12 sided Rubik s Cube restoration method, how to restore the Rubik s Cube to six sides

This is the solution to the World Champion Bean Nail! In fact, the first few percent of the five Rubik's cubes are the same as those of the third order.

6 colors and 12 sides? Can you tell how many axes the Rubik's Cube is? It's hard to know which kind of Rubik's Cube is with 12 sides alone.

The specific steps to restore the six sides of the Rubik's Cube are as follows:

Tool: Rubik's Cube.

1. First of all, if you want to restore the Rubik's Cube, we must first understand its structure, the Rubik's Cube has a total of 6 colors and 6 sides, generally red, yellow, blue, green, white, orange 6 colors, each side is divided into ** block (6 blocks in the middle), corner blocks (8 blocks in 4 corners) and side blocks (12 blocks in the middle of 4 edges). Among them, there is only 1 face, and they are a fixed structure, so if the block is red, then the other reds must be concentrated on this surface. And the red block is always opposite the orange block (as the international standard dictates).

The edge blocks each have 2 faces and 2 colors, and the corner blocks each have 3 faces and 3 colors.

2. Next, we will use letters to represent each face, and then return its bottom edge to position (also known as the bottom cross, the process of correct restoration of the bottom four edges) and the bottom corner return (restore the first four corner blocks of the Rubik's Cube): Formula 2-1: (rur'Equation 2-2:

f'u'f) Align the white corner blocks.

3. The middle edge is homebound (the step of restoring the four edges in the middle layer of the Rubik's cube): Formula 3-1: (u'f'uf）（uru'r'Equation 3-2: (uru'r'）（u'f'uf）。

4. The top edge position (also known as the top layer frame cross, the top surface color of the top four edges is the same as the color of the top center block): Formula 4: F (rur'u'）f'Top Corner Position (the step in which the top color of all four top corners of the Rubik's Cube is adjusted to the top surface):

Equation 5-1:r'u2rur'ur equation 5-2: u'ru'u'r'u'ru'r'。

5. Apex corner homing (the other two colors of the four vertex corners of the face position and the color of the center block of the corresponding face are the same color): Formula 6: rb'rf2r'brf2r2。

6. The apex is in place (the color of the other side of the four vertex edges that have been in place is the same color as the color of the center block of the other four faces): Equation 7: (ru'r）（urur）（u'r'u'r2）。

The 12-color five-color cube has a total of one state of change, and the six-color cube has a kind of change.

1. The first layer is skipped, and the second layer of Kaihong Annihilation begins with reference to the 3-order Rubik's Cube simple Dan absolute pure solution, which can be restored to only the top layer, for the sake of convenience, it is necessary to memorize several transfer methods first;

2. The right side is rotated 90 degrees counterclockwise;

3. The upper side is rotated 90 degrees counterclockwise;

4. Turn 90 degrees counterclockwise on your side;

5. The right side is rotated 90 degrees clockwise. It's just the opposite of 1;

6. Turn the surface of the upper mold 90 degrees clockwise. It's just the opposite of 2;

7. Turn 90 degrees clockwise on your side, just the opposite of 3;

8. The lower right side is 90 degrees counterclockwise;

9. The lower right side is 90 degrees clockwise, just the opposite of 7;

Next, we will officially start to turn to the top layer of the five Rubik's Cubes, and first let the edges return to their positions.

Formula: 123-564

The notation of the formula is very simple, that is, take the 4 of 123456 ** to the end. There is no edge on the top surface, and there is no corner block.

After running the formula, it will become a b2 situation, and it will be placed according to the b2 position.

To restore one side of the Rubik's Cube, you need to make a cross first, and then there will be three situations, and three different formulas are used according to different needs, as follows:

1. First of all, restore a cross, and 4 edges of the same color form a cross pattern.

2. The reduction corner block will encounter the situation of the missing block in the lower left, formula: d, l, d', l', as shown in the figure below.

4. The situation of the missing block in the lower right corner is opposite, the formula: d', r', d, r, as shown in the figure below.

5. In the case of the same block missing in the lower right corner, the formula: r' d, r, d', r', d, r, as shown in the following figure:

The dodecahedral Rubik's Cube tutorial is as follows:

First, turn the center of this face into a cross; Return the top corner of this face to its place. Generally, when restoring the Rubik's Cube, the bottom surface will be restored first, and the remaining part will be restored after the bottom surface is put together. First, select a surface as the bottom surface, determine the center color block of this surface, you will know what color this surface is, and pay attention to the side while determining the bottom surface.

The color of the center of the side should also be the same as the color of the edge of the bottom edge of the side. This step is a bit complicated at the beginning, but it is relatively simple when it comes to actual operation, so there is no specific formula for this step.

When turning the bottom edge, pay attention to the color of the other side of the edge, find the same color as the side center color block and the side color of the edge, and then rotate the edge to the same surface as the center color block, so that it will be easier to find the trick.

After the cross of the bottom surface is turned, the top corner of the bottom surface is also turned out, that is, the top corner of the top surface is returned to the family leakage, and the first layer is restored after this step is completed. After restoration, the bottom surface is restored, and the bottom layer of the side around the bottom surface is also restored. The color of the bottom layer of the side should be the same as the center color block of the side.

There are two formulas for this step, which are divided into five cases. The formula for the homing of the top corner of the bottom surface is relatively simple, and the first formula is (r u r'), equation two is (f'u'f）。These two formulas can be used separately, in combination, and sometimes repeatedly, depending on the situation.

The 4-sided Rubik's Cube restoration method is as follows:

When the fourth-order Rubik's cube is restored, it is to first complete the six-sided Yu Zhichang center block, and then complete 12 pairs of edge blocks, and use the third-order Rubik's cube reduction method to restore the Rubik's cube, and finally use a special formula to deal with special situations when there is a special situation.

When the fourth-order Rubik's Cube is restored, first observe whether the color matching is yellow on the top and white on the bottom, blue on the front and green on the back, orange on the left and red on the right, and then rotate the center block on the top and bottom and left and right according to this fiber matching color when the first center block is completed.

When restoring, first put together the yellow and white two-sided center block, and then restore the blue, red, green, orange four-sided center block, you can also complete the yellow center block first, keep the yellow center block unbroken, and then complete the white center block.

The formula used is rw u rw'、rw u' rw'、lw' u lw、lw' u' lw、rw u'2 rw'、lw' u2 lw。

Then it is to complete 12 pairs of edges, hold a ridge formula to complete 12 pairs of edges, and the middle part is to flip the edges on the right side in situ, and the formula used is r u r' f r' f' r，uw' （r u r' f r' f'r) uw, do a counter-edge formula, and combine the counter-edges together with the formula r u r' f r' f'r to turn.

Finally, according to the third-order Rubik's Cube reduction method, the formula for special cases is the edge exchange formula UW2 ( MR2 U2 )2 MR2 UW2, and the single edge turning formula RW U2 CR (RW U2)2 RW' u2、lw u2 rw' u2 rw u2 rw'、u2rw'。
