Geometry Dash Sakupen Hell is an Extreme Demon 1.9/2.0 level created by Noobas. It is considered one of the most difficult levels to complete, surpassing Bloodbath.
0–16%: The level begins with a moderately difficult cube section. Players do not need to hit all three green orbs at the start. They can only hit the first orb if they time the delay. The speed then triples, and players must navigate a brief, tricky wave segment that lasts around a second.
16–29%: Players continue with a difficult wave section in an extremely tight space.
29–40%: The speed slows down, and players encounter a simple, small cube section with a few fake spikes. The speed then triples again, and players face the most difficult wave segment.
40–74%: Players enter a tight UFO section with numerous gravity portals. This leads to a normal-sized ship segment that transitions into a smaller ship.
74–89%: This is the easiest part of the level. Players can simply spam the controls to get through.
89–100%: This section is characterized by a series of inverse mini-ship segments. Finally, the creator's and verifier's names appear, completing the level.
