2x2 CLL U 3 algorithm
2x2 CLL U 3 algorithm: 10 turns, opening with y2 F R. Case recognition, the complete sequence, and practical execution notes.
Solve the final four corners of the 2x2 after completing the first layer.
CLL U 3 belongs to the U group in CLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: B B; R: L R; B: U U; L: L R. The letters identify colors by their reference faces.

The opening is y2 F R; the final segment is U' R' F. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
