3x3 Anti-PLL Pure algorithm
3x3 Anti-PLL Pure algorithm: 12 turns, opening with M' U2 M. Case recognition, the complete sequence, and practical execution notes.
Solve this Anti-PLL last-layer configuration, checking its flipped-edge pattern as well as its permutation.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL, UBL, UBR. Upper edges with that color facing up: none. Reading each side’s top row left to right when facing that side gives F: F U F; R: R U R; B: B U B; L: L U L. The letters identify colors by their reference faces.
Execute the algorithm
M' U2 M U2 M' U' M U2 M' U2 M U
The opening is M' U2 M; the final segment is U2 M U. This version contains 12 face, wide, or slice turns and no whole-puzzle rotations.
