3x3 · PLL
3x3 PLL Z algorithm
3x3 PLL Z algorithm: 9 turns, opening with M' U' M2. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
Z belongs to the EPLL group in PLL.
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: UF, UL, UB, UR. Reading each side’s top row left to right when facing that side gives F: R B R; R: B R B; B: L F L; L: F L F. The letters identify colors by their reference faces. Piece locations (position ← home piece): UFR ← UBR, UFL ← UFR, UBL ← UFL, UBR ← UBL, UF ← UB, UB ← UF.
Execute the algorithm
M' U' M2 U' M2 U' M' U2 M2
The opening is M' U' M2; the final segment is M' U2 M2. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
