Rubik's Cube for Beginners
Step 7: Permute Last Layer Edges
Yay! Last step! And this is proabably the easiest step too! The states are very straightforward.
There are 4 possible states for permuting the edges. Two algorithms are needed. The algorithm for state 2 is almost the same as the one for state 1, except for the second turn and second-to-last turn.
Be careful on the B and B' turns. Don't mix those two up. Remember that in the notation used, you pretend you are looking at the face you are turning to determine which way is clockwise and which is counterclockwise. Therefore, a B will look counterclockwise from the front, but if you were to turn the cube around and look at it from the back, the move would be clockwise. The same thing with B'.
| State 1 | State 2 | State 3 | State 4 |
|---|---|---|---|
| R2 U F B' R2 F' B U R2 | R2 U' F B' R2 F' B U' R2 | Do an algorithm for state 1 or 2 and it should look like state 1 or 2. | Do an algorithm for state 1 or 2 and it should look like state 1 or 2. |
You are done with the cube! Congratulations!!! Now you can go impress your friends and family and teachers!!!
WARNING WARNING WARNING (my previous math teacher said that a lot, and according to my friends who have him this year, he still does =D): Don't play with it in class (assuming that you are in school) unless you have one of those nice teachers. I got my cube confiscated twice. :D One was in 7th grade, because my friend was playing with it after school in my teacher's class when he was supposed to be working. As of right now (10/2/07), I can't remember when the second time was.
If all you wanted was to be able to solve the cube, get this solution memorized and your done! If you want to get faster, check out the Get Faster page for more information.
