I am Bob Burton, Rubik's Cube Expert, and I am teaching you how to solve a Rubik's Cube. We are now on our last step, permuting the last layer corners. To do this we look for a set of three pieces that form a corner of a Rubik's cube, where the two edges match the corner piece. We put that in front of us so that were going to rotate cubes starting with the rightmost piece. To do this, we put the right side down, front side clockwise, right side down. We move the back twice, put the right side up, front counterclockwise, right side down, back twice, and right twice. Sometimes we may need to do this twice, since this is also a three cycle. We well do this again; right side down, front side clockwise, right side down, back twice, right side up, front side counterclockwise, right side down, back twice, right twice. We have now solved a Rubik's Cube. There is also one more possible case where sometimes we don't have those three pieces next to each other that we need. If this is the case, we can look at any side of the Rubik's cube and do that algorithm; right side down, front clockwise, right side down, back twice, right side up, front counterclockwise, right side down, back twice, right twice. We then, again, put the corners, the solved corner, in the front left and do the algorithm we know; down, front, down, back twice, up, fix the front, down, back twice, right twice. You now know how to solve a Rubik's Cube from any state. Now that we know all the steps to solve a Rubik's Cube, let's solve one from start to finish.
