3x3 ZBLL T 31 algorithm
3x3 ZBLL T 31 algorithm: 10 turns, opening with y2 Rw 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 31 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 B F; R: R R U; B: B F B; L: U L L. The letters identify colors by their reference faces.
Execute the algorithm
y2 Rw U' Rw U2 R' F R U2 Rw2 F
The opening is y2 Rw U'; the final segment is U2 Rw2 F. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
