Algorithm 3a: Ui Li U L U F Ui Fi
Algorithm 3b: U R Ui Ri Ui Fi U F
Shuffle Algorithm: L Ui Li Ui
Goal: To complete two bottom lines on all four front, right, left, and back faces. Like below:
How to do it:
1) Turn the cube upside down so that the white face is now the bottom face and the yellow face is now the top face.
2)Find an edge piece located on the Top face that does not have any Yellow in it.
Note: Sometimes all edge pieces may have yellow in them. Follow the Shuffle Algorithm and an edge piece with yellow will appear.
3) Flip the top face to align that edge piece with its corresponding color then make it as your Front face. In my example below, I aligned it to the blue face which then became my Front face.
Part 2
4) Look at the 2nd color of that edge piece. In my case, it’s orange. You will find out that that color is either the color of your left face or right face. In mine, orange is the color of my left face.
If it is the color of your left face, do Algorithm 3a
If it is the color of your right face, do Algorithm 3b
5) Repeat these steps until you form the Goal.
