Coin-collecting sounds have been a shorthand for reward in arcade and platform games since early video games, where a short chime told players instantly that they had gained points, health or an extra life. That simple feedback loop made the sound easy to recognise even outside games, and editors later borrowed it for streams, reaction clips and short-form videos. It remains popular because it needs no explanation: a bright ding immediately signals success, progress or a small, satisfying payoff for the viewer.
