大四喜 · Dai Sei Hei
patterns block of the shipped Hong Kong ruleset. Your table can price it differently; the engine reads whatever your rule set says.A triplet of all four winds — East, South, West and North. Among the rarest hands there is.
How to spot it. Four wind triplets — every wind.
The bright sets are the ones that make it Big Four Winds; the faded sets are ordinary filler that any hand needs.
These are not illustrative numbers: the tiles above were passed to Mahjiku's scoring engine (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 |
|---|---|
| Half Flush混一色 | +6 |
| Big Four Winds大四喜 | +18 |
| All Triplets對對糊 | +6 |
| Base底 | +1 |
| Total | 31 |
The 18 faan for Big Four Winds is only part of it. The same tiles also satisfy Half Flush (+6), All Triplets (+6) — patterns stack in Hong Kong scoring, which is why a hand named for one shape often pays a good deal more than that shape's own value.
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. Both are shipped in Mahjiku; the additive model is the default.
| Payout model | One payer owes | Self-draw 自摸 | Discard 點炮 |
|---|---|---|---|
| Additivefaan is the payout | 31 | +93 | +31 |
| 半辣上half spicy | 384 | +1152 | +384 |
| 全辣上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 31-faan hand is paid at the 13-faan row — 384 points under 半辣上 and 8192 under 全辣上. Everything above 13 faan pays the same. The additive model has no ceiling, so there the extra faan still count.
