槓上開花 · Gong Seung
Win on Kong (槓上開花 · Gong Seung) is a Hong Kong mahjong scoring bonus: You made a kong, drew the free replacement tile — and that tile completed your hand. 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 Win on Kong 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, Win on Kong 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.
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.When it happens: you win on the bonus tile drawn right after declaring a kong.
You kong the 5-dots, draw the free replacement tile, and it finishes the hand. The kong itself scores too — the two always arrive together.
Passed to Mahjiku's scoring engine on the Legacy additive reference sheet (self-drawn, fully concealed, seat wind South, round wind West), that hand comes back as:
| Line the engine emitted | Faan |
|---|---|
| Dragon Pung箭刻 | +1 |
| Base底 | +1 |
| Concealed Hand門前清 | +2 |
| Kong槓 | +1 |
| Win on Kong槓上開花 | +1 |
| Total | 6 |
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.
