Is there an impossible situation on the latch cube, where nothing will rotate?

If nothing can rotate, how would it rotate into that position?

Because the latch cube has arrows that show internal bandaging.

Certain faces can be rotated one direction only, because of the arrows on the faces.

(obviously not because of the stickers, but the stickers show where it is on the internals.

Whoops, my bad, I just figured it out

Speaking of which, new puzzle idea. Take a latch cube, then resticker it! That way, nobody will know which turns are restricted!

Well, by disassembling and reassembling, you can do it. The super-flip position is such a position.

Did anyone solve it already?
(after messing it reasonably, of course)

I find it really difficult. Almost impossible if you ask me.
But I never looked for any solving information or advice (yet).

Bhearn had solved it within about 48 hours of getting it.

Well done... but you didn't have IPP to distract you!

from my perspective, and that of my camera, neither did you

Although, in fairness I remember you explaining a few moves to me so maybe that would count.

I solved it before I get it.
I used the simulator.

Wow!
I suppose that all of you who have solved it did not use any algs that we know right? I imagine that the majority of the known algs would simply not be possible. Am I wrong?

Congrats!

I have solved the first layer (edges + corners with correct placement and orientation) but now I'm completely stuck. Only 2 faces of the cube can be rotated.

I suppose that this is not a good approach (F2L).

It seems to me that the heise method may be the most useful here, no?

You can use CFOP to solve the Latch cube.
