GeoGuessr is a browser-based geography game in which players are dropped into a Street View location and must pinpoint where they are on a world map before the round timer ends. The countdown sound comes from that in-game timer, and it became familiar outside the game as streamers and YouTubers shared close finishes, wrong guesses and last-second wins. Short clips of those moments spread on TikTok and YouTube, where the sound alone now signals a timed guessing challenge even without gameplay footage.
