3x3 ZBLL L 18 algorithm

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

ZBLL L 18 belongs to the L2 group in ZBLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL, 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 F F; R: U R R; B: B B U; L: F L B. The letters identify colors by their reference faces.

Execute the algorithm

y F R' F' Rw U R U' Rw'

The opening is y F R'; the final segment is R U' Rw'. This version contains 8 face, wide, or slice turns and 1 whole-puzzle rotation.
