Ice Carbon Diablo X (commonly abbreviated to ICDX) is a 1.6 Extreme Demon created and hacked by Roadbose. Riot was the very first person to complete it legitimately. It now sits at #65 on the Official Extreme and Insane Demons Ranking List.


This level is hands-down an Extreme Demon, and used to be one of the hardest levels in Geometry Dash, the other being Cataclysm, until it was discovered that Roadbose actually hacked the level. Which of these levels is harder has been a matter of debate among Geometry Dash players for a long time. However, with the creation of Bloodbath, The Hell Factory, A Bizarre Phantasm, Yatagarasu, Sonic Wave, and Phobos, many arguments upon this subject have been discontinued. Nowadays it is considered as one of the easiest extreme demons.


The level starts off with a moderately difficult cube segment, consisting of an awkward jump over a sawblade. It then continues with a very hard ship sequence, going through very tight spaces and tight diagonals. It then goes into a very short ball, which has a blue orb over a spike. It is deceptively hard because it requires good timing to do it. Then, the player enters a UFO part, which has a very hard first obstacle requiring perfect timing, then goes into anti gravity, then a size portal. It then goes through a one block space through a cube portal, while still in mini mode. The cube is relatively simple involving a few fakes and simple jumps. In a part in the cube, there is a ship portal; however, it is just a trick to get you to fail. After passing the UFO portal, the cube segment becomes significantly harder with more skill being needed. It then goes into a very brief UFO segment, then avoiding the ship portal, going through the "Demon-heads" into another cube section. After that, the ship part that follows is extremely hard, consisting of one-block spaces and invisible spikes. A slightly hard mini-cube then follows, which passes through a simple UFO segment, then returns to a cube segment, which then becomes an anti-gravity ship sequence with a tight diagonal space, which then reverts into a cube segment with a few obstacles. A very hard ball part comes after, involving timed switches, fakes, and orb jumps. It then enters an easy mini UFO segment which is nearly identical to Clubstep's first UFO segment, then passes through an easy ship sequence into a hard cube segment, involving a lot of timing and numerous fakes. It then transitions to a very hard ball segment, which required even more timing and memorization compared to the one before it. After that is a very hard ship, which is almost purely made of one block spaces, then into a cube with many fakes. A ship similar to the second one follows, which then becomes mini and goes into a semi-tight diagonal part, then goes back to being a cube, and then a very short one-switch ball comes and instantly reverts to cube, which then enter the last part of the level, at 95%, a mini-ship sequence that goes to one block spaces with gravity portals, then the player arrives at the creator's name, then to another, and the last one block space. Then, the level ends.


  • This level was once thought to be impossible until 1.9, when Riot beat it.
  • Andromeda originally hacked the level, but later had re-beaten it legitimately.
  • This level had originally had more dislikes than likes. However, when Cyclic completed it, it got a huge number of likes.
  • On March 1, 2017, this level was accidentally hacked by cos8o (proof:, when it and all of Roadbose's levels but not GW RoadMC2's were all somehow moved to Powerbomb's account.
