The Rubik's Cube, also known as the Rubik Cube, is called the Magic Cube, and in Taiwan, it is called the Magic Cube.

In Hong Kong, it is known as Rubik's cube。Third-order Rubik's Cube.

It is a 6-sided cube made of elastic hard plastic.

The core is an axis and consists of 26 small cubes. There are 6 of them, including the center square, which are fixed and only one side is colored. There are 8 corner squares (3 colored sides) that can be rotated. 12 edge squares (edges) (2 colored sides) can also be rotated.

The Rubik's Cube cross is followed by one or two layers.

Summary. Step 1: The yellow center is up, you grab the top layer with one hand, first face one of the white "petals" facing us, then turn the bottom two layers, align the color of the white petals with the center of the Rubik's cube, and then turn the white petal 180 degrees and flip it to the bottom.

Step 2: Repeat this by aligning the four petals one by one with the center of the sides and turning 180 degrees to the bottom layer. Remember! All four petals must be aligned with the center to turn 180 degrees to the bottom. No one is missing!

Step 3: Flip the white side over and you will be able to see a white cross, and check if the white cross is aligned with the four sides, if they are all aligned, you have succeeded.

I would like to ask, is there a formula?

Ask about custom messages].

The mantra of the Rubik's Cube cross is: Lower Right, Upper Right, Front Left, Upper Left, Upper Right, Lower Right, Upper Right, Upper Right, Upper Right.

I would like to ask, what does the front left mean?

Corresponds to your front.

What about the bottom right? Ask about custom messages].

The last mantra is to dial back the top layer with the left index finger on the top right, and dial back the top layer with the index finger of the right hand on the top right (abbreviated as the right hand dial at the back), okay, thank you.

The easiest way to put together 6 sides of the Rubik's Cube is to follow the formula:

The first step is to make a white cross;

The second step, the first layer of formulas: right order, up order, right inverse, up order, right order, up order, up order, right inverse;

The third step and the second formula: right order, upper order, right order, right order, right order, right reversal, right reversal, right reversal, right reversal;

The fourth step, the second layer of the formula is reversed: right inverse, upward inverse, right inverse, upward inverse, right inverse, upward straight, right straight, right straight;

The fifth step and the third level formula: right order, up order, right inverse, up order, right order, right order, up order, right order.

The origin of the Rubik's Cube:

Rubik Erno, a Hungarian professor of architecture and sculpture, made the first prototype of the Rubik's Cube inspired by the sand of the Danube to help his students understand the composition and structure of the cube of space.

In 1974, Professor Rubik invented the first Rubik's cube and in 1975 he was granted 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 tenons, not easily separated by external forces, and can be made of 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.

1. Find the yellow center block, the center block is a surface block.

4. Because the white edge is two sides, that is, there are two colors. Colors other than white, which may be blue, green, red, orange, find the central block of the same color.

7. When all four edges are rotated to the face centered on the white center block, the cross is ready.

Notes:

The history of the development of the Rubik's Cube:

Chinese milestones of the Rubik's Cube:

On October 1, the Guangzhou Open was held in Nanwu Middle School in Guangzhou, which was the first professional Rubik's Cube event in China, and all the results were recognized by the WCA. It indicates that China's Rubik's Cube competition is moving towards regularization and beginning to be in line with international Rubik's Cube competitions.

The Beijing Summer Rubik's Cube Open is the most important milestone for China's Rubik's Cube to the world. An astonishing lineup of more than 150 participants gathered the most complete Rubik's Cube masters in China's history, 14 national records, 2 Asian records, and 5 world records were born in this competition. The Party School of the Ministry of Railways, where the competition was held, has also become a place that that generation will never forget.

Rubik's cube spells all six sides, first spell one side (this is very easy), and then divide it into three layers layer by layer, you can have six sides! (Convention: For example, the bottom left below, is the leftmost column that turns 90 degrees downward, that is, 90 degrees in one's direction).

1. The first layer: full side, the first layer of transposition points: 1 pair of diagonal for 2 adjacent angles for 3 pairs of intermediate for 4 neighbor for interposition.

2. The second layer: align the downward reversal (take the switch left as an example).

Lower left, lower left, upper left, lower left, front left, lower left, front right, right (change right, push).

3. Final Steps:

1 The bottom of the "ten" character: left and right, right down, up, right, front, left, left, front, right, right (repeated).

2 Four diagonal sides of the bottom surface: to change the two sons to the right: upper right, upper left, upper left, lower right, upper right, lower left, upper left, upper left, upper right, upper right, lower right, upper right.

3 The bottom is complete: the upper left corner is excellent (put the one with the same color as the bottom surface in the upper left corner, if this one is not on the bottom surface, put it on the side, if the bottom surface has it, press it on the bottom surface and put it on the bottom surface to put the Rubik's Cube) lower right upper right upper right upper left * 2 (upper left turn 180 degrees) upper right (repeatedly, that is, start from the upper left corner and do it again, if the bottom is not complete).

4 Change the third layer (this one is easy), all six sides!

If you are interested, you can take a look! As long as it is used flexibly, it can also be singled out and put on two sides. Among them, I feel that the 1st and 3rd of the three are the most wonderful!

In fact, the above is a general method, and it has been proven that a Rubik's cube in any state can always be put together in a maximum of 26 moves!

How to spell the Rubik's Cube cross is as follows:

The Rubik's Cube is a fun and challenging toy, and in the Rubik's Cube, the Rubik's Cube cross is the first step in the primary solution. Spelling the Rubik's Cube Cross requires certain techniques and skills, and below I will introduce in detail how to spell the Rubik's Cube Cross.

Step 1: Find a colored front and put it in front.

First of all, put the color in the Rubik's Cube on the top surface to complete the side, and use this colored surface as the front. Of course, this front can be changed to a different color, but the formula may change for each subsequent step.

Step 2: Find the center block and rotate it

The second step is to identify the center block of a particular color and align it to the side of that color. Then rotate the cube so that the center block is the same as the cross.

Step 3: Balance the side edges

Next, you need to find the edge blocks on the same side that are adjacent to the center block. The colors don't need to match, just the position must be correct, then select the sides that balance the edges, transferring the two pieces to the top surface.

Step 4: Rotate the Rubik's Cube to match the upper and lower blocks

In the fourth step, you need to rotate the top face until it matches the blocks of the upper and lower parts. This means that, in addition to the bottom surface, you have to look for the four side blocks at the corners and the rest of the sides, and move those blocks to the appropriate positions.

Step 5: Turn over

The fifth step is to turn down the front of the entire Rubik's Cube so that it is aligned with the bottom. At this point, the bottom surface becomes the top of the Rubik's Cube, and the robot view goes down. When you do this, your front will also become the back.

Step 6: H-shaped

In the sixth step, you need to find the edge blocks that match the color first. Then use the formula fururf, which can produce an H-shape. If the arrow in the corner is pointing forward, the formula only needs to be changed: fruruf to complete the H-shaped assembly.

Step 7: Spell the cross

The seventh step is to spell out a cross by manually rotating the top of the Rubik's Cube. In this step, you rotate the top face until you generate a criss-cross shape.

Once you've completed all of the above steps, you're ready to assemble the Rubik's Cube cross. Of course, these steps are just solving the cross in the Rubik's Cube, and completely cracking a Rubik's Cube is very complex and requires more algorithms, skills, and mental preparation. It is recommended that novices try to start by solving the Rubik's Cube Cross to gradually improve their skills and level.

The formula for the Rubik's Cube cross is (rur'）、f'u'f), that is, the Rubik's Cube is rotated out of the top layer of the cross, which can also be restored according to the color of the center block and corner block.

The cross on the top layer is the first step of the seven-step reduction method of the third-order Rubik's Cube, the first thing is to rotate the cross on the top layer, and then you can restore it according to the steps of the seven-step reduction method.

When the top cross is restored, first find the yellow center block, the yellow center block is facing up, and then find the position of the four white edges, if the white edge is in the left hand position, there is no white cross on the left side of the yellow side, the left hand will turn the Rubik's Cube up once, turn the white edge to the yellow side, in the right hand position, there is no white petal on the right side of the yellow side, then turn the right hand upwards until a white petal appears on the yellow side.

The formula for the seven-step reduction method of the third-order Rubik's cube is r'uf'u'、r'd'rdx,3or5,rur',(rur'u'),rur'u')3,u'l'ulufu'f',uru'r'u'f'uf,f(rur'u')f'，(rur'u'2 and (rur'u')5,r2d2r'u'rd2r'ur'，ru',l'u'lu2ru'r',u'l'ul。

After turning the Rubik's Cube out of the top cross, the four corners of the Rubik's Cube should be restored, and the formula for the return of the edges in the Rubik's Cube is (u'f'UF) (grip uru'r'), the formula used for the restoration of the four edges in the middle layer is (uru'r'）（u'f'uf) and then use f(rur'u'）f'Resets the color of the center block and the top layer.

Next is the formula r for the return of the top angle'u2rur'ur, object vertical u'ru'u'r'u'ru'r, and finally with r'u2rur'ur、u'ru'u'r'u'ru'r Returning the apex to its position is complete.

The third-order Rubik's cube is the easiest to restore according to the seven-step reduction method, there are many restoration methods for the high-level Rubik's cube, and there are many formulas for the high-level Rubik's cube.
