OneShot is an indie puzzle adventure game developed by Future Cat, first released as a game jam entry in 2014 and launched on Steam in 2016. Players guide Niko, a small cat-like child, through a fading world by solving point-and-click puzzles, and each solved puzzle is rewarded with a cheerful confirmation jingle. Fans of the game have ripped that jingle for use in edits and streams, where it now works as a universal 'correct answer' sting, much like a classic ding sound effect, marking the moment a tricky problem finally clicks.
