四槓 · Sei Gong
Four Kongs (四槓 · Sei Gong) is a Hong Kong mahjong hand: Four kongs in one hand — four separate sets of four. Almost never seen. The legacy additive reference sheet prices it at 20 faan, and every win also carries the 1 faan base, so a hand whose only named line is Four Kongs totals 21 faan. Under the legacy additive payout that 21 faan is the payment itself: the winner collects 63 points on a self-draw (自摸), when all three opponents pay 21 each, or 21 from the single player who discarded the winning tile (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.
patterns 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.Four declared kongs.
The bright sets are the ones that make it Four Kongs; the faded sets are ordinary filler that any hand needs.
Four declared kongs — eighteen tiles, because each kong puts a fourth aside. The catalog picture above shows the shape; this is what the engine pays for it.
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 |
|---|---|
| Four Kongs十八羅漢 | +20 |
| Base底 | +1 |
| Concealed Hand門前清 | +2 |
| Kong槓 | +4 |
| Total | 27 |
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 | 27 | +81 | +27 |
| 半辣上half spicy | 384 | +1152 | +384 |
| 辣辣上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 27-faan hand is paid at the 13-faan row — 384 points under 半辣上 and 8192 under 辣辣上. Everything above 13 faan pays the same. The additive model has no ceiling, so there the extra faan still count.
