on the calculator, so it has no switch there. The engine does score it once your table gives it a value; the calculator totals up everything else in the hand.
