Orienting The Last Layer


The graphics show the top view of the last unsolved layer (the U side). The black squares and the short line segments at the sides show the color of the last layer (the U side). For some positions, there are several algorithms, all doing the same thing. Choose among them according to your preference. The numbers in brackets show the number of moves for each algorithm in four different countings (face moves, quarter moves, slice moves, and antislice moves). More details and notation explanation can be found in the legend or at the bottom of this page.
