Players control a square-shaped avatar through a series of challenging stages in geometry dash that are chock-full of obstacles, jumps, and traps. Because the music and gameplay are so closely synchronized, players must match their movements to the background music. The rhythm and platforming elements of the game make it both difficult and addicting. With the help of the level editor in the game, players may make and share their own levels, boosting replay value and community involvement. To maintain interest, there are numerous game modes and settings.

The game has a reputation for being both extremely difficult and rewarding, especially for those who wish to finish user-generated levels and achieve high scores. Its simplistic graphics contrast with the intricacy of its levels.
