The first solution: third layer

Per to resolve the last layer we turn of new the cube sottosopra with the incomplete face sopra.

Primo step: to create croce an Hour we must construct a cross to the opposite side to that one begins them (white man), without preoccuparci of the order of the cubes that form the cross. They are necessary an algorithm and its inverso.

U F R U R' U' F'

F U R U' R' F

Se we do not have blue cubes over (to part the piece centers them) we must use one of the algorithms before (does not import which scegliere).

Secondo step: to orient croce the following algorithm has this effect: the frontal cube of the cross does not move and the others three move in sense orario.

R U2 R' U' R U' R'

Se want that the three cubes turn in counter-clockwise sense apply to two times the algorithm or the inverse algorithm R U R' U R U2 R'
an other solution consists in turning the face over and putting an other cube in the place of the frontal cube. È always possible to only once apply the previous algorithm, all which must be made è to try as the cube and its advanced face must be ruotati.

Terzo step: at this rate to posizionare the cubes to angoli the objective è to put every cube to the angle to its final place but without preoccuparsi for the moment of the guideline. As an example the blue-green-red chine must not necessarily go in its final place but turned good on if stesso.

L' U R U' L U R' U'

Se we wanted to make to turn the angles in counter-clockwise sense può to apply to the algorithm two times or to apply to the inverse algorithm (U R U' the U R' U).
Ripetiamo this step many times how many necessary ones (vedrà that two times è sufficiente).

Quarto step: to orient the cubes to angoli the last algorithm è a po' along but you will notice that you know già before parte.

R U2 R' U' R U' R' the U2 L U the U L

Ripetiamo this step many times how much è necessario.
