First heard in Nintendo's Super Mario Bros. in 1985, the coin sound has followed Mario through decades of sequels, spin-offs and remakes, becoming one of the most recognisable sounds in gaming. Its simple electronic chime was designed to reward collecting coins, and that association stuck as the games spread worldwide. Today creators reuse it far beyond gameplay, in memes, reaction clips and short-form videos, because a single short ping instantly reads as success, money or a level-up to viewers of all ages.
