R = Clockwise turn of right face
R' = Counterclockwise turn of right face
This is the third and final step to solving the Rubik's Mini Cube. In this step you will be untwisting the final pieces in the top layer.
This becomes a little tricky, because you need to do these following moves in pairs. First you rotate some corner piece; then rotate another corner in the OPPOSITE direction. Don't be scared if the cube looks messed up after one of the sequences. If you perform the other sequence without moving the cube then it will undo itself. Between sequences, just turn the UP face until a corner which needs rotation in the other direction is in the upper right hand corner. If it doesn't look like there is a corner that needs to be twisted the other way, just twist anything. Eventually you'll get it.
This it! For a bigger challenge, try the full sized Rubik's Cube
