Main Levels, or the RobTop Levels, are the Levels that were coded into the game by the creator of the game, RobTop. They're meant to entice Players into the game and trinkle in all the features, one by one. These are seen in the Spin-Off Games and actual Geometry Dash. There are 21 different Main Levels in total in actual Geometry Dash, but there's also 16 other Main Levels from the Spin-Off Games.
The Main Levels in Geometry Dash count up to 23 different Levels as of Version 2.2. All Main Levels from Geometry Dash are roughly a minute and 30 seconds long in length, have a simple yet slick style and are only meant to get people to play the Community Levels, which are explained later. All Levels also have three Main Coins for the player to collect. These are often very well-hidden or hard to get.
