How to assemble a rubble cube

Every eighth resident of the planet at least once tried to collect Rubik's cube. The puzzle seems to be very simple in appearance, but has a huge number of combinations of moves. Lie joke, the number of permutations for a classic cube - 3 * 3 * 3 - 8! * 3 ^ 8 * 12! * 12 ^ 3/12 \u003d 4.3 * 10 ^ 19. How to become a winner in a logical game and collect a cube?

The prototype of a successful puzzle was invented in 1974 by the Hungarian industrial designer and architect, the teacher Erno Rubik. Its first name was "wonderful cube". Consisted a puzzle of 54 external faces and had a view of Cuba 3 * 3 * 3. Developed her Rubik for development in his student spatial imagination. When all the edges of the cube for better slip and rotation among themselves, without breaking the overall design, they were connected inside a cylindrical fastening mechanism, the scientific manual has become a toy that rapidly increasing its popularity.

If you decide to make a riddle's riddle of a cube, then to begin with, consider it: what color with what borders, what colors do not intersect at all. Many are at once in a hurry to confuse her to start collecting faster. Starting a riddle solution, you need to decide on the terms and locations of the parties, as well as small tricks:

The white side is physically can not coherent with yellow, green with blue, and orange with red.
The middle cube of each side is called the center. Central cubes have only one color.
Cubes, on perpendicular intersection (90 °) of which the center is located, are called side and have two colors.
Cubes located in the corners from the center are called angular and consist of three colors.
You need to choose the color from which the puzzle assembly will begin. The masters prefer to start with white and finishing the assembly yellow. But this is not so substantial. The main thing is that the selected color, which is going first, was on the upper side of the cube. Do not twist the puzzle in your hands, confuse even more, - Rotate the face. The face is a rotating triple, consisting of two angular and one side cubes.
The side of the cube with which the assembly begins is called the top. The side that looks at you when assembling - front. The opposite is rear, and the sides, respectively, right and left.

The main thing in solving the puzzle of the Rubik cube is not to collect a toy in colors, but to put each element on its correct, right place in space.

Assembling upper cross. Rearming the edge of the cube with different combinations, you must ensure that on the upper side of the cube to collect a cross (central cube and all lateral). Keep track of the correct location of the side cubes. For example, if the upper side of the cube is chosen green, the side green-yellow cube must be on the side where the central cube has yellow.

Rule of compensation: Any rotation of the faces leads to the destruction of any part. In order for this destruction to minimize, you should always make composite turns. For example, if you made a turn of the face down, then you must make a turn upstairs.

Assembling angular cubes of the upper side. When assembling corner cubes, the main thing is not to break the already collected upper cross. To do this, we use the rule: "omit - we turn - raise." That is, the side face of the upper side of the cube (corridor) omit down, scroll down the lower row (basement) and raise the same "corridor" up. With the right assembly of angular cubes of the upper side, you must have the entire top layer of the puzzle.

When the upper side is properly assembled and all cubes correspond to their color planes, turn the ruby \u200b\u200bcube and work with the bottom - the basement. It is necessary to move all cubes-sides to legitimate places from the bottom side, which must be connected to each other side. Since the bottom side, which at this stage becomes the top, you can easily rotate, not afraid to break any already folded correct combination, the necessary cubes are summing up to the desired side and also use the rule "omit - we turn - raise" in the interpretation "raise - we raise In the opposite side of the place you need - omit. "

Putting the side cubes of all sides, except for the bottom, in their place, it turns out to collect two layers correctly - the upper and medium. To assemble the lower layer, you need to carry out the following combinations:

Collect cross. The cross may not be correct, that is, the second colors of the side cubes may not coincide with the color of the central cube of the adjacent side.
Collect all the bottom cubes, while not only side, but also angular elements can not stand in their places.
To a certain combination to put cubes on their rightful place.

All combinations are schematically represented on website.

For all the time of the logical game, more than 350 million pieces were released, and now there is even a virtual cube for Windows in the computer age. At the assembly of Rubik's cube for the first time you can get away from the same day. When you still get a riddle, you will be very pleased with yourself. And before friends will boast.
