Geometry Dash is a series of music platform video games developed by Swedish developer Robert Topala, better known as RobTop. The first game, simply called Geometry Dash, was released on August 13, 2013, on iOS and Android, and the Steam version was released on December 22, 2014. In Geometry Dash, players Control the movement of an icon (square, airship, ball, UFO, arrow, robot, spider, swing) and music-based navigation to get it to the finish line, while avoiding obstacles. Obstacles like spikes, cogs, and shield walls can instantly destroy icons upon impact.

Geometry Dash currently includes 26 official stages. It is famous for its extensive level creation system, where players can create their own custom levels, share them online, and play levels designed by other players. More than 95 million levels with many different levels have been created. In addition to the official levels, certain user-created levels have been featured in the main game content, such as the Map Pack, Gauntlet, List, Daily Level, Weekly Demon, and search bar. In-game currency, such as stars, secret coins, user coins (verified only), energy orbs, or diamonds can be obtained from chests or official levels (where you can only get secret coins) and user-created levels (in which users can only get coins).

Depending on the platform on which the game is played, Geometry Dash can be played using a touchscreen, keyboard, mouse, or controller. Players control the movement of their icon through input in the form of pressing or holding, with the goal of completing a level by reaching its end. Notably, if the icon is destroyed, the level will start from the beginning, the exception is in practice mode, where landmarks are marked with green diamonds along the direction of travel. icon moves (the icon after death will return to the nearest landmark), and players can survey the structure (layout) of the level and practice the level before officially completing that level. The timing and rhythm of the game's music are important parts of the game, often related to each other.

In the game, the player's symbol takes the form of one of eight different shapes. Each icon has a different movement pattern with each control. Symbol movement is further complicated by portals, which allow players to change between symbols, reverse the direction of gravity, change the size of their symbols, mirror their movement direction, change the speed degree of symbol or teleportation. Furthermore, jump pads and rings can be used to move symbols in certain directions or change gravity.
