3x3 · PLL
3x3 PLL Ja algorithm
3x3 PLL Ja algorithm: 10 turns, opening with y2 x R2. Case recognition, the complete sequence, and practical execution notes.
Permute the last-layer pieces while preserving their orientation and the first two layers.
Ja belongs to the Adj Swap 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: L L F; R: R R R; B: B B L; L: F F B. The letters identify colors by their reference faces. Piece locations (position ← home piece): UFL ← UBL, UBL ← UFL, UF ← UL, UL ← UF.

The opening is y2 x R2; the final segment is Rw U2 x'. This version contains 10 face, wide, or slice turns and 3 whole-puzzle rotations.
