# Unsolvable Cube

Hello-

I was solving my favorite cube for about the tenth time today when all of a sudden the final algorithm left the top layer scrambled instead of solved. I thought my brain had gone until I was able to solve my other cubes just fine. I am assuming that a cube got twisted out of place without me knowing it. The question is how do I know which one, or do I just need to take the whole thing apart and re-assemble it? And if I do is there a link to a site with good instructions on how to do this?

Thanks!

Do you have a picture of how the top looks right now?

A guess for you:

Solve the cube using the beginner's method, you'll find one corner is off. Just twist it back to being solved, you should be able to do so. Most speed cube corners can be twisted into place.

This is a good idea. I use 2 look oll and I can always tell when a corner is flipped

Same. I usually fix it in OLL, because I can't go forward into PLL otherwise .

Using the beginner's method, this is how the cube looks at the point that it should be solved.

Twist the red-blue white corner so that it's facing up. that should make it solvable

I think the last f2l edge hasn't been inserted yet. The orange-green edge needs to be inserted in order for you go finish f2l.

That was all it took. Thanks much!!
