3x3 ZBLL T 30 algorithm
3x3 ZBLL T 30 algorithm: 17 turns, opening with R' U2 R. 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 30 belongs to the T3 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: F R F; R: R B U; B: B L B; L: U F L. The letters identify colors by their reference faces.
Execute the algorithm
R' U2 R U R' U R F U R U2 R' U R U R' F'
The opening is R' U2 R; the final segment is U R' F'. This version contains 17 face, wide, or slice turns and no whole-puzzle rotations.
