純全帶幺 · Sun Chuen Daai Yiu
Pure Outside (純全帶幺 · Sun Chuen Daai Yiu) is a Hong Kong mahjong hand: Every set and the pair touches a 1 or a 9 — and there are no winds or dragons at all. The legacy additive reference sheet prices it at 13 faan, and every win also carries the 1 faan base, so a hand whose only named line is Pure Outside totals 14 faan. Under the legacy additive payout that 14 faan is the payment itself: the winner collects 42 points on a self-draw (自摸), when all three opponents pay 14 each, or 14 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.Every group reaches a 1 or 9, with zero honours.
These are not illustrative numbers: the tiles above were passed to Mahjiku's scoring engine on the Legacy additive reference sheet (won on a discard, with sets claimed from the table, seat wind North, round wind North) and this is the breakdown it returned.
| Line the engine emitted | Faan |
|---|---|
| Pure Outside純全帶幺 | +13 |
| Base底 | +1 |
| Total | 14 |
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 | 14 | +42 | +14 |
| 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 14-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.
