The Challenge is a secret level playable in Geometry Dash World and Geometry Dash. It is the first level not to follow a chronological order among the official levels and features a number of Update 2.1 mechanics and objects, including the spider and dash orbs before said update was officially released.
The Challenge is a very simplistic level, having no aesthetic color changes in the entire level and almost no decorations. The level first introduces the player to the dash orbs, then later showcases the spider gamemode. A smiley will appear at the end of the level.
To unlock this level, the player must go to the Vault of Secrets (50 diamonds). The player must type in "The Challenge", and then collect 200 diamonds to unlock this level. Once completed, the player gains access to the Basement which also contains a chest with a new icon.
- The song used in the level is Random Song 06 by RobTop (formerly Zhenmuron) on Newgrounds. In the game files, however, it is called DJRubRub. This makes the song available from both Newgrounds and by hacking Geometry Dash's code to let the player use the song without having to download it from Newgrounds.
- This also makes the level name different from the song name.
- This level has the most bugs found out of all the levels, second being Deadlocked (all versions). A compilation of these bugs can be found here.
- This is the shortest official level, being the only one in Geometry Dash to be of medium length.
- Although the level officially doesn't give any kind of Icon, you can get a icon from the Basement that unlocks after you beat the level.
- The Challenge takes 27 seconds to complete and requires a minimum of 21 jumps, if you hold the green dash arrow, both in the normal and spider mode.
- Upon tapping the play button twice or more in succession, the game may glitch removing the player's ability to jump. If the player exits The Challenge, the game will crash,
- Upon leaving the level, the normal Geometry Dash menu music will play instead of the Vault of Secrets music.
