The restoration methods of the third-order Rubik's cube can be divided into the following categories:

1. Layer-by-layer reduction: layer-first method, CFOP and its derived VH, etc. In essence, the method of layer-by-layer restoration is based on the optimization of the layer first (step merger).

2. Block construction: Petrus and bridge block construction are a technique of the smallest step, which mainly applies the method of block construction ideas, and generally has fewer restoration steps.

3. Group reduction: EO-line (this method is a combination of group reduction and layer-by-layer) A class of methods produced by group theory in the part of the hue reduction in the blind twisting method.

4. Separation of edges and corners: edge-first method, angle-first method.

5. Block-by-block cycle: The four-step blind twisting method, M2R2, and the two-step blind twisting method are all block-by-block cycle ideas to restore the third-order Rubik's Cube.

The Rubik's Cube starts. Rubik Erno, a Hungarian professor of architecture and sculpture, made the first prototype of the Rubik's Cube himself in order to help his students understand the composition and structure of the cube of space, inspired by the sand and gravel of the Dama Lenau River.

In 1974, Professor Rubik invented the first Rubik's Cube (then known as the Magic Cube) and in 1975 received the Hungarian patent number HU170062, but did not apply for an international patent. The first Rubik's Cube was sold in toy stores in Budapest in 1977. Unlike Nichols' Rubik's Cube, Professor Rubik's parts are snapped together like a tenon, not easily separated by external forces, and can be crafted from any material.

In September 1979, Ideal Toys brought the Rubik's Cube to the world, and in 1980 it was unveiled at international toy fairs in London, Paris and the United States.

After the exhibition, Ideal Toys changed the name of the cube to RUBIK'S Cube, in May 1980, the first batch of Rubik's cubes were exported in Hungary.

2. Introduction. The Rubik's Cube is called the Magic Cube in Taiwan, the Twisted Dice in Hong Kong, and the Rubik abroad's cube. Invented in 1974 by Hungarian architecture professor and sculptor Ernor Rubik, the mechanical educational toy was originally called the Magic Cube and was sold by Ideal Toys in 1980 and changed its name to Rubik's cube。

The detailed tutorial of the third-order Rubik's Cube restoration is as follows:

1. Right reverse, upward reverse, forward reverse, upward reverse.

2. Right reverse, downward reverse, right converse, downward transverse.

3. The formula for the first case is: (up, right, up, right, up

The second case formula for withering is: (upside reversal, forward reversal, upward order, front order, front order, right direction, right direction, right direction).

4. Forward Shun, Right Shun, Shang Shun, Right Reverse, Upper Reverse, Forward Reverse.

5. Right Shun, Shang Shun, Right Reverse, Shang Shun, Right Shun, Shang Shun, Shang Shun, Right Reverse.

6. Ascending, right, up, left, up, right, up, left.

7. Right reverse, downward reverse, right shun, lower shun.

Restoring the Rubik's Cube can be done in seven steps:

1. Make a green cross on the top floor. Available formulas: (right reverse, upward straight, forward reversed, upper inverse) (remarks) here reverse refers to counterclockwise, and forward refers to the forward pointer. The Rubik's Cube is divided into up, down, left, right, front and back, so the above situation will occur.

First, find the green in the center, then use this green as the center, find the four green edges around him, and finally put together a green cross. If you want to spell this green cross, you have to find it from the green edge in the middle.

2. Return the green corner blocks. Available formulas: (Right Reversed, Reverse Down, Straight Right, Straight Down) The formula can be repeated multiple times.

3. Make the middle edge block belong to the Changzhou position. This can be both.

The formula for the first case is: (Ascend, Right, Ascend, Right, Ascend, Ascend, Forward, Ascend, Ascend).

The formula for the second case is: (upside down, front reversal, upward straight, forward straight, upper straight, right straight, right inverse, right inverse).

4. Return the edges of the top layer to their positions. Available formulas: Forward Straight, Right Straight, Up Straight, Right Inverse, Up Inverse, Forward Inverse.

5. Return the top edge block. Available formulas: Right Straight, Up Straight, Right Inverse, Up Straight, Right Straight, Up Straight, Up Straight, Right Inverse.

6. Return the corner blocks of the top layer. Available formulas: Ascend, Right, Up, Left, Left, Right, Up, Left.

7. Return the top corner block. Available formulas: right reverse, downward reverse, right straight, downward straight, can be repeated multiple times.

At this time, you must pay attention to holding the Rubik's Cube, which is the red side in front, turn the top layer clockwise (up and down), and then turn the corner that needs to be rotated to the upper right position. Follow the formula a few more times, when doing the steps, the lower level may be messy, don't worry, just continue to do it according to the formula.

There are many ways to restore the third-order Rubik's Cube, usually the simpler the better, the following introduces a third-order Rubik's Cube restoration tutorial, which is relatively simple and fast, and the specific steps are as follows:

Tools: You need to prepare a third-order Rubik's Cube.

1. First of all, build the top layer of cross flowers, complete the restoration of the bottom layer, and complete the return of the edges of the second layer.

2. Restore the third layer of the top layer cross, complete the two simple cases of the same angle of the top surface, and complete the other five cases of the top surface color.

3. Then return to the four corner blocks of the third layer, restore the third layer of edge blocks, and it can be completed.

The third-order Rubik's Cube restoration process is as follows:

1. Make a white cross with a wheel.

2. The first layer of formulas: right shun, upper shun, right inverse, upper shun, right shun, upper shun, upper shun, right inverse.

3. The second layer of formulas: right only basic shun, upper shun, right shun, upper shun, right inverse, upper inverse, right inverse.

4. The second layer of formulas is reversed: right inverse, upward inverse, right inverse, upward inverse, right inverse, upward straight, right straight, right straight.

5. The third formula: right shun, upper shun, right reverse, upper shun, right shun, upper shun, upper shun, right inverse.

The official English name of the third-order Rubik's Cube is rubik'The S Cube, also named after Professor Rubik, was the most common type of Rubik's cube in the past. The third-order Rubik's Cube consists of a central axis connected to six central blocks, as well as 8 corner blocks and 12 edges, which, when connected together, form a whole, and either side can be rotated horizontally without affecting the other blocks.

The principle of the change number of the third-order Rubik's cube is as follows:

1. 8 corner blocks: The position can be swapped (8) and the direction can also be flipped (38), but a corner block (1 3) cannot be flipped alone, so there are 8 37 variations.

2. 12 edges: You can swap positions (12) and flip the direction (212), but you can't swap a pair of edges (1 2) alone, and you can't flip a edge (1 2) alone, so there are 12 212 (2 2) kinds of variations.

3. 6 central blocks: fixed and immovable.

Method steps

Step 1: Small white flowers (also known as the top shelf cross, the yellow center block is the stamen, and the four white edges are the petals).

Get a scrambled Rubik's Cube, first find the yellow center block, keep the yellow center block on top, and start to find four white edges in Sun Yin**, if you find a white edge is already in the white position in the above picture, this means that the edge has been completed, continue to find other unfinished edges.

Step 2: The bottom edge is returned to position (also known as the bottom cross, the process of correct restoration of the four edges at the bottom layer).

After completing the first step of the small white flower, continue to keep the yellow center block on it, take the Rubik's Cube, see what the color of the right center block of the Rubik's Cube is, then turn the yellow top layer, so that the color of the side of the white edge block is the same as the color of the right center block, as shown in the picture above, then turn the right hand twice, and the white edge will return to its final position correctly.

Continue to keep the yellow side facing up, turn the Rubik's Cube to the left as a whole, that is, the white edges that have just been completed are placed in the front position like banquet blocks, then look at the color of the center block on the right, repeat the above steps, and finally the four white edges return to the correct position one by one. This.

, the second step of the reduction of the four white edges is completed.

Step 3: Return to the bottom corner (restore the four corners of the first layer of the Rubik's Cube).

There are a total of eight corner blocks in the Rubik's Cube, first from the position of the top corner block to find the corner block with white color; Find a corner block with white and pronounce the other two colors of the corner block, for example, if you find a white, blue, and red corner block, you need to place the corner block between the blue center block and the red center block.
