How to Finish the Last Part of the Rubik's Cube

Turn over the Rubik's cube so the unsolved level is on top. The symbol for this level is U for upper level. The other sides are: D for down; L for left; R for right; F for front and B for back. In an algorithm, writing the name of a side means to turn it clockwise, as you are looking at it face on. Written with a 1, it is to be turned counterclockwise, and written with a 2 means turn it two times -- in either direction. For example, the algorithm F F1 F2 means turn the front face clockwise, then counter clockwise, then two times in either direction.

Get a cross showing on the upper level before doing anything else. This does not necessarily mean the edges are in the right place; it just looks that way when you look at U face on. If it is already a cross, skip this step. The only other possibilities are a straight line of the right color across the center of the cube, in which case complete F R U R1 U1 F1. If the proper colors make a right angle, position the cube so the correct colors are on the L and B directions, and do F U R U1 R1 F1. The only other possibility is that only the center square is the right color. In that case, perform both algorithms.

Finish the bottom by getting the corners in the right place. Put the corners you want to switch on the right, and do L U1 R1 U L1 U1 R U2. You may have to do this more than once. Now everything is in the right place. To orientate the corners correctly, do R U R1 U R U2 R1 U2. You may have to do this more than once. To orientate the edges correctly, do R2 U F B1 R2 F1 B U R2. You may have to do this more than once. The cube should now be solved.
