3x3 ZBLL U 3 algorithm
3x3 ZBLL U 3 algorithm: 9 turns, opening with y2 R2 D. 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 3 belongs to the U1 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: L L F; R: R R F; B: U F U; L: R B B. The letters identify colors by their reference faces.
Execute the algorithm
y2 R2 D Rw' U2 Rw D' R' U2 R'
The opening is y2 R2 D; the final segment is R' U2 R'. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
