3x3 ZBLL L 70 algorithm
3x3 ZBLL L 70 algorithm: 15 turns, opening with y R U. Case recognition, the complete sequence, and practical execution notes.
Solve the entire last layer in one sequence when its edges are already oriented.
ZBLL L 70 belongs to the L6 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: B L L; R: U B L; B: F R U; L: F F R. The letters identify colors by their reference faces.

y R U R' U R U2 R' U2 R U2 R' U' R U' R'
The opening is y R U; the final segment is R U' R'. This version contains 15 face, wide, or slice turns and 1 whole-puzzle rotation.
