3x3 COLL L 6 algorithm
3x3 COLL L 6 algorithm: 9 turns, opening with y Rw U2. Case recognition, the complete sequence, and practical execution notes.
Solve the last-layer corners with the last-layer edges already oriented; edge permutation may remain.
L 6 belongs to the L group in COLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL, UBR. Upper edges with that color facing up: UF, UL, UB, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: R F; R: U B; B: L U; L: R F. The letters identify colors by their reference faces.
Execute the algorithm
y Rw U2 R2 F R F' R U2 Rw'
The opening is y Rw U2; the final segment is R U2 Rw'. This version contains 9 face, wide, or slice turns and 1 whole-puzzle rotation.
