I couldn't find a topic that already addressed this issue, so I come to you looking for assistance with my MF8 (I believe) crazy 2x3x3.
While playing with this puzzle, aside from serious attempts to solve it, I have performed a couple of very strange moves that I am not certain are meant to be done to it. Obviously, if the moves were performed, they can be reversed. My thoughts were that perhaps it has caused a parity error. I have solved normal 2x3x3 puzzles a few times, and I have taken the same approach, using the same algorithms that I have established, but still can't solve it. I have attributed this to the possibility that perhaps performing this seemingly unintended move has caused an additonal obstacle for me.
The move I am talking about is rotating the middle slice 90 degrees, and then rotating either the top or bottom faces 180 degrees. I've included a couple pictures to help describe my inquiry.
Perhaps it makes no difference and I'm just not thinking hard enough!
