2x2 CLL Pi 6 algorithm
2x2 CLL Pi 6 algorithm: 10 turns, opening with F R U. Case recognition, the complete sequence, and practical execution notes.
Solve the final four corners of the 2x2 after completing the first layer.
CLL Pi 6 belongs to the Pi group in CLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Reading each side’s upper corner stickers left to right when facing that side gives F: L U; R: F B; B: U L; L: U U. The letters identify colors by their reference faces.
Execute the algorithm
F R U R' U' R U R' U' F'
The opening is F R U; the final segment is R' U' F'. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
