What is the minimum number of turns needed to solve a rubik's cube with one edge piece faced the wrong way on the 3rd layer?



1 Answer 1


Not possible.
For one cubelet to be off like that indicates that the cube was misassembled. See here - any legal rotation or combination of rotations that involves flipped edge cubes will result in an even number of flipped edge cubes.

    $\begingroup$ @BeastlyGerbil - why spoilerize this? The situation is impossible, and not making that clear immediately does not seem reasonable. $\endgroup$ Jan 3, 2017 at 17:42
