3x3 · 1LLL
3x3 1LLL 49 36 algorithm
3x3 1LLL 49 36 algorithm: 15 turns, opening with R' U' R. 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: none. Upper edges with that color facing up: UF, UR. Reading each side’s top row left to right when facing that side gives F: L B R; R: U R L; B: U U U; L: R U U. The letters identify colors by their reference faces.
Execute the algorithm
R' U' R U' R' U2 F R U R' U' F2 U F R
The opening is R' U' R; the final segment is U F R. This version contains 15 face, wide, or slice turns and no whole-puzzle rotations.
