門前清 · Mun Chin Ching
bonus block of the shipped Hong Kong ruleset. Your table can price it differently; the engine reads whatever your rule set says.You built your whole hand yourself, never taking a tile from another player’s discard to complete a set.
How to spot it. No sets were claimed off the table — everything came from your own draws.
A plain four-runs-and-a-pair hand, built entirely from your own draws. Claim even one set off the table and the Concealed Hand line disappears — the rest of the hand scores the same.
Passed to Mahjiku's scoring engine (self-drawn, fully concealed, seat wind South, round wind West), that hand comes back as:
| Line the engine emitted | Faan |
|---|---|
| Ping Hu平和 | +2 |
| Base底 | +1 |
| Concealed Hand門前清 | +2 |
| Total | 5 |
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 | 5 | +15 | +5 |
| 半辣上half spicy | 24 | +72 | +24 |
| 全辣上full spicy | 32 | +96 | +32 |
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.
