3x3 1LLL 12 5 algorithm
3x3 1LLL 12 5 algorithm: 12 turns, opening with y' R' U'. Case recognition, the complete sequence, and practical execution notes.
Solve this specific last-layer orientation and permutation in one sequence after completing the first two layers.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UBR. Upper edges with that color facing up: UF, UR. Reading each side’s top row left to right when facing that side gives F: U B L; R: U R L; B: F U R; L: U U B. The letters identify colors by their reference faces.

The opening is y' R' U'; the final segment is U' R S. This version contains 12 face, wide, or slice turns and 1 whole-puzzle rotation.
