Rubik's Cube for Beginners
Step 6: Permute Last Layer Corners
Turn the top layer until exactly two of the corners are in their correct place. To the right is an example of a corner in the correct place. See how the color of each sticker of the corner matches the color of the center that sticker is on?
Now you will have one of the two states below. Either the two correct corners are adjacent to each other (and therefore the two that need to be swapped are adjacent too), or the two correct corners are diagonal from each other (and the two that need to be swapped are diagonal too).
The corners that need to be swapped have arrows pointing to them. Therefore, the two correct corners in State 1 are the two on the right side, and the two correct corners in State 2 are the bottom-left and top-right ones. (Actually for state 2, the algorithm would still work if the two correct corners were at the top-left and bottom-right instead.)
Note:Remember that 'B2' is to turn the BACK side twice, not the bottom. The correct letter to turn the bottom side is 'D.' ('D' stands for "down.")
|State 1||State 2|
|R2 B2 R F R' B2 R F' R
Then do U to correctly align the four corners.
|Do the algorithm for state 1 and it should look like state 1.|
When you are done, your cube should look like this:
