With a year under its belt, Tartarus has established itself as the most challenging stage to date. Only 8 people have finished the level so far. These are the best Geometry Dash players. Deadlocked is the most difficult main level in Geometry Dash. Deadlocked is like beating a level without spikes when compared to Tartarus, and that's an understatement. Players who have beaten Tartarus have had a tough time completing it, demonstrating that Geometry Dash is a challenging game for everyone. When you first start playing, it might be extremely challenging, but with time and practice, you will improve. I've only been playing for approximately 9 months and have already conquered 10 "Demon" rated levels (demons are the game's most challenging levels). The game appears to be easier as you practice more. Note: It took me over 4000 times to conquer certain levels, but with hard persistence, I was able to accomplish them. More than half a million attempts later, some individuals have still managed to succeed.
