Last-Tile Discard

河底撈魚 · Ho Dai Lou Yu

Last-Tile Discard (河底撈魚 · Ho Dai Lou Yu) is a Hong Kong mahjong scoring bonus: You won on the very last discard of the hand, after the wall was empty — “catching a fish from the riverbed.” The legacy additive reference sheet prices it at 1 faan, and every win also carries the 1 faan base, so a hand whose only named line is Last-Tile Discard totals 2 faan. 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), and since 2 faan is under the 3 faan minimum, Last-Tile Discard is a top-up rather than a hand of its own. 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 bonus 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 Last-Tile Discard at the table

When it happens: the last tile anyone throws completes your hand.

A qualifying example and a counterexample

Example. West takes the last playable wall tile, cannot win, and discards the tile that completes South’s hand shown here. South claims it: Last-Tile Discard on the legacy additive reference sheet.

Counterexample. If South draws the winning tile directly from the end of the wall, that is Last-Tile Draw. A discard of a tile’s fourth copy earlier in the hand does not qualify as Last-Tile Discard.

What it adds up to

Every win starts at 1 faan for the base, so a hand whose only named line is Last-Tile Discard is worth 1 + 1 = 2 faan. Anything else the hand happens to be — a flush, a triplet shape, a dragon set — stacks on top of that.

That is under the table minimum of 3 faan, so Last-Tile Discard on its own never wins a hand. It is a top-up, not a hand.

What 2 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	2	+6	+2
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.
