Place this clip as the final reaction after the reveal in your edit, then follow a bigger win with the kids cheering sound to lift the ending, or precede a flop with the wrong answer game show sound for contrast.
O tym dźwięku
A short voice clip of someone enthusiastically shouting 'Bom demais!' in Portuguese, the phrase for something that is just too good. It runs about three seconds and lands as pure delighted approval, the kind of happy, satisfied reaction you use when food, luck or a result turns out even better than expected.
