Sandbox
Literally impossible to lose unless you press the quit button or fail it deliberately. It is always 100% pass unless you don't play it seriously, as in leaving the character to just run automatically, or to try and die on purpose.
These levels are extremely rare. Only two levels are in this category.
It is very difficult to fall out of the tunnel, especially since the holes are only a tile wide.
2
Very easy
These levels are considered to be very easy. Most of the beginners can finish it in one take. Only careless or playing not seriously will lead to failure.
These levels are common in the first batch of levels, but are less common later. They are for tutorials and beginners.
The classic "Hard" level in the game. Small platforms, large gaps make this level famous. Fortunately, there are many tutorial videos in the Internet for this level.
11
Extra hard
These levels are really challenging, and sometimes it requires luck to finish.
This level is really challenging, and you need incredible memory to remember the locations of the platforms.The most difficult thing about the level is that when the power tiles blink, you don't know where you are, and you may be already reaching the edge of the platform you are standing on.
13
Hell
These levels (may contain minigames) are so hard that you think you may not be able to finish it. It requires maximum skills to finish.
Extremely rare. There are only 3 levels in this category, which are Plan A, part 16 anything Level U-8/Bridge, and Level I-5. Mostly, this type of difficulty is given to the winners of this poll.
This level is extremely hard, one of the hardest, longest and most notorious levels in Run 3. In this level you have to jump through different small platforms, most of them only one-tile large, making jumps incredibly hard. There are even boxes, which can hinder your jump. We wish you good luck with beating this level, and congratulate you if you beat arguably (one of) the hardest level(s) in the whole of Run 3.
Trivia
There is once a difficulty called "Almost impossible", but it is now scrapped. The reason is that there are not enough Hard levels, so there will not be enough levels in Almost impossible difficulty. All levels in the difficulty are now moved to Insanely hard difficulty.
