Cube

6: Solve the up corner block

Restore the U(up) 4 corner blocks, your goal:

This step does not need to care the up edge blocks, this step only needs 1 formula RB’RF2R’BRF2R2. First find a face, the color of the front of his two corner blocks is the same, put him in front, use this formula to restore the up corner block. If you can not find such a face, you can get such a face by run this formula.

• Case1 The up layer already has a face with the same color of two corner blocks at front. You can use the following formula to restore the top corner block.

• Case2 The up layer can’t find such a face, and you can get such a face directly by doing this formula.

So far, you have learned 8 of the 9 formulas, and you can restore the Rubik’s cube by learning 1 formula. :)
