Every Top 1 Demon in Geometry Dash

In an attempt to fit as many levels on this list, I go occasionally switch off from using the verification date, as well as the date when the level was placed on the demon list. Please note that although many levels were revealed to not actually be the hardest demon at the time after their #1 placement, I've still included them due to the community thinking otherwise at the time. I've also included one level that, while never placed at the #1 spot, was revealed to be harder than the current top demon later on.
