The original jingle comes from Pac-Man, Namco's maze-chase arcade game released in Japan and the United States in 1980. Its short electronic intro, played when a new game starts, became one of the most recognisable sounds in gaming. Reversed versions like this one are fan-made edits shared on soundboards, meme pages and video editors as a novelty twist on the familiar tune. Creators keep using it because the backwards melody is instantly identifiable yet disorienting, making it a handy audio cue for rewinds, glitches and jokes about things going wrong.
