Is there any way to restore the Rubik s Cube, and how to restore the Rubik s Cube

Idea: The process of restoring the Rubik's Cube is as follows: first restore the first layer, including the bottom surface and the four sides near the bottom surface, and the next thing to do is to complete the second layer:

To the center, to the prism around the center The third layer: to the top cross, to the side cross, to the top, to the four corners u: above d:

Below r: right l: left f:

Front B: Back R2: Right 180 degrees clockwise Individual letters e.g

r is 90 degrees clockwise on the right r' is 90 degrees counterclockwise on the right. See.

The first layer, no formulas, solve it yourself. The second layer has two steps: 1) For the center, it is easy to match with the restored first layer 2) For the center edge, you can operate according to the formula shown in the figure:

Generally, the third layer is the top cross, the right cross (the overall view is the side cross is all good), the top surface, the four corners Formula four: (r u r' u'）f' ' u2 r u r' u r b' r f2 r' b r f2 r2 4.（r u' r）（u r u r）（u' r' u'r2) The formula you have to do is 3 for the top surface and 4 for the four corners.

As a Rubik's Cube enthusiast, there are many ways to restore the Rubik's Cube, but I will share a trick with a beginner today, it only takes seven steps to restore the Rubik's Cube, let's take a look at my ultimate!

If we want to restore the Rubik's Cube, we must first understand its structure

1.The Rubik's Cube has a total of 6 colors and 6 sides, and each side is divided into ** blocks (6 blocks in the middle), corner blocks (8 blocks in 4 corners) and side blocks (12 blocks in the middle of 4 sides).

2.For the sake of description, the following rotation operations are replaced with letters. The key letter plus a float represents counterclockwise, and the letter rotates clockwise by default. Use letters to indicate the 1 layer or 1 side to be turned, and the direction.

3.For example: r (for right 90 degrees clockwise), r (90 degrees counterclockwise for right), r2 (90 degrees clockwise for right).

4.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, if you rotate the imitation to the other side, then there is a new side to become the front.

Let's use the next 7 steps to restore the Rubik's Cube!

1.First, the side with the white block in the middle (the one with the rubiks logo) is facing the top, and then make a white cross at the top, that is, the blocks of other colors are in the corresponding position (small complex, see the diagram, pay attention to the mantra marked above, do it correctly).

2 Then the white corner blocks are put in place (the cheats are very complicated, or it is easier to understand the picture when the manuscript is clear).

3 Then let the middle edge block be homed. Turn the white side downward, find the red and green side blocks, if the red and green edge blocks are on the top layer, then rotate the top layer in a clockwise direction until the side blocks are the same as the one in the diagram, and then turn the Rubik's Cube according to the formula to make the side blocks return to their positions. If the red and green edge blocks are in the middle layer, but the position or color is wrong, first make the red and green edge blocks in the front right position, and then rotate them again in one of the following orders.

4 Then adjust the top (which should be yellow) side block upwards to make a yellow cross. If the yellow cross does not appear on the top layer after 1 rotation of the formula, you can repeat the rotation until the yellow cross appears.

5 Then adjust the yellow corner block to the cross, which is a bit difficult, look at the mantra prompt.

6 Usually at this time, the yellow block and the color of the side will be misaligned, according to the mantra (I haven't read it yet) to position the yellow block at the four corners.

7. Finally, adjust the color blocks on the edge to the corresponding position. Succeed with flying colors!! Get excited.

In summary, the Rubik's Cube will get bored if it all depends on memorizing formulas and spelling hand speed.

I teach my children to play with the Rubik's Cube, and I only teach these 7 basic formulas, and I don't teach other formulas that can be converted from these few basic formulas. Although the child has more steps and takes longer to operate, he can use his brain more.

After we get the Rubik's Cube, the first step is to build the underlying cross, when building, we can randomly choose to restore, and at the same time, there is no formula, we can only rely on ourselves to restore.

When the top cross is restored, we do the middle block and the cross correspondence to restore.

After that, we do the bottom corner grouping, and the first layer is restored.

After the first layer is restored, we carry out the restoration of the second layer, and the second layer of edges is returned, that is, the steps of restoring the four edges in the middle layer of the Rubik's cube.

After the restoration of the second layer, we carry out the "fish" structure of the top layer, and the top of the last layer that has not been restored will first spell the shape of the fish (or the shape of the cross).

When the fish or cross is spelled out, we do the top layer restoration, and the top layer is restored.

After that, we return the top edge to the top of the cube so that the other side of the four top edges of the cube is the same color as the other four sides of the cube.

Finally, we perform the apex corner homing, that is, the other two sides of the four vertex corners of the Rubik's cube that have been placed are also the same color as the corresponding faces. In this way, we will restore the entire Rubik's Cube, and the Rubik's Cube will be restored.

Method 1: White Cross First, you can first place a color facing up, then find the center block, and put the four side blocks adjacent to it to face them up on the same side to form a white cross. Then, place the four corner blocks where they should appear.

Finally, you only need to turn the four side blocks to the center block of the corresponding color, and you can complete the restoration of the Rubik's Cube.

Method 2: Fridrich MethodThe Fridrich method is a relatively advanced Rubik's Cube restoration method, which requires mastering certain formulas and skills, but can greatly shorten the recovery time of the Rubik's Cube. There are two formulas used in this method:

F2L and Yes are the first two layers, and this formula can help you restore the first two layers at once. Ol stands for orientation of last layer, and this formula can help you find the correct position of the last layer. It takes a bit of practice and skill to use this method, but it can greatly speed up your recovery, so if you're interested, you can learn on your own.

The above are two ways to quickly restore the Rubik's Cube, for beginners, it is easier to master the first method, and the restoration of the Rubik's Cube can be completed in a short time. Hope it helps!

First of all, one side should be restored, then one layer should be restored, and then one layer should be restored. Secondly, the second layer is restored, the Rubik's Cube is flipped, the top layer is restored, the last circle is restored, and the six sides of the Rubik's Cube are restored.

The specific steps are as follows:

Step 1: Put the white block in the middle on the top side, make a white cross at the top, that is, the other color blocks are in the corresponding position, and then return the white corner block to the position.

Step 2: Return the middle edge block to the top edge block and adjust the top edge block upwards to make a yellow cross.

Step 3: Adjust the yellow corner blocks around the cross, usually at this time, the color of the yellow block and the side will be misaligned.

Step 4: Finally, adjust the color block on the edge to the corresponding position.

Notes:

The restoration of the Rubik's Cube needs to be carried out layer by layer, and it cannot be done in one step, and it requires patience and care in the restoration process to completely restore the Rubik's Cube.

The Rubik's Cube is restored by the traditional reduction method.

1. First put the white block in the middle on the top side, and then make a white cross at the top, that is, the other color blocks are in the corresponding position of the crack and cautious return. (as shown in the image below).

2. Then return the white corner blocks, then let the middle edge blocks return to position, turn the white side downward, and find the red and green edge blocks. (as shown in the image below).

3. If the red and green edge blocks are on the top layer, then rotate the top layer in a clockwise direction until the side blocks are the same as the one on the figure, and rotate the Rubik's Cube according to the formula to make the side blocks return to their positions. If the red and green edge blocks are in the middle layer, but the position or color is wrong, you can first make the red and green edge blocks in the front right position, and then rotate them again in one of the following orders. (as shown in the image below).

4. Then adjust the top layer (should be yellow) side block upwards to make a yellow cross. If there is no yellow cross on the top layer after turning the mantra once, you can repeat the rotation according to the mantra until the yellow cross appears. (as shown in the image below).

5. The next step is to adjust the yellow filial piety corner of the Rubik's Cube to the cross, which is a bit difficult here. (as shown in the image below).

6. Usually at this time, the yellow block and the color of the side will be misaligned, and the yellow block at the four corners will be positioned according to the formula. (as shown in the image below).

7. Finally, adjust the color block on the edge to the corresponding position, and you're done. (as shown in the image below).

Here's how to restore the Rubik's Cube:

1. Find a random color first, and directly restore it to a complete surface.

2. Four-sided bottom layer and center block restoration: take the complete surface of the first step of restoration as the base, restore the trapezoidal shape formed by the bottom layer and the center block of the four sides (as shown in the figure below) while the second step is completed, the side of the first step is still intact, there is no formula for these two steps, so if you want to complete the Rubik's Cube restoration, the above two steps are the most basic, and this needs to be explored and practiced by yourself.

3. The "plus" and "subtraction" in the Rubik's Cube formula refer to "clockwise" and "counterclockwise" respectively: the complete surface completed in the first step has been used as the bottom surface, and the face facing itself is the "front", and the four sides are complete under the two layers, which refers to the complete restoration of the lower two layers of the four sides (as shown in the figure below), and the formula is: the moving block is the middle block of the upper layer of the side, and according to the color of the side, it is judged whether to move to the left side of the middle layer or move to the right side:

Middle left square subtract up, subtract left, add up, add left, add up, add up, add up, subtract up, subtract before; The center and right squares are added up, right, subtracted, subtracted, subtracted, subtracted, subtracted, added, added.

4. Restore the top layer of the cross: After completing the third step, the next step is to restore the top layer of the cross (as shown in the figure below), the specific formula is: front plus, right plus, top plus, right subtraction, top subtraction, front subtraction.

5. The square block on the top layer of the four sides (cross homing): the square in the top layer of the four sides, that is to say, the square in the middle of the top layer of the four sides corresponds to the center block of the middle layer (as shown in the figure below), the formula is: first of all, the condition is to find the only side of the four sides that can be opposed, and this side is the "front", and the others are not faced.

If there are two sides that can be matched, use the following formula once, and you can achieve the conditions for using the formula: right plus, plus up, right subtract, add up, add right, add 180 degrees, right subtract.

6. The alignment of the squares on both sides of the top layer of the four sides (the corners of the upper layer are aligned): the squares on the top two sides of the four sides are aligned, which refers to the alignment of the squares at the upper corners of the four sides, and the homing does not mean that the color should be aligned, as long as the color of this piece corresponds to the color of the three sides, as shown in the figure below. The mantra is:

First of all, the condition is to find a counterpoint angle and put it on the top right of the top layer of the "front" surface, if you can't find the counterpoint, you can use a formula, you can see the counterpoint: add up, add right, subtract up, subtract left, add up, subtract right, subtract up, add left.

7. The completion of the top layer refers to the completion of the matching of the colors of each side of the four corners in the sixth step in the state of returning the four corners of the top layer (as shown in the figure below), the formula is: right subtraction, bottom subtraction, right addition, bottom addition, right subtraction, left subtraction, right addition, bottom addition (repeatedly use this formula, sell a pair of upper corners, that is, use a "upper plus" and then complete the next corner).

The method of restoring the Rubik's Cube is as follows: turn out and turn out a cross at will, front right homecoming, front left homecoming, top cross homecoming, top layer homecoming, top corner homecoming, top layer restoration.

The various types of blocks of the Rubik's Cube cannot be moved to each other, and the corner blocks cannot be moved to the position of the edge or center block, and the same is true for the edge and center block. In addition, none of the 26 blocks have the same color for two blocks, each of which is different. We restore the Rubik's Cube by restoring each "block" to its own position.

Moreover, the six central blocks can only be rotated, not moved, so only twelve edges and eight corners need to be restored.

1. Turn out and turn out a cross at will.

2. Front and right homing (up, right, up, right, up, forward, up, forward), front and left homing (up, left, up,

3. Top cross homing: right bottom up, left front up, left front up, left front up and right up (1-4 times).

4. Top level homing: bottom, left, right (2 or 4 times), upper right bottom, left and right, right and right (2 or 4 times).

5. Top angle homing: 180° upper right and lower right upper and lower right and upper right and 180° right.

6. Top-level restoration: 180° from right to right, right to right, left to right.

Structure of the Rubik's Cube:

Center block (6): The center block is connected to the central axis, but can be rotated freely in the direction of the axis. The central block has a square surface and a slightly cuboid structure, but the inner side of the cuboid is not flat, and there is a cylinder in the center that connects to the central axis.

Viewed from the side, there will be an arc-shaped groove on the inside of the center block, and when combined, the grooves on the center block and the side block can form a circle. As you rotate, edge and corner blocks slide along the grooves.

Edges (12): The surface of the edges is two squares, similar to a cuboid protruding from one side of the cube, which allows the edges to be embedded between the two central blocks. The radian on the surface of the box is the same as the arc on the center block and can be slid along.

The inside of the cube has a notched corner, and when combined, the grooves on the central block and the edges form a circle. As you rotate, edges and corners slide along the grooves. In addition, this notched corner is also used to fix the corner block.

Corner Blocks (8): The surface of the corner block is three squares, and the structure resembles a small cube protruding from one side of the cube, which allows the corner block to be embedded between the three edges. Like the edges, the surface of the small cube has the same curvature, allowing the corners to rotate along the grooves.

Center Axis (1): The support axis required to support and rotate the block.
