Step 4 of 4
PLL (last layer)
Place the last-layer pieces with a single algorithm: the top stays yellow, only the pieces move. Look for headlights (two corners of the same colour on one side), full rows and corner-edge blocks, then find the matching case. After the algorithm, a last turn of U lines the layer up if needed: your cube is solved.
The basic situations
Hold the cube as the hint says, then apply the formula. In the app, every formula is animated on a virtual cube.
Aa · three corners
Only three corners move, the edges are solved. Turn U to put the headlights (two corners of the same colour) at the back, then finish with a turn of U if needed.
x R' U R' D2 R U' R' D2 R2 x'→ piece in placeAb · three corners
Only three corners move, the edges are solved. Turn U to put the headlights on the right, then finish with a turn of U if needed.
x R2 D2 R U R' D2 R U' R x'→ piece in placeE · corners in pairs
Only the corners move, swapped in pairs: no side has headlights. Turn U to line the edges up with the centres, and the whole cube (y) if the corners don't look like the picture, then finish with a turn of U if needed.
x' R U' R' D R U R' D' R U R' D R U' R' D' x→ piece in placeF · full bar
One side shows a full row of a single colour. Turn U to put it on the left, then finish with a turn of U if needed.
R' U' F' R U R' U' R' F R2 U' R' U' R U R' U R→ piece in placeGa
Headlights on one side, and a corner-edge pair built elsewhere. Turn U to put the headlights on the left, as in the picture, then finish with a turn of U if needed.
R2 U R' U R' U' R U' R2 U' D R' U R D'→ piece in placeGb
Headlights on one side, and a corner-edge pair built elsewhere. Turn U to put the headlights on the left, as in the picture, then finish with a turn of U if needed.
R' U' R U D' R2 U R' U R U' R U' R2 D→ piece in placeGc
Headlights on one side, and a corner-edge pair built elsewhere. Turn U to put the headlights on the left, as in the picture, then finish with a turn of U if needed.
R2 U' R U' R U R' U R2 U D' R U' R' D→ piece in placeGd
Headlights on one side, and a corner-edge pair built elsewhere. Turn U to put the headlights on the left, as in the picture, then finish with a turn of U if needed.
R U R' U' D R2 U' R U' R' U R' U R2 D'→ piece in placeH · opposite edges
The corners are solved and each edge has to go to the opposite side. Turn U to line the corners up with the centres, then finish with a turn of U if needed.
M2 U M2 U2 M2 U M2→ piece in placeJa
One side shows a full row of a single colour, with a corner-edge block next to it. Turn U to put the full row on the right, then finish with a turn of U if needed.
L' U' L F L' U' L U L F' L2 U L→ piece in placeJb
One side shows a full row of a single colour, with a corner-edge block next to it. Turn U to put the full row on the left, then finish with a turn of U if needed.
R U R' F' R U R' U' R' F R2 U' R'→ piece in placeNa
No headlights, and two corner-edge blocks facing each other diagonally. Turn U so the sides look like the picture, then finish with a turn of U if needed.
R U R' U R U R' F' R U R' U' R' F R2 U' R' U2 R U' R'→ piece in placeNb
No headlights, and two corner-edge blocks facing each other diagonally. Turn U so the sides look like the picture, then finish with a turn of U if needed.
R' U R U' R' F' U' F R U R' F R' F' R U' R→ piece in placeRa
Headlights on one side, and a corner-edge block on the opposite side. Turn U to put the headlights on the left, then finish with a turn of U if needed.
R U' R' U' R U R D R' U' R D' R' U2 R'→ piece in placeRb
Headlights on one side, and a corner-edge block on the opposite side. Turn U to put the headlights on the left, then finish with a turn of U if needed.
R2 F R U R U' R' F' R U2 R' U2 R→ piece in placeT
Headlights on one side, and opposite them a row alternating two colours. Turn U to put the headlights on the left, then finish with a turn of U if needed.
R U R' U' R' F R2 U' R' U' R U R' F'→ piece in placeUa · three edges
The corners are solved and one side is complete: only three edges move. Turn U to put the complete side at the back, then finish with a turn of U if needed.
M2 U M U2 M' U M2→ piece in placeUb · three edges
The corners are solved and one side is complete: only three edges move. Turn U to put the complete side at the back, then finish with a turn of U if needed.
M2 U' M U2 M' U' M2→ piece in placeV
No headlights, two corners to swap diagonally and one corner-edge block built. Turn U to put the block at the front left, then finish with a turn of U if needed.

No headlights, two corners to swap diagonally and one corner-edge block built. Turn U to put the block at the front left, then finish with a turn of U if needed.

The corners are solved and the edges swap with their neighbours. Turn U to line the corners up with the centres, and the whole cube (y) if needed to match the picture, then finish with a turn of U if needed.
