1) Build up from a 3x3 Bandaged Cube, so it looks like a 2x2 on the outside. Some of the moves would be blocked. It would be a pain to get it scrambled and near impossible to solve it.

2) It looks like a regular cube out the outside. The trick is that you are restricted to using only the L, R, F and B faces. This is achieved by bandaging or gluing the U and D centers to the core, so they cannot move, so you cannot use those slices. You could add a clever stickering of some sort to indicate it is not a normal 3x3.

Huh?
I don't understand...

I understand exactly what you are saying. I am not the person to do that though. I don't have the money right now. I would love to own one though. That sounds like an interesting puzzle. It wouldn't be solved on the inside if you solved the 2x2 part of it right?

Since it is a bandaged cube, the insides would have to be correct for the corners (the visible 2x2) to be solved.

And to have this be a more reasonablely sized puzzle, you could bandage a Keychain Cube and build up from it.

it would be difficult to block the UD layers in a way that preserved the exterior appearance but remains strong enough to not break if someone who doesnt know what it is picks it up

Take your 3x3 apart.

Imagine maybe throwing a washer or two between the core and the center to maintain the normal distance the center piece is off the core. Then you would apply superglue to the base of the center to lock it to the core. Repeat for the opposite center.

Are you talking about the Fused Cube:

No.

A Bandaged cube ?
Or a Bandaged/Fused?

A Bandaged Cube. Not a fused cube. Due to the bandaging, slice moves are impossible, so not bandaging that 2x2x2 corner would increased the challenge.

Yeah I had built one and I never solve it...

The idea of gluing a face to the center was already mentioned (by me *proud*) in this topic:

The cube you described is equivalent to $C000000


I personally dislike puzzles, were something is hidden but this sounds really interesting...
Am I right, that you want to build up the 8 corners of the bandaged cube into the 8 corners of the 2x2x2? You don't want to make use of the edges glued to the faces?

Andreas, that is a fantastic thread! I can't believe I missed it before. It was so full of information. I found it very interesting. Congrats on coming up with such a novel idea (As well as 7,000 others)

And you analysis of the second puzzle is correct. Only the corners would be shown. The way the bandaged cube is made, you can only turn at most 3 of the 6 faces because the turn must include the free floating corner. So it would be impossible for the 3x3 core to be 'misaligned' because you can't use slice moves. So all of the edges glued to centers would still exist, but they would not be visible to the puzzler.

I think this challenge would prove next to impossible. I would classify it under the same difficulty as Bram's Unscrambled puzzle.

Thank you very much. Maybe it is time for an update of that GUI...
My other question: What is Bram's Uncrambled puzzle?

It's quite the puzzle.

I can't see any of the pictures on those threads
