You won on the very last tile.
You win on the very last tile available from the wall. In Hong Kong scoring this covers both forms: drawing the wall’s final tile yourself, and winning on the final discard of the hand.
It is one faan. The pattern is about timing alone and ignores the shape of your hand.
You cannot aim for this, but you can position for it. As the wall runs down, a hand on a wide wait is far more likely to catch the last tile than one waiting on a single copy. Late in a hand, switching to a wider wait is often worth more than holding out for a bigger pattern.
Counting it whenever you win late. It is the last tile, not merely a late one. If even one draw remains after yours, the row does not apply.
It adds one faan to whatever else the hand scored, so it is pure bonus. With Self Draw it is two faan on top of your pattern. Because it fires so rarely, it often supplies the single faan that lifts a hand over a table’s minimum.
Does it count if I win on the last discard rather than the last draw?
Yes. Hong Kong scoring treats both endings as the last tile, for one faan.
Does it stack with Self Draw?
Yes. Drawing the wall’s final tile yourself scores both rows, for two faan.
What if the hand ends in a draw instead?
Then nobody scores. This row needs a winning hand on that final tile.
