The Rubik s Cube Quick Restore only twists 20 times, and the Quick Rubik s Cube Restoration Tutorial

The method of the Rubik's Cube to quickly restore only 20 twists:

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 blocks of other colors are in the corresponding position (small complex, see the diagram, pay attention to the formula marked above, do it correctly).

2. Then return the white corner blocks to their positions.

3. Then let the middle side block return to position, turn the white side downward, find the red and green edge 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 1 situation on the figure, and rotate the Rubik's Cube according to the formula to make the side blocks return to position.

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.

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.

5. The next step is to adjust the yellow corner blocks of the Rubik's Cube around the cross, which is a bit difficult here.

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.

7. Finally, adjust the color block on the edge to the corresponding position, and you're done.

Hello, what you said is the least step to restore the Rubik's Cube, through some fixed algorithms, and the primary gameplay is fundamentally different, it is recommended that beginners learn the primary gameplay first, and learn other restoration methods again.

The method of the Rubik's Cube to quickly restore only 20 twists:1. Hold the white block in the middle against the top.

2. Make a white cross at the top, that is, the blocks of other colors are in the corresponding position, and then return the white corner blocks to their positions.

3. Then let the middle side block return to position, turn the white side downward, find the red and green edge blocks, if the red and green edge blocks are on the top layer, then rotate the top layer in the clockwise direction.

4. Then turn the Rubik's Cube according to the formula to make the side blocks return to their positions.

5. If the red and green edge blocks are in the middle layer, but the position is wrong or the color is wrong, you can first make the red and green edge blocks in the front right position.

6. Then follow one of the following orders again, rotate once to restore.

。。。Unless you mess it up and revert back to it, there's no such thing.

1 First, face the white square from the middle to the top.

2 Make a white cross at the top, i.e. bring all the other colored squares to their respective positions, and then put the white corner blocks back in their positions.

3 Then put the middle side block in the right place, turn the white side block over, and find the red and green side blocks. If the red and green edge blocks are on the top layer, then rotate the top layer clockwise.

4. Turn the Rubik's Cube according to the formula of the Rubik's Cube to return the edge of the cube to its original position.

5 If the red and green edges are in the middle of a layer, but the position or color is incorrect, you can put the red and green edges on the front to the right.

6. Re-rotate in one of the following order and resume once.

Hello, about the Rubik's Cube 20 times to restore the minimum number of steps in the WCA competition project, you need to give the minimum number of rotation steps that are disrupted by the Rubik's Cube.

Only 20 twists, that depends on fate.

Quick Rubik's Cube Recovery Tutorial 10 seconds:

The first step is cross, and there is no formula for this step.

The second step is f2l, and the formula is fruru) (rfr), (rfru) (r urf), ruru) (rurur), (ruru) (ruuru) (rur), (ruru) y(rurf2), y(ruru) (rur), (ruru) (rur), (ruru) (rur), (ruru) (rur), etc.

The third step is OLL, and the formula is (fruruf) (fruruf), f(ru ru)yx(rf)(ruru)f,(ruu)(rurur),(ruu)(r2frf)u2(rfrf),f(ruru)fuf(ruru)f,r(r2uru)(ruru)(rr), etc.

The fourth step is PLL, and the formula is (ruu) (ru2) (rbru) (rurbr2u), (ru ru) yx2(rurur2)xz(rurur), r2urur) (uru)(r2bub), etc.

The basic formula for restoring the Rubik's Cube in 10 seconds is (r uuru)2 y(rur), (u r uru)y(ru r). The process of Rubik's Cube restoration is divided into many different situations, and the formula corresponding to each situation is different, there are four steps, and the formula for each step is also different.

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 by looking at the merger map).

3 Then let the middle edge block be homed. Turn the white side downward, find the red and green edge 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 on the diagram, and then 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 is wrong or the color is wrong, first make the red crack green edge block in the right front position, and then rotate it 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 blocks around the cross, which is a bit difficult, just look at the formula.

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

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

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

2.When the top cross is restored, we will take the cherry blossom in the middle block and correspond to the cross to restore.

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

4.After the first layer is restored, we carry out the restoration of the second layer, and the second layer of edges is to remove lead and return to position, that is, the steps of restoring the four edges in the middle layer of the Rubik's Cube.

5.After the second layer is restored, we carry out the "fish" construction of the top layer, and first spell out the shape of the fish (or the shape of the cross) on the top of the last layer that has not been restored.

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

7.We return the top edge to the other side of the four top edges of the cube so that the color of the other side of the four top edges of the cube is the same color as the other four sides where it is located.

8.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.

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

Tools Ingredients: Rubik's Cube.

1. First of all, you need to understand the meaning of some letters of the Rubik's Cube, R represents the right, L represents the left, F represents the front, B represents the back, D represents the bottom layer, and U represents the top layer. At the beginning, you need to build a cross, which is the shape of ten, and there will be some situations that can be solved by the method in the figure.

2. Then restore the four corner blocks, generally the following three situations will be encountered, according to the method in the figure. Restoring the second layer, we will encounter two situations: one left and one right. Then to build the top cross, here you just need to remember a formula:

f r r' u' f', depending on the situation, do it a few times, and you can build the top cross.

3. Then go to the top level of restoration, a total of seven situations, this is to be written down. Then adjust the order of the top layer corner blocks, if it goes well, you will encounter these four situations, and you can complete the Rubik's Cube by restoring it according to the formula. In special cases, if you do not encounter these four situations in the sixth step, you need to follow the steps in the figure to forcibly adjust the Rubik's Cube to the above four situations.

In this way, the Rubik's Cube is restored.

Introduction to the Rubik's Cube:

Rubik's Cube (English: rubik'S Cube, formerly known as Magic Cube, known as Magic Cube in Taiwan and Twist Dice in Hong Kong, is a mechanical educational toy invented by Hungarian architecture professor and sculptor Ern Rubik in 1974, known as the Rubik Rubik's Cube.

Since its invention, more than 100 million Rubik's cubes have been sold worldwide. The Rubik's Cube and China's Huarong Qinzhi and France's single aristocracy (independent diamond chess) are known as the three most incredible in the world of intellectual games.

In addition, in addition to the third-order Rubik's Cube, there are second-order, fourth-order to ten-type nine-order, and there are more and more new Rubik's cubes invented in modern times, and they are not the same shapes, but they are all interesting.

When one side of a large cube rotates horizontally, the single color of each adjacent side is destroyed, and a new pattern cube is formed, and then it is rotated and changed again, forming that each side is made up of small squares of different colors. According to expert estimates, all possible pattern compositions of the third-order Rubik's Cube are about. The gameplay is to rotate the scrambled cube through six sides to restore it to six sides into a single color as soon as possible.

The Rubik's Cube tutorial Ming Chunmeng 24 steps are restored as follows:

1. Simply put together a shuffled Rubik's cube into a flower of the same color;

2. Rotate the cross flower to make it a cross of the same color, and the center point is consistent with the side color when rotating;

3. Then put it together into one side, so that it is the same as the color of the center color block into a T-shape, the top of the bridge layer is the same color, and the four sides are T-shaped;

4. Spell the second layer to make it the same color as the bottom layer;

5. The top surface is also put together into a cross, and there are a few more of the same color on the side of the cross;

6. Complete the top surface color turning, so that the top surface color is unified, and the top side color is not left alone;

7. Adjust the position of each color block and turn it to the correct position.

1. Rubik's Cube

Rubik'scube) in a narrow sense, refers to the third-order Rubik's cube. The third-order Rubik's Cube shape is usually a cube and is made of elastic hard plastic. The racing game is to break the Rubik's cube and then restore it in the shortest possible time.

As of December 2018, the official world record for the restoration of the third-order Rubik's Cube was broken by China's Du Yusheng in Wuhu, a single second.

Second, the structure of the Rubik's Cube

1. Senna center block (6 pieces).

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.

2. Edges (12).

The surface of the rib block is two squares, similar to a cuboid protruding from one side of the cube, which allows the edge 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.

3. Corner blocks (8 pieces).

The surface of the corner block is three squares, and the structure resembles a small cube protruding from one side of the cube, so that the corner block can 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.

4. Central shaft (1):

The support shaft needed to support the block and rotate the block.
