How you win

Base

底 · Dai

Base (底 · Dai) is a Hong Kong mahjong scoring bonus: Every winning hand starts with one point, just for winning. It is always there — nothing to do. It is worth 1 faan in the legacy additive reference sheet and it is the whole of a win that names nothing else, which is why a table minimum of 3 faan really asks for 2 faan of actual pattern on top. Payment follows the hand's whole faan total, not this line alone: under the legacy 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). 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.

How to spot Base at the table

Counts automatically on any win.

What it adds up to

The base is 1 faan, and it is the whole of a win that names nothing else — which is why the table minimum matters: 3 faan is the floor, so a hand needs 2 faan of actual pattern on top of the base before it is a win at all.

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. 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.

辣辣上full spicy0+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.

The base is the one faan every win opens with, before a single pattern is named. It is why the smallest possible winning total is not zero, and why a table minimum of 3 faan really means "two faan of actual hand".

Try it yourself

There is nothing to tick for the base — every win the calculator scores already opens with it. Add the rest of the hand and watch the total move.
