Geometry Dash is a rhythm-based platform game released in 2013 by Swedish developer RobTop Games. Most official levels hide three secret coins, usually yellow and placed on risky alternate routes, and collecting them unlocks new icons and achievements. The short pickup chime became familiar through years of level playthroughs, fan-made levels and completion videos on YouTube and TikTok. Because players associate the sound with finding something hidden, creators now reuse it outside the game whenever a video needs a clear, instant reward signal.
