On December 16, 2015, RobTop announced a free expansion of G,D called Geometry Dash Meltdown, which was released on Decemfor iOS and Android. Since it is common for users to abuse and vandalize the online music portal to upload songs not made by them to use in Geometry Dash, RobTop implemented a manual approval system to prevent this, where he would choose what artists' works are allowed to be used in-game.It is unclear whether some of these artists would return in Update 2.2. In addition to the official songs, usage of most songs on the Newgrounds music portal is also available for User Levels. The Geometry Dash soundtrack is created several electronic music artists, including ForeverBound, DJVI, Waterflame, DJ-Nate, F-777, Dex Arson, and MDK. The difficulty setting is determined by Robert Topala the creator of a given level, its players, and moderators capable of sending levels can influence this decision. Changes after the verification will render it unverified. The player must complete their level with all coins in normal mode in order to ensure that it is possible to beat before it can be uploaded. The paid full version features the ability to upload and download user-created levels. A level cannot be officially completed on practice mode, though completion can lead to certain rewards. Geometry Dash has a practice mode that can be used for any level which allows the player to restart at manually or automatically placed checkpoints instead of the very beginning.

Players can also earn achievements which may be exchanged for rewards.Players may also utilize a shop, where they can spend an in-game currency called 'mana orbs', collected through completing levels.

Players can play the levels in almost any order. Levels are classified by difficulty, and each difficulty give a certain number of stars depending on difficulty. Each official level has 3 secret coins, which are used to unlock the three locked levels. Each level grants rewards upon completion. There are 3 levels in Meltdown and Subzero and 10nin World. There are 21 official levels in the full version of Geometry Dash, 18 of which are unlocked from the start.
