CFOP Step 4 · Permutation of the Last Layer
PLL · All 21 cases
The last step: with the yellow face done, PLL moves every piece of the last layer to its place and the cube is solved. Start with 2-look PLL (6 algorithms) and learn all 21 to do it in one look.
2-look PLL where to start
Step 1, corners: headlights on one side → put them on the left and do the T-perm; no headlights → Y-perm. Headlights on all four sides: skip to step 2.
THeadlights on one side: T-PERMR U R' U' R' F R2 U' R' U' R U R' F'
YNo headlights: Y-PERMF R U' R' U' R U R' F' R U R' U' R' F R F'
Step 2, edges: one of these four leaves the cube solved.
All 21 cases
EDGES ONLY 4 cases
The corners are already in place: only edges move.
CORNERS ONLY 3 cases
The edges are already in place: only corners move.
ADJACENT SWAP 6 cases
Two neighbouring corners swap: one side has headlights.
DIAGONAL SWAP 4 cases
Two opposite corners swap: no side has headlights.
Gs 4 cases
Three corners and three edges cycle, with a 1x2 block travelling together.
