What’s the fastest game you won?

The fastest game I ever won was playing 15 seconds versus 5 minutes. In high school, we played 5-minute chess with progressive time odds. Each time you won, you received less time the next game. So it was 5 versus 4 minutes, then 3 minutes, etc. If you won at 5 vs 1, you had 30 seconds the next game. And then 15 seconds. I managed to win one with 15 seconds.

Did u win 10 sec?
when i was like 8 yo (in an over the board game obisouly), I delivered the scholar's mate. The funny part of the story, is that I just learned that mate the same day, after someone else checkmated me that way lol
