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.
