The first solution: introduction

I think that one of the much interesting things of Cube is to solve it. Now I will explain you one of the methods I found on Internet.
The resolution method that I will explain is constituted of three macro-steps. I will use the notation standard of the world of the cubists. The movements base are:

• R: right face clockwise;


• L: left face clockwise;


• F: front face clockwise;


• B: back face clockwise;


• U: up face clockwise;


• D: down face clockwise.

The counter clockwise turns are marked with a ('): R', L', F', B', U', D'.
Double turns are marked with a 2: we don't write RR but R2.

During the explanation it will be spoken about several the elements of the cube, that I identify in this mode:

• Cubi to the chines (edge cubes): the cubes to half of every chine of the cube of Rubik, ce are twelve, everyone of which have the colors of a brace of faces differenti;
• Cubo center them (center piece): it is the square situated in means of every face, ce are six, everyone has the color of one faccia;
• Cubi to the angles (corner cubes): they are the cubes situates you to the angles of the cube of Rubik: they are eight, everyone has the colors of three faces on different aces.
• Strato (layer): posizionando the cube of Rubik on a table three layers can be noticed (plans) of cubes. That more up first layer or advanced layer will be called, that one centers them according to layer or median layer, that more low third layer or layer inferiore.

Il introduced method of resolution hour is that layer for layer (layer by layer method), that the first one consists in resolving in succession, the second and the third party strato.

The first solution: first layer

Partiamo always from the same face, è più easy and us permetterà to save time if we will have to resolve it various times. In this case we decide to always leave from the face white woman. Not è sufficient to complete the face white woman but it must make it in way that the cubes are arranged so as to subsequently to be able to complete the other faces. Lasceremo però a cube to the empty angle that us sarà profit later on. In order to simplify the construction of this primo strato we will divide it in two passi.

Primo passo Bisogna to design to a cross white woman having cure that the colors of four pieces to sides coincide with the colors of pieces center them of same sides. In this modo:

Secondo passo must hour to arrange three cubes white men to the angles. This step è a po' più difficult poiché the cross must be maintained. These are the base algorithms: F D F ', R' D' R and R' D R F D² F '. These moved maintain always the cross begin them and concur to arrange an angle that is found in one of the three possible positions, rispettivamente.

F D F'	R' Of R	R' D R F D2 fine F'

Alla must have this situazione:

Se are wanted to be resolved the cube in a good time must train themselves in this step. Può to save much time in this first part of the risoluzione.

The first solution: second layer

Per according to layer it must put the cube sottosopra. Hour we can take advantage of the fact to have left a cube to the empty angle for fastly posizionare three cubes to the chines of the median layer. There are two simple and symmetrical movements that will allow us to make ciò (it turns the cube like in figure if necessary): R U' R' and the U L.

R U' R'	L' U L

In this way can be posizionare three cubes to the chines of according to layer. Hour the cube would have to up appear così.

Rigiriamo of the cube with the side white man and posizioniamo the last cube to the angle left empty in the first layer. We proceed as we have made for the other cubes the angle but making attention not to remove nobody of the tre cubi to the spigoli posizionati ones well in according to layer. Hour we must use one of following the two algorithms (symmetrical): Of R' D R D F D' F' and D L Of D' the F' D F.

D' R' D R D F D' F'		D L Of D' the F' D F

Ora we have completed first due strati if all è gone bene.

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.
