How to assemble a Rubik's cube 3x3, 4x4, 5x5 and 2x2: a schematic and video instruction
This item is a known mechanical puzzle, it was invented in 1974 by the Hungarian sculptor Erno Rubik, having patented his invention.
3 by 3( the most common option)
There are many algorithms and schemes how to assemble a Rubik's cube 3x3, understandable even by beginners.
The model consists of 26 multi-colored cubes that can be rotated around their axis, invisible from the outside. The problem is to collect faces consisting of squares of the same color.
Assembly instruction for this device
At first glance, the assembly of the puzzle may seem a complicated process. To better understand, let's see the video:
To get started, it's worth reading some of the terms and titles.
1) The central cube( center) - is indicated in the figure with number 1.
2) The side cube( in other words - the side) - 2.
3) The angle cube( or else the angle) - 3.
The main assembly rule is that,that the front side( or, in other words, the front) should remain unchanged.
The first belt is worth trying to assemble yourself, as the first side has the ability to assemble by any method. The central squares are always relative to each other. Hence, the white side can not coexist with yellow, blue with green, orange with red.
Next, you need to ensure that there is a correct cross from the sides, then collect the corners. In order to assemble the second belt, two formulas are required.
Formula 1.
Formula 2.
It is easy to understand such formulas: turning 1 of formula 1 means that the upper side is turning clockwise, turning 7 of formula 1 turns the front side counter-clockwise. The angle of rotation is 90 degrees.
The assembly scheme for the second belt of the Rubik's Cube 3 on 3 shows the fully assembled side with the first belt - the invisible part on the left. It is worth remembering, the central cube is of the same color, the sidewall has two colors, the angle is one color, and the front side consists of four colors.
Assembling the second belt by the formula
The colors of the planes 2 and 4 will coincide if you change the sideboard to the 0-1 cube. The invisible color of side 2 when assembled according to the first formula is 5. On the third, not yet assembled belt, there are squares 2 and 3. It is necessary to find on the side opposite to the assembled side panel without color 6, rotate the third belt visible on side 6 opposite the same colorthe first belt.
If the color of square 3 coincides with the color of square 5, collect according to formula 2, thus, the side 3 is put in place of the square 0-1.
Next, in order to assemble the puzzle, use the formulas 3, 4, 5.
Formula 3.
Formula 4.
Formula 5.
Rubik's Cube 4x4( 2nd most common variant)
This model is a cube that consists of blockssmaller size, four pieces per rib. For the assembly of the Rubik's 4x4 cube, the same algorithms are used as the 3x3, but they are supplemented by several new formulas. This technology will seem simple for the skilled, able to quickly collect the previous puzzle.
1) The cube must be completely dismantled.
2) At the end of the stage, you need to collect all the centers, that is, four cubes of the same color.
3) The correct arrangement of the colors of the middle is important, since in the 4x4 cube the midpoints are not fixed, as in a 3x3 cube.
4) To perform this step, you need to rearrange the desired middle cubes in front of each other and execute the formula:
Rubik's Cube 2x2( 3rd most popular)
The 2x2 puzzle is a mini version, which also has six colors. But on each side there are four cubes, instead of nine, as in the classic version of the Rubik's Cube 3x3.
Although the figure has fewer combinations to collect it, there are also special schemes and algorithms.

Puzzle 5x5( the most difficult option!)
The most difficult creation of the Hungarian inventor is Rubik's cube 5x5.There are no complications in the assembly, as the instruction for all variants of the arrangement of the elements of this puzzle has long been developed.
