Rubik's cube tutorial FL, someone knows, tell me.

The solution of the Rubik's Cube is very complicated, so it is impossible to explain it clearly here, and it is meaningless to say a specific solution to the solution process.

So I want to give you a hint. In the Rubik's Cube, it is not based on human faces. In other words, it seems that a face can't be put together, and one side is red, even if it is successful. But in units of blocks, each block has its specific position and direction. As long as one orientation is wrong, this block is wrong. And as long as it is put right, even if the surface looks irregular, 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 set the top surface to big red, the surface facing you to yellow, and the left surface to white. Then, the center block above should be red, the center block opposite you is yellow, and the center block on the left is white. After positioning, you can start.

Start with the top two contact blocks, such as the middle block of the layer where the red surface and the yellow surface are in contact, the top should be red and the bottom should be yellow, then place the top three contact blocks, such as the red, yellow and white blocks, and try to put them in the right position, then place the middle two blocks, and finally place the bottom two blocks and the bottom three blocks. Note that sometimes the set blocks will be temporarily disrupted because the following blocks will be placed, which is for sure.

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!

Explanation: All 20 rotatable squares on the Rubik's Cube can form 43,000,000,000,000,000,000,000,000,000,000,000,000 (4,300

Megabytes). This is probably the most obvious difficulty in solving the puzzle. Optimality 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 first of these 20 rotatable squares 12 is located one by one, so most of the time, you

You only need to consider the position of a square.

However, as long as only so few combinations of squares are considered at a time, it is entirely possible to write them down and send them to everyone.

This situation provides a suitable rotation method. Therefore, no matter which combination, 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.

Put it in the wrong place)

Marks and terminology

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 plane (choose your favorite color)

Front: Front plane

Left: left plane

Right: right plane

Bottom: bottom plane

Backplane: Backplane-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 plane, choose

After determination, it should remain unchanged in the whole solution process. Please note that the colors of the right, left, back and front planes are up to you.

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

Rubik's cube in hand). 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). In any rotation group, the colors of the right, left, back and front planes also remain different.

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 solution does not require rotating the back.)

Clockwise and counterclockwise are based on each face.

On the right front is an edge box, which is at the edge position between the front plane and the right plane at a specific time. Right front top

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 blocks involved are represented by the above terms. 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 is consistent with 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 mixed with red, blue and

When the corner of the green central square is in the correct 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 this solution are summarized as follows:

1. Choose one of the six colors you like, and then use this color to give the plane of the center square.

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 below 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 that the squares be temporarily removed from their correct positions, and then

Go back to the original position in the right direction.

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

Introduce a complete and clear solution. After reading the following introduction, it may destroy you 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. It's easy.

Task, you may be willing to do the work 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.

first step

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

Before solving, select the color of the top surface. Don't forget that the color of any plane is determined by the color of its central square.

It's decided. 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 squares belonging to the four edge positions of the top plane. These four top squares

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 of the squares are in the right place, then you just need to put these five steps.

(1A- 1e) Do it two or three times. If you are still confused 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 hold the whole thing in 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 this top. This square that requires a solution is called an on-demand square.

1C: If this box is already on 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. According to this.

You need to do one of the following 1 1 group rotations at the position of the square. For example, the current position of the desired box is the upper right part.

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

Rotation method from top right to top front: right-front-

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

Rotation method from top left to top front: left+front+

Front right to front top rotation method: front-

Rotation method from right rear to front top: right 2- right front 2.

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

Front Left to Front Up Rotation Method: Front+

From bottom to front: the first two

Rotation method from bottom right to top front: 2 from bottom to top.

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 front top box is currently in the correct position but in the wrong direction, please rotate it in the following directions:

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

(These four top squares are oriented one by one, so you may need to do these five squares 1A- 1e four times.

Steps. After this step, a cross pattern will appear on the top plane (if you choose green as the top color).

A green cross will appear).

Second step

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.

Square positioning and position orientation. In this series of rotations, the top edge box will be temporarily moved, but this will be appropriate.

repair

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

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

That's enough for four times

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

Box). This is an on-demand box. If this jukebox is currently in the right position, but in the wrong direction.

, please refer to 2E.

2B: If the requested box is now on the top surface, please make the following set of rotations. Please hold the Rubik's Cube in a certain direction to make it necessary.

Party violation is at the top right.

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

This rotation moves the required block to the bottom plane.

2C: Rotate the bottom plane so that the desired square currently on the bottom plane is weighed to the corner of the top surface it should occupy.

Just below the site (this site is called the on-demand site). 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 right front to right front 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 right top.

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.

Please, everyone.

Third step

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 an "intermediate link"

Layer plane ". Once this step is completed, two-thirds of the Rubik's Cube will be completed. Because each should belong to the middle edge.

The following four steps (3A-3D) should be taken for the edge position of the box. You may find a middle border box again.

It's already in the right place.

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

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

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

The box is in the front right.

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

3C: At this time, the required square has reached the bottom plane. Rotate the bottom plane so that the colors of the vertical plane and the four sides of the required square are the same.

(back and forth, left and right). Then hold the Rubik's cube correctly and 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 lower right to the right front. If the required square

The block is located in the front plane and rotates in groups from the bottom to the right front.

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

Right rotation method from bottom front to front: (bottom-right side-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.

.

Front-right directional rotation method (step *** 15): (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 box (it was originally located in

The square at the top right has moved from its correct position to one position more than once. If you hand over one of them.

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

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 that, try again from 3A.

Fourth step

Step 4: Corner of the bottom surface (lower left front, lower right front, rear left and rear right)

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, rotate the bottom surface so that as many corners as possible are in place, regardless of its direction for the time being (temporarily

Regardless of the edge squares on the bottom plane). At least two, sometimes even all, can be made by turning the bottom surface.

The four corners of the bottom plane are in the correct position. If there are still two squares in the wrong position, then their positions are just so.

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

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 hold 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+) down 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 hold the Rubik's cube correctly, so that the two squares to be adjusted are in these two positions.

Settings):

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

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

Normal rotation.

-There is only one rotation step in this step, but it should be used repeatedly. Just make sure to hold the lever correctly before each rotation.

Law.

-grip (this is the key):

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

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 patches at the same time:

-A: Two pieces are adjacent: put two pieces on the right front and right rear of the top respectively.

-B: Two pieces are opposite: put two pieces on the right front and left rear of the coat respectively.

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

The edge of two standard color blocks, set this edge to the left.

Hold the Rubik's Cube tightly and you can start turning:

(right+top+right-) top+(right+top2right-) (it's as simple as that, only this set of rotations)

If after a set of rotations, if the relative directions of the four squares are wrong (this rotation will not change their relative positions, but just the same)

The finished two floors are a little staggered, so don't pay attention to them for the first time. Then we will redefine the grip and continue to rotate repeatedly until we reach four corners.

The relative direction of the block is correct (usually 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

Top edge (front bottom, left bottom, back bottom and right bottom)

Look at the position of the bottom edge:

-If none of the edge boxes is in the right direction, proceed as per the method of 5A.

-If only one edge frame 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-right+front+) (left+right-down 2) (left-right+front+) (left+right-)

After the rotation, look at the bottom surface before deciding 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. Then do 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.

The square on the right is adjacent: make a square on the right in front of the bottom. (not shown)

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