Algorithm: Ri Di R D
Goal: To complete the top face while also forming letter ‘T’s in all four front, right, left, and back faces.See below :
How to do it:
1) You need to find the four corner pieces with a color of the Top face (white&red&blue, white&red&green, white&green&orange, white&orange&blue).
2) Once you find one, place it directly below its correct position and perform Algorithm 2.
3) Repeat Algorithm 2 either once, thrice, or five times until the corner piece gets in to the right position.
