What are the rules of the Rubik's Cube? What are the rules of the Rubik's Cube?

There is a formula for playing Rubik's cube. Let me tell you about it.

In the Rubik's cube, it is not based on faces, that is to say, one side looks like it can't be put together, and the other side is red, even if it is successful. On the contrary, it is based on blocks, and each block has its specific position and placement direction. As long as one direction is wrong, this piece will not be placed correctly. As long as you put it right, even if it looks irregular on the surface, it is half the battle.

Let's give an example. First you have to set the center of the Rubik's cube. For example, you should set the top to big red, the face facing you to yellow and the left to white. Then, the center block at the top should be big red, the center block opposite you is yellow, and the center block on the left is white. After positioning, you can start.

First, put the contact blocks on the upper two sides, such as the middle block of the layer where the red surface and the yellow surface contact, then put the upper three contact blocks, such as the red, yellow and white blocks, straighten them as much as possible, then put the middle two blocks, and finally put the lower two blocks and the lower three blocks. Note that sometimes the set blocks will be temporarily disrupted by placing the following blocks, which is certain.

I didn't make it clear. I'm sorry, you can read it carefully several times, and you can definitely solve the Rubik's cube! ?

Solution: All 20 rotatable squares on the Rubik's Cube can form 43,000,000,000,000,000,000,000,000 (43,000?

Millions of megabytes). This is probably the most obvious difficulty in solving the puzzle. What are the advantages of this solution?

The point is that it tries to make you only need to consider no more than 30 squares involved in this step at any time in the 5 steps?

Combination mode. The front 12 of these 20 rotatable squares are positioned one by one, so many times, you?

You only need to consider the position of a square.

Even if only so few combinations of squares are considered at a time, it is entirely possible to write them down and give them to everyone.

This situation provides a suitable rotation method. So, no matter which combination you start with, no matter whether the Rubik's Cube is twisted or not.

No matter how chaotic it is, this solution can guarantee success. Note: If you have disassembled the Rubik's Cube, please make sure it is not assembled?

Is it misplaced?

Signs and terms?

The standard names of the six planes of the Rubik's Cube used in the whole process of solving the Rubik's Cube are as follows:

Top: Top surface (choose your favorite color)?

Front: Front plane?

Left: Left plane?

Right: right plane?

Bottom: bottom plane?

Back: back plane-and less used?

The color of a plane depends on the color of its central square (which cannot be rotated). You can choose the color of the top surface, choose?

After solidification, it should remain unchanged throughout the dissolution process. Note that the colors of the right, left, back and front planes depend on you.

How to take the Rubik's cube can be different. So the front plane can be one of any four colors (by turning you?

Once the front plane is determined, the colors of the right, back and left planes and the color of the bottom plane remain unchanged.

After choosing your favorite color). Do you keep the colors of the right, left, back and front planes in any set of rotations?

Change, but in the next set of rotation, its color often changes.

Right+: Rotate the right plane 90 degrees clockwise.

Right-:Rotate the right plane counterclockwise by 90 degrees.

Right 2: Rotate the right plane by 180 degrees (the clockwise and counterclockwise effects are the same at this time).

Front+: Rotate the front plane 90 degrees clockwise.

Front-:Rotate the front plane 90 degrees counterclockwise.

Front 2: Rotate the front plane by 180 degrees.

Left+: Rotate the left plane 90 degrees clockwise.

Left-:Rotate the left plane counterclockwise by 90 degrees.

Left 2: Rotate the left plane by 180 degrees.

Bottom+: Rotate the bottom plane 90 degrees clockwise.

Bottom-:Rotate the bottom plane 90 degrees counterclockwise.

Bottom 2: Rotate the bottom plane by 180 degrees.

Top+: Rotate the top plane 90 degrees clockwise.

Top-:Rotate the top plane 90 degrees clockwise.

Top 2: Rotate the top plane by 180 degrees.

This scheme does not need to be turned over?

Clockwise and counterclockwise take each face as the clock face as the standard.

On the right front is an edge box, which is at the edge position between the front plane and the right plane in a specific time. Upper right front?

It is a corner box, which is in the angular position between the front plane, the right plane and the top plane at a specific time.

Therefore, 12 square is: bottom front, bottom left, bottom back, bottom right, front left, front right, front top, left back, left top,?

Right back, back top and right top. The eight corners are: left lower front, right lower front, left lower rear, right lower rear, left upper front and right front.

Top, left rear top and right rear top. Any rotation and the square involved are represented by the above terms. Do you want to use this article?

To solve this problem, you must hold the Rubik's Cube in a certain direction, so that the squares to be moved are consistent with those described in this article.

If you don't understand, please look at the muscles.

When the color of a square matches the color of its side or corner position, we call it position.

Right or placed correctly. When the colors of all sides of a square are consistent with the colors of the central square of its adjacent plane, I?

We call it the right direction. For example, a corner box painted with red, blue and green, when it is adjacent to red, blue and green?

When the corner of the green central square is in the right position, but only when its red, blue and green sides are different?

When it is consistent with the red, blue and green central squares, it can be considered that the orientation of this square is correct (the direction and position are correct).

The five steps in the solution are summarized as follows:?

1. Choose one of the six colors you like, and then give the plane where the central square of this color lies?

Orientation and direction of four right-angled sides (i.e. top side).

2. Locate and orient the four corner boxes on the selected top plane (i.e. the top corner).

3. Locate and orient the four edge squares of the layer under the top plane (i.e. the middle edge).

Locate and orient all the 1 2 blocks in steps1to 3 one by one. So far, two of the three points have been completed.

The square of. ?

4. Locate and orient the four corner boxes on the bottom plane (i.e. the bottom corner).

5. Locate and orient the four edge squares on the bottom plane (i.e. the bottom edge).

Each big step is generally divided into two small steps.

-1 Locate these squares one by one.

-2 Determine the direction of these squares one by one. This requires moving these squares from the correct position for a while, and then what?

Go back to the original position in the right direction.

- 1 - 2 - - 3 - ?

- ?

- 4 - ?

Last chance: If you like, you can try to solve the Rubik's Cube by yourself just by relying on the above instructions.

Introduce a complete and clear solution. Reading the following introduction may destroy your ability to open it yourself with the above enlightenment.

The fun of solving the Rubik's cube. In addition, the first two steps only introduce the method of completing a plane. Is it easy?

Task, you may be willing to do it yourself (or you have already finished it). The first key step is step 3?

. ?

Step one, step two, step three, step four and step five?

Step one?

Step 1: Top edge (front top, left top, back top, right top)?

Select the color of the fixed top surface before solving. Don't forget that the color of any plane is determined by the color of its central square.

Yes Hold the Rubik's Cube correctly, so that the plane you choose faces upwards. This is the top surface, which has been completely solved?

Keep the plane unchanged during the process.

The purpose of this step is to locate and orient the four edge squares belonging to the top plane. These four top squares?

Are placed and oriented one by one. You should do the following five steps for each square (1A- 1e). If you're lucky?

If you are lucky, maybe one or two squares are in the right place. So, you just need to put these five steps?

(1A- 1e) Just do it two or three times. If you still have questions about this, please check the contents of the standards and terms.

1A: Hold the Rubik's Cube correctly so that there are no placed and oriented squares at the top of the front. You might want to transfer the whole cube into your hand?

The Rubik's cube should do this, so that it will also change the color of the front plane.

1B: Find the square that should belong to the top. A square that requires a solution is called an on-demand square.

1C: If this square is already at the top, but the direction is wrong, please refer to1e.

1D: there are 1 1 possibilities for the position of this required square, so there are 1 1 groups of corresponding rotations here.

Just do one of the following 1 1 group rotations at the box position. For example, the current position of the box is the upper right position.

Then it can be handled according to the rotation from the right top to the front top.

Right upper to front upper rotation method: right front-?

Back top to front top rotation method: top+right-top-front-?

Top left to top front rotation method: left+front+?

Front right to front top rotation method: front-?

Back right to front top rotation method: right 2 front right 2?

Left back to front top rotation method: left 2 front+left 2?

Front left to front top rotation method: front+?

From bottom to front: top 2?

Spinning method from bottom right to top front: bottom-top 2?

Bottom back to front top rotation method: bottom 2 front 2?

Rotation method from bottom left to top front: bottom+top 2?

1E: If the current position of the front top box is correct, but the direction is wrong, please rotate it in the following directions:?

Directional rotation method of front roof: front roof+left roof-

The four top squares are oriented one by one, so you may need to repeat these five squares 1A- 1e four times?

One step. Once this step is completed, a cross pattern will appear on the top plane (if you choose green as the top color?

There will be a green cross.

Step two?

Step 2 vertex angle (left front top, right front top, left rear top, right rear top)?

The purpose of this step is to give four corners belonging to the top surface, while keeping the top edge of the placement square.

Location and orientation of the box. In this series of rotations, the top edge box will be temporarily moved, but all will be appropriate?

Reduced. ?

The following six steps (2A-2F) are required for each of the four squares belonging to the angular position of the top surface. Similar?

If you are lucky enough to come across a corner box that is already in the right position, then you don't have to do it?

That's four times.

2A: Find a vertex box that is not correctly positioned and oriented (that is, should any one belong to the vertex position?

This is an on-demand box. What if this jukebox is currently in the right position, but in the wrong direction?

, please refer to 2E.

2B: If the demand cube is now at the top, please make the following set of rotations. Please hold the Rubik's cube in a certain direction to make it demand?

Party violation is at the top right.

Right front from top to bottom front left rotation method: left-down-right+?

This rotation moves the required cube to the bottom plane.

2C: Rotate the bottom plane so as to weigh the desired square currently on the bottom plane to the top angle it should occupy?

Just below the required part (this part is called the required part). Hold the Rubik's cube in a certain direction, so that the required part is the upper right of the front?

At this time, the required position is the right front top position. At this time, the required square should be in the correct position on the bottom surface.

2D: To correctly place the required corner box, please do the following rotation.

Bottom front right to front right top rotation method: right-down-right+?

2E: If the front top box is in the wrong direction, do one of the following two sets of rotation (note: only do one set).

Directional rotation method of front, upper and right: lower right, 2 right+,front+lower 2 front-?

Directional rotation method of front, upper right and lower right: front+lower 2 front-,right-lower 2 right+?

2F: If the direction of the box in the upper right corner is still incorrect, repeat the rotation you made in 2E. This will make the front upper right frame?

The direction and position of the block are correct.

You may need to repeat these six steps (2A-2F) four times to complete the positioning and orientation of these four corner boxes?

After doing this, one third of the entire Rubik's cube, that is, all the squares on the top surface, will be in the right direction?

Everyone. ?

Step three?

Step 3 middle edge (left front, right front, left rear, right rear)?

The purpose of this step is to locate and orient the four edge boxes below the top plane. This step can be regarded as a "middle".

Solution of "layer plane" Once this step is completed, two-thirds of the Rubik's Cube will be completed. Should each one belong to the middle edge?

For the edge box, the following four steps (3A-3D) are performed. You may find another box in the middle edge?

It's already in the right place.

3A: Find a middle-level edge box whose orientation has not been determined (that is, a box that should belong to the middle-level edge position)?

This is the demand box. If the location of this demand box is correct, but the direction is wrong, please refer to 3D.

3B: If the required cube is not on the bottom plane, please make the following set of rotations. Hold the Rubik's cube in a certain direction correctly, and that's right?

The square is on the right front.

Front right to bottom plane (bottom back) rotation method: right-bottom+right+bottom+front+bottom-front-?

3C: At this time, the required square has reached the bottom plane. Turn the bottom plane to make the colors of the vertical plane and four sides of the required square?

(front, back, left, right). And then hold the Rubik's cube correctly to make it necessary?

The position is the right front position. If the required square is on the right plane at this time, make a set of rotations from the bottom right to the front right. What if the required square?

The block is located in the front plane and performs a set of rotations from the bottom to the front right.

Rotation method from bottom right to front right: (bottom+front+bottom-) front-(bottom-right-bottom+) right+?

Rotation method from bottom front to front right: (bottom-right-bottom+)+(bottom+front+bottom-) front-?

3D: Hold the Rubik's Cube in a certain direction, so that the required Rubik's Cube is in the right front position. If the direction is wrong, do the following set of directional rotations?

. ?

Right front directional rotation method (*** 15 step): (right-down+right+) (down+front+down-) front-(down+right-down+)?

Right+(down+front+down-) front-?

Right and wrong methods:?

This set of rotations is longer than the previous two steps. In the whole process of this series of rotations, there is only one vertex square (located in the original?

The square on the upper right) has moved from its correct position to a position more than once. Suppose you hand in one of the groups?

If you make a mistake or get confused, stop immediately and try to restore the top plane. Usually, you have to turn around?

The plane or right plane restores the box to the top surface, and then, in step 2, several sets of rotations are redone to restore the wrong vertex angle.

Stop. After this operation, try again from 3A.

Step four?

Step 4 Bottom angle (lower left front, lower right front, lower left rear, lower right rear)?

This step is to locate and orient the four corners on the first plane. This is done by positioning first and then orienting. This time?

The four squares are not placed separately, but are completed as a group at one time. Do it again according to the following instructions about 4A-4F?

You can complete a step.

4A: First, it is necessary to rotate the bottom surface so that as many corners as possible are in place, regardless of its direction (temporarily?

Regardless of the edge squares on the bottom plane). You can make at least two, sometimes even all, just by flipping the bottom?

The four corners of the bottom plane are positioned correctly. If there are two squares left in the wrong position, then their positions are nothing more than?

On two adjacent or two opposite corners. For the former, 4b can be rotated; For the latter, 4C rotation can be done.

4B: If two wrong positions are adjacent, the next set of rotations can make them switch positions.

Rotation method for adjusting the left front of the bottom and the right front of the bottom (pay attention to correctly holding the Rubik's cube so that the two squares to be adjusted are in these two positions?

Set): (right-down-right+) (front+down+front-) (right-first+right+) next 2?

4C: If two misaligned corners are opposite, the next set of rotations can adjust them.

Bottom front left, bottom back right (pay attention to correctly hold the Rubik's cube so that the two squares to be adjusted are in these two positions?

Set):？

(Right-Down-Right+) (Front+Down 2 Front-) (Right-Down+Right+) Down+?

4D: At this point, the boxes in the four bottom corners have been properly placed. At this time, if the directions of the four bottom corner boxes are incorrect, please press the following?

Normal rotation.

-There is only one rotation step in this step, but it should be used repeatedly. Just ensure a correct grip before each rotation?

Law. ?

-grip (this is the key):

Put the layer to be adjusted on top (the whole process). Take the color of the center of the top surface as the standard color. Observation?

Are there standard color blocks at the four corners of the top surface?

-There is only one standard color: put this on the top, front and left.

There are two standard color blocks at the same time:?

-a: Two pieces are adjacent: put the two pieces at the top, front, right and top, back and right positions respectively.

-B: Two pieces are opposite: put the two pieces in the front, back, left and right positions.

None: Look at the standard color blocks on the side (only look at the eight color blocks on the four corners) and find that they appear at the same time?

Which side of the two standard color blocks is set as the left side.

Take the Rubik's cube and you can start turning:

(right+top+right-) top+(right+top 2 right-) (it's that simple, just rotate this group)?

If after a group of rotations, if the relative directions of the four squares are wrong (this rotation will not change their relative positions, but will only be the same?

The finished two floors are a little staggered, so don't worry about it for the time being), then re-determine the grip and continue to rotate repeatedly until all four corners are square?

Until the relative orientation of the block is correct (usually repeated 3-5 times). Adjust the top layer so that the color of its corner box is the same as the finished two?

The layer is consistent, remember to reset this layer to the bottom.

Step five?

Step 5 Top edge (front bottom, left bottom, back bottom and right bottom)?

Look at the position of the bottom edge:?

-If none of the edge squares are in the right direction, follow the 5A rotation method.

-If only one edge box has the correct direction: follow the rotation method of 5B.

-There are two correct borders in the right direction: do it according to the 5C rotation method.

5A: Do the following set of rotations, this time just keep the top and bottom surfaces unchanged.

(left and right+front+) (left+right-down 2) (left and right+front+) (left+right-)?

Look at the bottom surface after rotation and then decide the next rotation mode.

5B: Hold the Rubik's Cube correctly, so that the edge with the correct position or direction is in the position in front of the bottom. What about group 5A?

Turn around. After turning, look at the bottom and decide the next turning method.

5C: Hold the Rubik's Cube to:

The relative position of a- square: make a square at the position before and after the bottom.

B- Adjacent positions of correct squares: Make correct squares in front of the bottom (not shown) and on the right?

Transfer mode: (left+right+front) (left+right-down-) (left+front-) (left+right-down-) (left-?

Right+up 2) (left+right-)?

The formula is more troublesome. Let's talk about the basic principle first: put the Rubik's cube: observe the upper left and front, and the sideline is Y-shaped. General idea: 1. Spell the cross above. 2. Put the upper four corners (note that the color on the edge intersecting the upper edge is the same) on the edge T-shape. 3. Turn the Rubik's Cube upside down. For the four corners of the middle layer (the middle layer and the lower layer are finished), 4. For the top surface (original bottom surface) of the upper layer, 5. For the upper formula, it is good to apply it to the online search repeatedly. It's quite simple to say, but it's quite troublesome. I won't repeat it. I should be able to achieve the first few steps by myself. When I do the next step, I will make sure to complete this step and not destroy the achievements of the previous step.

Rubik's cube has no rules, but there are companies. Details are as follows:

1, to learn the Rubik's cube, we must first understand its upper structure, and know that the corner block can only be transposed with the corner block, the side block can only be transposed with the side block, and the center block cannot be moved.

The standard colors of the International Rubik's Cube are: upper yellow-lower white, front blue-rear green, left orange-right red.

2, front f, back b, left l, right r, up u, down d.

3, the meaning of the formula, the second picture, the average beginner does not need to remember.

4, complete a layer

(1) Complete the first crossing.

The first case is shown in the figure: the formula is R2.

The second situation is as shown in the figure:

The color below white is orange, and the color is specially turned out for easy observation.

The formula is d'? What? r？ f？ (See Step 3 for the specific transmission method)

Other circumstances.

The positions of the orange and white blocks are correct, but the colors are reversed. I will first change R2 into the second case, and then use the formula to restore the second case!

Other circumstances.

In both cases, the right front stop should be moved to the upper and rear positions. Shall we do R first? D'? Move to the front and bottom position, and then do R? "Restore orange and white", and then move D2 to a lower position. The above two situations are transformed into the above first and second situations respectively. Its symmetry is also restored according to the above similar ideas! If the orange and white blocks are wrong at first, move to the position of the lower back!

(2) Complete the corner block of the first floor.

Or put the cross on the top floor. When restoring the corner block, we first look for the corner we want to restore at the bottom, and then look for it at the top!

? Case 1 :D formula milk powder

Case 2 Formula: R' D' R

However, the following situations may also occur:

White at the bottom! We call this situation invisibility. What we need to do when restoring is to make its white color visible, at the same time, at the bottom!

Do you want to do R 'first? The corner is in the lower right corner, and white is visible. Then do D or D2 to move to the lower left or front left, and then do R to restore white orange! Then move that corner to the front, below and to the right, which is the second situation above!

In the end, there are two situations, that is, the position of the corner block is right, but the color is wrong.

Situation 1:

Do you want to do R 'first? d？ r？ Change it to the first case, and then use the formula of the first case.

Situation 2: Do R first? D'? r？ D enters the second situation!

5. Complete the second floor.

Then we began to restore the second floor. First, we turn the Rubik's Cube upside down, that is, put the first layer at the bottom.

6. There are only two situations to restore the second floor.

Scene 1: You are yours, you are yours, you are mine, you are mine.

Note: y is to turn the whole Rubik's cube in the first picture to the right. Become figure 2.

The second case: R' U' R' U' R' U R U RU

7. In other cases, the location is correct but the color is wrong, or it is already on the second floor but the location is wrong.

Let's "restore" a square randomly from the top to the front right (with or without yellow edges! ), the blue block and the red block will naturally move to the top floor (replaced), and then turn to the top floor appropriately, and one of the two situations introduced in the second step will appear.

8. Complete the top floor

(1) top cross

After completing the second layer, the top layer will have the following three situations:

For the above three situations, we only need to remember one formula:

Formula mumumum' um' um' UU

Our ultimate goal is to make the top surface like this.

If the top of your Rubik's Cube is already like this, then this step can be skipped directly, but it is not always so lucky, and the formula still needs to be memorized. The following are the first three states and screwing methods.

Black in the top view indicates yellow blocks.

(2) Top plane

The first formula (left-handed formula): L'U'LU'L' U2L

The second formula (right-handed formula): RUR'URU2R'

Seven situations encountered after twisting the top layer of the Rubik's cube into a cross

(3) Top corner block

After the color of the top layer of the Rubik's Cube was unified, we began to restore the positions of the corners of the Rubik's Cube. First, turn the top layer of the Rubik's cube to find two corner blocks with correct positions. Place the side with two corner blocks near the palm of your right hand, and then turn the Rubik's cube with the following formula to restore the corner blocks to the correct positions.

Formula R2F2R'B'RF2R'BR'

If there are no two right corner blocks, we can turn the top of the Rubik's cube over, put the two right corner blocks on the diagonal, then find any side and twist the formula above to get the two right corner blocks on one side.

(4) Top edge block

1. Make the left-handed formula first, turn the Rubik's cube, and then make the right-handed formula.

2. Make the right-hand formula first, turn the Rubik's cube, and then make the left-hand formula.

3. In these two situations, first find any side to make the left-hand (right-hand) formula, then turn the Rubik's cube to make the right-hand (left-hand) formula, and you can get the above situation, and then restore it.

The Rubik's Cube has been completely restored!
