3x3 · 1LLL
3x3 1LLL 15 43 algorithm
3x3 1LLL 15 43 algorithm: 10 turns, opening with Fw U Fw'. 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: UFR. Upper edges with that color facing up: UL, UR. Reading each side’s top row left to right when facing that side gives F: R U F; R: R R U; B: B U U; L: L F U. The letters identify colors by their reference faces.
Execute the algorithm
Fw U Fw' R' Fw R U' R' Fw' R
The opening is Fw U Fw'; the final segment is R' Fw' R. This version contains 10 face, wide, or slice turns and no whole-puzzle rotations.
