[Help Thread] About fanxin rounded cube

[taghi]

hi
I am a new rubik learner , I've bought a fanxin rounded cube (maybe a mistake for a noob?)

sometimes I manage to solve the cube using normal 3x3x3 methods, but sometimes I reach this unsolvable state:

In this state after I scramble the cube, I manage to solve it.
my cube is brand new and I've never disassembled or take apart the cube.
I cant understand why this happens? is It me? or the cube? please help me.

Your cube is functioning properly. What you are seeing is barrel cube parity (i think). Problems like this are what make 3x3 shape mods extremely fun but also aggravating at times. You can get cases that are not possible on a regular 3x3!

I believe this video will help you out.

ETA: Now that you know what you’re seeing is a possible case it can be fun to try and figure it out yourself/intuitively. That’s my favorite part about cubing, just racking my brain for hours trying out new puzzles.

You need to flip one of the 2nd layer edges, they will be still solved and it will be possible to make a cross.

Yes, as far as I know, you can flip the red red edge and it will be fine. Or maybe not, I don’t know much :fp

@Rafaello and @EngineeringBrian thanx guys. I've tried both methods (which I think essentially are the same) and it worked out.
thanx again.
