3x3 ZBLL T 68 algorithm
3x3 ZBLL T 68 algorithm: 13 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 T 68 belongs to the T6 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: R B R; R: B F U; B: B L F; L: U R F. The letters identify colors by their reference faces.
Execute the algorithm
y' R U R2 U' R2 U' R2 U2 R U' R U' R'
The opening is y' R U; the final segment is R U' R'. This version contains 13 face, wide, or slice turns and 1 whole-puzzle rotation.
