The sound comes from The Sims, the life simulation game developed by Maxis and released in 2000 for PC. In the game, short musical cues give players immediate feedback on needs, actions and outcomes, and this success cue became one of the most recognisable. As Sims clips and gaming edits spread on YouTube and social media, the chime escaped the game and became shorthand for achievement online. Its clear, positive tone is understood even by viewers who never played, which is why creators still use it for wins and completed tasks.
