3x3 1LLL 9 29 algorithm
3x3 1LLL 9 29 algorithm: 12 turns, opening with y2 R' F. 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: UBL. 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 R F; R: U B R; B: U U B; L: L U B. The letters identify colors by their reference faces.
Execute the algorithm
y2 R' F R U' M' U F' Rw U Rw' U' M
The opening is y2 R' F; the final segment is Rw' U' M. This version contains 12 face, wide, or slice turns and 1 whole-puzzle rotation.
