Geometry Dash is a fast-paced rhythm-based platformer game developed by Robert Topala and published by RobTop Games. Originally released in 2013, the game has become hugely popular for its challenging gameplay, catchy electronic music, and minimalistic geometric visuals.

Players control a square-shaped character and must navigate through obstacle-filled levels by jumping, flying, or flipping gravity—always in sync with the background music. Timing and precision are key, and even a single mistake means starting over from the beginning of the level.

There are several versions of the game:

- Geometry Dash (the full version with multiple levels and a level editor)
- Geometry Dash Lite (a free version with limited levels)
- Geometry Dash Meltdown, World, and SubZero (spin-offs with unique levels and soundtracks)

One of the most loved features is the community level editor, which allows players to create and share custom levels. This has led to a huge and active fan community, with thousands of user-generated levels to explore—many of which are incredibly creative and challenging.

Geometry Dash stands out for being easy to pick up but extremely hard to master, making it a favorite for gamers who enjoy a real test of reflexes and rhythm.
