3x3 ZBLL U 41 algorithm
3x3 ZBLL U 41 algorithm: 9 turns, opening with x' R2 D2. Case recognition, the complete sequence, and practical execution notes.
Solve the entire last layer in one sequence when its edges are already oriented.
ZBLL U 41 belongs to the U4 group in ZBLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. 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 F F; R: R R L; B: U B U; L: L L R. The letters identify colors by their reference faces.
Execute the algorithm
x' R2 D2 R' U2 R D2 R' U2 R' x
The opening is x' R2 D2; the final segment is U2 R' x. This version contains 9 face, wide, or slice turns and 2 whole-puzzle rotations.
