Players of Geometry Dash control a little cube—or any customisable character—that goes forward on its own initiative. To reach the conclusion of a level, one must negotiate a sequence of challenges including jumps and dodging of spikes, gaps, and other hazards. The game is special in that it seems like an interactive music video by combining classic platformer features with rhythm-based gameplay: the obstacles and movement match to the beat of the music.

The challenge rises greatly as the player advances; later levels include more intricate challenges and faster tempos. Although the game is renowned for its extreme difficulty, for those who can finish demanding levels it provides a sense of achievement.

Geometry Dash boasts several levels, each having unique themes, images, and music tracks. Every level presents unique sets of challenges and barriers; players must finish one to access the next. While some levels introduce challenging sections where players must memorize the layout, others demand perfect timing for jumping and avoidance of hazards.
