About this sound
This is a sub-second electronic chime, the 1-Up cue from Super Mario Bros. that plays when Mario gains an extra life. It feels rewarding and nostalgic, like a tiny win delivered instantly. Its origin in Nintendo's 8-bit platformer era is why gamers recognise the reward signal immediately, even decades after first hearing it in play.
