The game beeps if you get a guess incorrect.

Yes but for at least some of us, the confetti was seen on the round where we used our last guess. So we are wondering how the commenter knows there weren't more rounds. Did you get confetti on a round that you know to have guessed correctly?

Edit: I just played again and am confident that my guess before the confetti was correct.

I definitely guessed the last one correctly, because it was obvious to me, as were nearly all of them.

I'd have to go back through it and deliberately fail on the last one to confirm, but I assumed I'd get the error beep on the past one if it was wrong.
