Yu-Gi-Oh began as a manga by Kazutaka Takahashi in 1996 and grew into anime series and a trading card game built around monster duels. In the anime, each duelist starts with a set number of Life Points, and on-screen counters update whenever a monster is destroyed or an effect deals damage. That ticking counter became one of the show's most recognisable duel sounds. Fans later lifted it for edits and soundboards, where it now signals any dramatic loss of health, points, or progress.
