[puzzle] What's wrong with these cubes?

[yejun]

No cube can be sovled. What's wrong?

What even is this?

 

[yejun]

There is something wrong in these six cubes. Can you find out them?

I'm assuming this is a logic puzzle where you have to figure out how these stickerings are impossible. Here's what I think.

Spoiler

1: Two blue-yellow edges
2: Five yellow edge stickers
3: Blue is adjacent to all colors (see UFR corner and UR edge)
4: UFR corner is mirrored
5: UFL and RUB corners are the same
6: From the UFR corner we know yellow is opposite white and green is opposite blue. That means the UFR corner is red-yellow-green, the UFL corner is red-blue-yellow, the URB corner is red-green-white, and the DFR corner is red-white-blue. So that's four red corners. But we see a fifth red corner at RDB.

1) Two blue/yellow edges
2) 5 yellow edges
3) blue/green edge means L or B face has to be green so blue yellow purple corner can't exist
4) blue and red stickers on white blue red corner in the wrong places
5) two corners with white-purple going clockwise
6) corners at ULF and DRB both have to go to UBR

These were fun, thank you. Last one took me much longer than it should have.

Great logic puzzles

On the other hand, if you give this to someone who doesn't know much about the cube, they will say it's bogus.
