Mario Kart Tour is Nintendo's mobile entry in the Mario Kart series, released in 2019 for iOS and Android, with races built around short tracks and a points system. Combos are central to that system, as drifting, jumping, hitting rivals, collecting coins and using items in quick succession extend a combo and raise the score. The short chime that accompanies a combo has become familiar to players through repeated races and tours, and creators now reuse it outside the game to signal a run of good moves, a lucky sequence or a rising score in edits and reaction clips.
