Geometry Dash is a rhythm platformer created by Swedish developer RobTop Games and first released in 2013. Secret coins have long been optional collectibles hidden in levels, rewarding exploration and precise play. The Tower arrived as a platformer-style mode in the major 2.2 update, giving this coin pickup a new context separate from the classic cube levels. Clips of the short chime spread through gameplay videos, level showcases and edits on social platforms, where its instant recognition as a reward cue keeps it popular with creators.
