Can't solve the last corner of my mirror blocks

[livingsoulsdie]

I cannot for the life of me figure out how to flip this corner piece.

If it is only one piece then it's unsolvable

Having just one corner (or edge) flipped is an impossible cube state, no moves will fix it. You'll to take the puzzle apart to fix it.

maybe another cube-shaped corner is also twisted. check all the other corners. it's difficult to tell on that puzzle.

 

[blakedacuber]

Its twisted. Also try starting with the smakk layer aparently it makes it easier

 

[livingsoulsdie]

I do not understand how it is impossible to solve. I just got it in the mail Brand new and it was in perfect solved position when I started. Wierd I think im going to just twist it up again and try to resolve it & see what happens. Thanks

There are a few 'laws of the cube' related to the kinda symmetry around it's movement. for example if not doing anything else you can swap a minimum of 3 edge pieces or 3 corner pieces (you can't swap two), but if you're swapping edge AND corner pieces you can do two of each. You can flip two edge pieces (not one or 3), and in your case if rotating corners if you do one corner clockwise then another corner must be twisted in an opposite direction.
What must have happened is that during the solve one of the corners just got turned around. This may seem really difficult to do normally, but mid turn there is more space for it to move about (though it's still pretty rare).

I think it's unlikely that one of the corners could get twisted while solving without it falling apart. That can happen on speed cubes that have tensioning springs but the mirror blocks is a rubik's brand. It doesn't have springs and doesn't cut corners. Most likely one of the corners that is almost square is also mis-oriented.

Either a near-cubic corner is also twisted or (and I don't have a mirror block, but this happens on some of my other shape shifting 3x3s) there is a corner that is a cube and is also twisted. This can happen on cubes like the pyramorphix cubes and others like that, where some corners are perfectly symmetrical and can be rotated and still be flat with everything else.

Interesting points, but I have three criticisms. 1) how do we know it's a Rubik's brand. 2) There aren't any corners that are quite square like. the biggest corner is the closest to a sqaure but even so it should be incredibly obvious if it wasn't in correctly. 3) Due to the weird sticky-outy-ness (that's a technical term) it's probably even easier to catch a corner and have it flip around during a solve than a normal 3x3 and we know that that can still happen.

Edit: ok I just flipped my 'most square' corner. No, it's essentially impossible that it could be flipped without anyone noticing it.

Sorry, I thought Mirror Block cubes were all Rubiks. I understand your points. However, is it possible to solve it to produce a cuboid where all the edges line up but is not exactly cubic. Perhaps it is possible apart from one corner being rotated. I don't have one so I can't check and can't work it out in my head.
Edit: Thinking about it, that can't be possible since the centres can't move and so fix it to a cubic shape.

Na, every piece has different sizes x/y/z dimensions, if anything is twisted it just sticks out as obviously as the piece in the picture.
I'd recommend mirror cubes btw, I got this one which is super cheap yet turns really well (even cuts corners nicely). It's pretty fun.

You are absolutely right & have helped me to figure out what was going on. I turned the top so the edge was hanging over & the corner practically flipped it self around.
Thank you. I knew it had to be something stupid. Im a big cube guy and im just getting into shape shifters so I did not know if this was a common occurrence .

I got big laugh out of this. And yes, they are fun!
