Start solving the last layer making a yellow cross on the top of the cube. It doesn’t matter if the pieces are not on their final places so we don’t have to pay attention to the colors of the sides.
We can get three possible patterns on the bottom.
- When you see a dot you have to apply the algorithm three times. If you have a yellow “L” shape then only twice, holding the cube in your hands as seen on the image below.
- In case of a horizontal line you just have to execute the permutation once.
Use this algorithm to go from one state to the other:
