What is the formula after the third order Rubik s Cube is put together with the bottom cross?

After the bottom cross is erected, the bottom corner block can be restored first, or the bottom surface and the second layer can be directly restored. There are a lot of formulas. It is recommended to use the small station to take a look.

Get the bottom two rows on the sides right.

I have the formula here, please email me :wu

Third-order Rubik's CubeThe top-level cross formula is f(r u r'u'）f'。

This formula is used after the first two layers of the Rubik's Cube have been restored, and it is also the first step in the restoration of the top layer of the Rubik's Cube, which is relatively simple. In this step, you can ignore the color of the side of the top edge, and it will be adjusted later, as long as the cross pattern on the top surface is made, you can reduce the seven-step method of the third-order Rubik's Cube.

The formula is the top cross, the bottom edge homing, the bottom corner homing, the edge block homing, the top edge position, the top corner position, the top edge returning, the top corner returning, the seven-step reduction method is the most basic reduction method in the Rubik's Cube, according to the formula and steps can be quickly twisted.

Introduction to the contents of the third-order Rubik's Cube:

The Rubik's Cube is in Taiwan, China.

It's called a magic cube.

Hong Kong SAR, China.

It is called twisted dice, and in foreign countries it is called rubik's cube. by Hungary.

Invention of the 1974 Magic Cube by architecture professor and sculptor Ernor Rubick, the Ideal Toys company sold the toy in 1980 and changed its name to Rubik's cube。

The Rubik's Cube was the most popular in the 1980s. As of January 2009, more than 350 million Rubik's cubes have been sold worldwide. The third-order Rubik's Cube is a single world record.

It is the second held by China's Du Yusheng, and the average world record is held by China's Xu Ruihang.

After the 2nd floor is completed.

Turn out the top cross: down the right reverse, left up up.

Top flap: bottom, right, right, bottom, right, right, right.

Side (with the top face facing you): top right (right right), bottom left top (right right), bottom bottom.

The middle of the top side: upright, up, left, up, left, up, right, down, right, down, down, right, down, down, right, down, down, up, right, down, down, up, right, up, up

Each word is turned 90 degrees. Top: Turn up to the right layer.

Right: Turn right to the top floor. Down:

Turn down the right layer. Left: Turn left to the top floor.

Turn the front counterclockwise. (Right): Turn right to the bottom floor. ）

Bottom Right, Up Right, Front Left, Up Left, Front Right, Top Right, Down Right, Up Right, Top Right, Top Right, Up Right, Up Right, Top Right, Top Right.

The Rubik's Cube, also known as the Rubik Cube, is a mechanical educational toy invented by the Hungarian architecture professor and sculptor Rubic Airne in 1974.

The third-order Rubik's Cube has a total of 6 colors and 6 sides, and each side is divided into ** blocks, corner blocks and side blocks. Among them, there is only 1 surface of the ** block, and they are a fixed structure, so ** is a red block, so the other red colors must be concentrated on this face. And the red block is always opposite the orange block.

The edge block has 2 faces and 2 colors, and the corner block has 3 faces and 3 colors.

In the Rubik's Cube formula, each face is usually represented by a letter, and a letter will be used to indicate the layer or side to be rotated and the direction, for example: r (represents the right side turns 90 degrees clockwise), r (represents the right side turns 90 degrees counterclockwise), and r2 (represents the right side turns 90 degrees clockwise twice).

It should be noted that the name of each side is relative, for example, f is the front, which is the side facing you when you hold the Rubik's Cube, and if you rotate the imitation to the other side, then there is a new side to become the front.

The formula for the third layer of the Rubik's Cube cross is r'u'f'UFR, the Chinese character formula is the front right, the upper right, the upper left, the lower right, the upper right, the front left, the four edges of the top and middle layers.

The most used method is the seven-step reduction method when the third-order Rubik's cube is restored, and it is also the simplest, and the reduction steps are the top cross, the bottom edge homing, the bottom corner homing, the edge block homing, the top edge position, the top corner surface position, the top edge returning, and the top corner returning.

The formula for the seven-step reduction method of the third-order Rubik's Cube has 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, and r2d2r'u'rd2r'ur'，ru',l'u'lu2ru'r',u'l'ul。

These six letters represent the upper layer, the right layer, the front layer, the bottom layer, the left layer, and the back layer rotate 90 degrees in a clockwise direction, and the letter with an apostrophe is 90 degrees counterclockwise, and the back 2 is clockwise or 180 degrees counterclockwise.

After the third-order Rubik's Cube is proficient, you can also use the quick-twist formula, there is (rur'u'）（r'f）（r2u'r'u'）（rur'f'）、uz（u'rd'）（r2ur'u'r2u）z'（ru'）u’、（rur'f'）（rur'u'）（r'fr2u'r'u'）、r2u'r'u')(ruru)(ru'r)、(ruru2)(r'l'uru'l)(u2r2) for a quick restore.

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）（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、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, and there are many reduction methods for the high-level Rubik's cube, and there are many formulas for the high-level Rubik's cube, which is more complicated to remember.

The first step of the third-order Rubik's Cube cross is spelled as follows:

1. The first step is to spell the flower: take the white center as the bottom layer and the yellow center as the top layer. Move the white edges to the top yellow side. Make florets.

2. In the first case, the white edge is on the bottom white surface, and it is directly turned 180 degrees.

3. In the second case, the white edge is on the side of the middle layer, and you can push it directly to the top layer (it should be noted that if there is a white edge in the position of pushing up, you need to rotate the top layer to get rid of the white edge).

4. In the third case, the white edges are on the side of the bottom layer, the white edges are facing themselves, and the front is rotated 90 degrees clockwise to make the white edges in the middle layer, and then operate according to the second case.

5. In the fourth case, the white edge is on the side of the top layer, the white edge is facing itself, and the front side is rotated 90 degrees clockwise to make the white edge in the middle layer, and then operate according to the second case.

6. The second step is to turn the flower into a cross.

7. Rotate the top layer to make the white edge side and side center color the same, and then the side center block is facing itself, rotate 180 degrees clockwise, and the white edge changes from the top layer to the bottom layer. This is done until the cross is made.

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

1. The first step is to use white as the base: make the bottom cross. There is also the middle edge, the two colors must be the same, no matter what, you must be skilled in the cross, this is the foundation.

2. The second step is to restore the formula of the first layer: up, left, bottom, right. This formula is also a universal formula, as long as you move the corresponding color to the empty slot, use the formula to go up, left, bottom, right, and do it a few more times to restore the first layer.

3. The third step is to restore the second layer: there are two formulas for the second layer. Situation 1 formula: down, right, right, right, left, up, left, up! Situation 2 formula: up, left, up, left, up, right, down, right, down! These two formulas can restore the second layer.

5. The fifth step of the top surface is to restore the top surface, the formula: lower left left upper left lower left upper left, divided into one angle, two angles, three angles, all use this formula, do it several times to restore.

6. The sixth step is to return the top angles and restore the four top angles, and the formula is u' r d2 r' u r d2 r'2 。i means that the two floors on the left turn 90 down, and the one floor below d2 turns 180 to the right! It is also a few more turns of the top angle can be done.

7. The seventh step is to return to the top edge, that is, to restore the entire Rubik's Cube, the formula: lower left, lower right, lower right, lower left, upper left, upper left, use this formula to do two more times to restore!
