3x3 ZBLL Pi 67 algorithm

Solve the entire last layer in one sequence when its edges are already oriented.

ZBLL Pi 67 belongs to the Pi 6 group in ZBLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: none. 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 U; R: F F B; B: U B L; L: U R U. The letters identify colors by their reference faces.

Execute the algorithm

y R U2 R' U' R U' R2 U' R U' R' U2 R

The opening is y R U2; the final segment is R' U2 R. This version contains 13 face, wide, or slice turns and 1 whole-puzzle rotation.
