Seriously, don't**don't**really bad to restore!! I don't know if the top surface of the landlord is completed, let's talk about the formula f (r u r' u') f'This is the formula f (r u r' u') f'This is the formula for the right-angled shape (the right-angled opening points to the palm of your right hand) The formula for the point shape is a combination of the above two formulas f (r u r' u') f'+f (r u r' u') f'or f (r u r' u') f' +f (r u r' u') f'The next step is to complete all the colors of the top surface, and use this formula (I call it the left and right hand formula) up and down and down [the right hand formula is rur in English'uruur'。The left-handed formula is l'u'lu'l'u'u'l] The specific formula is used in this way, the top surface of the Rubik's Cube is divided into 1--9 (horizontal), so when the position is not restored, use the left-handed formula; When there is no revert, use the right-handed formula.

If it is in other states, just twist it with the left-handed-hand formula, and finally it will twist out a figure that conforms to the left-handed-hand formula] The following is the diagonal formula for the top layer: x' r2 d2(r' u' r)d2(r' u r') === The four corners of the top surface are reduced First of all, the eye of this formula is facing the right (if you don't find the eye, you will definitely be able to find the eye by doing it again according to the formula), I still talk specifically about this company, generally I am yellow and white, first x'It is to put the whole Rubik's Cube along r'90 degrees (yellow becomes the front, white becomes the back), 180 degrees clockwise to the right of R2, and 180 degrees clockwise below D2, r'u'r 90 degrees counterclockwise on the right, 90 degrees counterclockwise on the top, 90 degrees clockwise on the right, 180 degrees clockwise below d2, r' u r'The right side is 90 degrees counterclockwise, the top is 90 degrees clockwise, and the right side is 90 degrees counterclockwise. The last step (so tired, finally to the last step), adjust the flute block If one side has been restored, put it behind, and see whether the remaining three flutes are clockwise or counterclockwise, clockwise first use the right-handed formula, and then use the left-handed formula.

Counterclockwise and vice versa. (When you use it, you have to look at the state, pay attention to changing directions, the left and right hand formula has been mentioned above) If there is no side that is restored, then use the right-hand formula first, and then use the left and right formula, at this time there must be one side that is restored. Continue with the formula above.

Need to follow the formula, the formula formula of the three-by-three-cube is as follows:

Clause. 1. Make a white cross.

Clause. Second, the first layer of formulas: right, up, right, up, right, right, up, up, right.

Clause. 3. The second layer of formulas: right order, upward order, right order, right order, right direction.

Clause. Fourth, the second layer of the formula is reversed: right inverse, upward inverse, right inverse, upward inverse, right inverse, upward order, right order, right order, right order.

Clause. Fifth, the third level of formula: right, up, right, up, right, right, up, up, right.

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!) can also flip the direction (38), but you can't flip a corner block alone (1 3), so you have 8!37 variations.

2. 12 edges: interchangeable positions (12!) can also flip the direction (212), but you can't swap a pair of edges (1 2) alone, and you can't flip a pair of edges (1 2) alone, so you have 12!

212 (2 2) variations.

3. 6 central blocks: fixed and immovable.

The solution of the Rubik's Cube is very simple and difficult, and it is simple that after mastering certain methods and skills, you will feel that it is very easy. Most of the Rubik's cubes on the market are six-sided four-by-four, and the technique of this Rubik's cube is also easy to master, and it is easy for beginners to use. So what are the skills of spelling the Rubik's Cube?

The skill of spelling the Rubik's Cube is to familiarize yourself with the formula, so that you can quickly spell the Rubik's Cube. Usually, you can put the red side of the ** block up, and then turn the Rubik's Cube to make the side blocks around the red turn red and turn into a red cross. Then restore the red corner of this side to this side, and first change the color of one side to red, the essence of this step is to change the color of one side to the same first.

After the first step, adjust the color of the top layer, turn it according to the formula, and turn the color of the top layer into a cross as well, just like in the first step, and then adjust the blocks of the same color around the cross.

The skills of spelling the Rubik's Cube are mainly to remember the formula, and the skill of playing the Rubik's Cube is the use of the layer-first method, taking the third-order Rubik's Cube skills as an example, which are the bottom cross, the bottom restoration, the inner restoration, the top cross, the top restoration, and the Rubik's Cube restoration, which can help people understand the use of the Rubik's Cube.

Points: Top Right, Up Left, Down Right, Up Left, Top Right, Up Left Left, Down Right.

Angle: Condition, the point is aligned with the upper right corner, up left, up right, top left, up left, top right, top right, bottom left.

Ridge: Condition, if you already know the first two layers, then you should be able to remember the condition. Bottom right, bottom right, top right, bottom left....Repeat until you recover.

Hehe, how to spell it out.

The top-level cross rotation method of the third-order Rubik's cube:

<>4. Set up a cross at the top, and adjust all the four top edges of the Rubik's Cube to the top surface with the same color as the top surface. At this point, there may be 4 situations: when we encounter a "point", it will be a "small turn" after the action, and then "one word", and finally a "cross".

In this way, the top cross of the third-order Rubik's Cube is turned out.

2. How to spell the third-order Rubik's Cube.

3. Second-order Rubik's Cube.

How to spell it. 4. Fourth-order Rubik's Cube.

How to spell it. 1.The third layer of the third-order Rubik's Cube should first turn out the top layer of the cross when fighting, and after turning it over, it should be rotated according to the formula of the lower right, upper right, front left, upper left, Sen Chi front right, and upper right, and the color of the top layer cross should be turned up after using the lower right, upper right, upper right, upper right, upper right, upward reversal of 180 degrees, and upper right reversal.

2.The formula is to flip 180 degrees to the right, 180 degrees down, 180 degrees to the right, right down, right down, right down, down 180, right down, right down, right down, the third according to the formula to return the top layer of the edges, the formula is to flip 180 degrees on the right, up left, right up, up left, right down, up right, up left, right down.

3.After being proficient, you can get out of the formula to rotate, the third-order Rubik's Cube is the most basic Rubik's Cube, just start learning to rotate by yourself, and use the formula to rotate the more complex steps, it should be noted that you can't use the formula at the beginning.

4.After the third-order Rubik's Cube is more proficient, you can learn the more difficult Rubik's Cube, and the high-level Rubik's Cube is also a down-order rotation when it rotates, and many rotation steps will use the rotation formula of the third-order Rubik's Cube.

5.The Rubik's Cube can train people's thinking and logical ability.

Especially children, play Rubik's Cube.

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!
