Geometry Dash is a series of five video games (Geometry Dash, Geometry Dash Lite, Geometry Dash Meltdown, Geometry Dash World and Geometry Dash SubZero) developed and published by Sweden-based indie video game developer Robert Topala, and his own company RobTopGames.

The games are 2D platformers where the player is moving in the level itself continuously by the X+ axis and the player must jump, fly, flap, swing and change gravity within the music's beat through various gamemodes and complete the level without clashing an obstacle. The main game Geometry Dash, as of update 2.113, has a total of 21 official levels and has nearly 60 million user created levels.

According to RobTop, the infamous 2D platformer The Impossible Game took part in giving him inspiration for making this game.
