3x3 ZBLL U 22 algorithm
3x3 ZBLL U 22 algorithm: 14 turns, opening with y' R2 F'. 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 22 belongs to the U2 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 B B; B: U F U; L: L R B. The letters identify colors by their reference faces.
Execute the algorithm
y' R2 F' R U2 R U2 R' F U' R U R' U' R
The opening is y' R2 F'; the final segment is R' U' R. This version contains 14 face, wide, or slice turns and 1 whole-puzzle rotation.
