Hold the cube with one face as the front and one as the top
Solve one face completely
Make the top layer corners match the side colors
Use the algorithm R U R’ U R U2 R’ to permute the top corners
If needed, repeat the algorithm until all top corners are in the correct positions
Turn the top layer to place a solved corner at the front-right-top position
Use the algorithm U R U’ L’ U R’ U’ L to orient the remaining top corners
Repeat the orientation algorithm until the cube is solved
If a step breaks a solved part, adjust the top layer and continue
Practice the algorithms until they can be done smoothly
