How to touch and restore the Rubik s Cube Primer, how to restore the Rubik s Cube

It's been a long time since I've spelled a Rubik's Cube, and today someone suddenly asked, so let's talk about it. (My best time is 1 minute 15 seconds).

The first layer: The first layer is self-taught, and it is very simple. Let's not talk about it.

The first layer and the first side are put together synchronously.

Second layer: Place the full side side down. Then align the middle of the second layer with the first layer to form a small inverted T-shape. Realign the middle of the third layer.

If the front is blue, the left is green, and the right is yellow. At this time.

The middle of the second and third layers is blue. The third layer is green above.

Use the left-shift formula: up-left-up+left+up+front+up-front-(up, down, left, right, front and back.) + refers to 90 degrees clockwise, - is the opposite, 2 fingers to 180 degrees).

If the front is blue, the left is green, and the right is yellow. At this time.

The middle of the second and third layers is blue. The third layer is yellow on top.

Use the right-shift formula: Up+Right+Up-Right-Up-Front-Up+Front+

When the second layer appears, the right side of the front is yellow. The second layer on the right and the left are blue with shortcut formulas.

Quick formula: Right + Up 2 Right - Up + Right + Up 2 Right - Up + Front - Up - Front + +

And so on, put the second layer together.

Third layer: After the second layer is put together. There will be 4 situations on the top surface (we will spell the word "ten" on the top surface next):

1.There is only one top color in the middle. Use the cross formula over and over again. Appearance 2

2.The top surface forms a top color. Turn the top face to turn the line into a vertical line. Use the cross formula again. Appearance 3

3.The top surface forms a right angle. One side up, the other side to the left. Use the cross formula again. Appearance 4

4.A "ten" word (needless to say in this case).

Cross formula: right-up-front-up+front+right+

Then the color. (The third layer is the same color as the side).

Color matching formula: right-up-right + up-right-top 2 right + top 2 Effect: The color of the top layer on the left remains unchanged. The remaining three sides of the middle color rotate counterclockwise.

until the color is the same in the middle of the four sides.

After the top cross is put together. Here are three formulas to spell out the top surface:

1.Left + Right - Up - Right + Up + Left - Up - Right - Up + Right + Effect: The top right corner of the top surface does not move. The lower right corner flips to the top of the upper left corner, the upper left corner flips back to the bottom left corner, and the lower left corner pans to the lower right corner.

2.Front + Right - Front + Left 2 Front - Right + Front + Left 2 Front 2 Effect: The top right corner of the top surface does not move. The rest of the triangles are translated counterclockwise for one round.

3.Left + Right + Up 2 Left - Right - Back + Front + Up 2 Back - Front - Effect: It's hard to say, just use it once after the six sides are good (this is also a shortcut formula).

My record is 45 seconds, but I also learned it online, a**, called "Rubik's Cube Paradise", there is a beginner tutorial, it will be slower at the beginning, and slowly the formula is familiar, and the speed is raised, the formula is very complete, there are pictures and **. (I'm really not advertising, it's really good, maybe I'm used to it differently!) ）

To enter the main text, the first side does not use a formula, but the side must form a line, and the next is to put the second layer of edges.

Only the letters are clockwise, the letters with ' after the letters are counterclockwise, the numbers 2 are twisted 2 times, U is up, D is down, L is left, R is right, F is front).

1 Takeaway: Place the edge on the top layer on the right. The middle destination of the prism is placed on the right rear.

rurur)(u'r'u'r')

2 Points: Place the edges on the top layer on the right. The middle destination that the prism will reach is placed in the front right.

r'u'r'u'r' )(urur)

Step 3: Cross on the top surface.

1 Key points: 1. First of all, recognize the state of the top color.

2. Correctly distinguish between points, folds, and lines.

3. From the point to the fold, from the fold to the line, from the line to the cross.

2 Key points: 1. First of all, recognize the state of the top color.

2. Correctly distinguish between points, folds, and lines.

3. From the point to the fold, from the fold to the line, from the line to the cross.

Step 4: Flip the top corners.

1 Key points: 1. The corner blocks that need to be flipped are counterclockwise.

2. The corner blocks that don't need to be flipped are adjusted to the right rear corner.

r u'u' r' u' r u' r'

2 Key points: 1. The corner blocks that need to be flipped are clockwise.

2. The corner blocks that do not need to be flipped are adjusted to the left front corner.

rur'u)(ru'u'r')

Step 5: Order of the four corners of the top surface.

1 Key points: 1. Find the two corner blocks on the side of the top layer that are the same color. If you find more than one of these faces, you prove that the corner block is right, and you put this face on the right.

r2d2 (r'u'r)d2 (r'ur')

2 Key points: 1. Find the two corner blocks on the side of the top layer that are the same color. If you find more than one of these faces, you prove that the corner block is right, and you put this face on the right.

2. If you can't find one such face, then do the formula on any surface according to the formula in the angle position 1, and 1 will appear.

r2d2 (r'u'r)d2 (r'ur')

Step 6: The order of the top edges.

1 Points: 1. The correct side is placed at the back. The triangular change is counterclockwise.

r u' r)(u r u r)(u' r' u' r2)

2 Key points: 1. The correct side is placed at the back. The triangular is reversed clockwise.

r2' u)(r u r' u')(r' u')(r' u r')

If you don't have the right face, just make a formula).

After that, it was restored, and if you have any questions, please ask us.

The restoration method is described below

First, the yellow one in the middle is facing up, and make a yellow cross at the top, which is the other color blocks to the corresponding position. Then return the yellow corners to the middle edge block, and adjust the yellow corner block around the cross, so that the yellow side is misaligned. Position the yellow blocks at the four corners according to the formula, and finally adjust the color blocks on the edges to the corresponding positions, and you're done.

The Rubik's Cube, also known as the Rubik Cube, was first invented in 1974 by Professor Ernor Rubick of the Budapest School of Architecture in Hungary.

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" respectively.

and "counterclockwise": the complete surface completed in the first step has always been used as the bottom surface, and the face facing itself is the "front", and the lower two layers of the four sides are complete, which refers to the restoration of the lower two layers of the four sides (as shown in the figure below), and the formula is: the moving square is the middle block of the upper layer of the side, and according to the color of the side, judge whether it moves to the left or right side of the middle layer of the 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 color of each side of the four corners of the top layer in the state of the four corners of the sixth step (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, each pair of upper corners, is to use a "plus" and then complete the next corner).

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

Preparation tool: a Rubik's cube.

1. First put the white block in the middle on the top of Wang Dan, and then make a white cross at the top, that is, the blocks of other colors are in the corresponding position (see the diagram, pay attention to the formula marked above, and do it correctly).

2. Then the white corner blocks are put in place (it is very complicated, but it is easier to understand by looking at the picture).

3. Then let the middle layer edge block return to position. 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 layer (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 of the Rubik's Cube to the cross, which is a bit difficult, and look at the formula prompts.

6. Usually at this time, the yellow block and the color of the side will be misaligned, according to the mantra (I haven't eaten it thoroughly) the yellow block at the four corners will be trapped in the Zen disturbance position.

7. Finally, adjust the color blocks on the side to the corresponding position, and the whole Rubik's Cube is completed.

The Rubik's Cube is a little trick to restore

1. Learn the basic formula: Familiarity with the basic Rubik's Cube formula is the basis for the reduction of the Rubik's Cube. Learn how to rotate the faces and layers in the Rubik's cube and memorize common formulas such as top-level reduction, middle-level reduction, bottom-layer reduction, etc.

2. Step-by-step method: Rubik's Cube reduction is broken down into multiple steps to solve, and each step focuses on solving a specific problem. For example, restore the first layer, then the second layer, and finally the top layer.

3. Visual memory: Try to use visual memory to remember the state and rotation of the Rubik's Cube. By practicing repeatedly, memorizing the various sides and the position of the blocks of the Rubik's Cube will help you find the right turning steps faster.

4. Pattern recognition: learn to observe and recognize patterns on the Rubik's Cube. During the restoration process, you will find that some specific patterns are repeated, and learning to identify these patterns and corresponding solutions can improve the speed and accuracy of the restoration.

5. Look for optimization methods: Once you are able to complete the restoration of the Rubik's Cube, you can further explore more advanced restoration methods. Learning more complex formulas or algorithms can make your restoration process faster and more efficient.

6. Practice and patience: Rubik's Cube restoration requires a lot of practice and patience. Don't be discouraged, practice more, and gradually increase the speed and skill of the restoration.

Summary. The Rubik's Cube can be restored according to the formula, and the reduction formula is as follows: the first step is to make a white cross; Step 2, the first layer of formula:

Right Shun, Shang Shun, Right Reverse, Shang Shun, Right Shun, Shang Shun, Shang Shun, Right Reverse; The third step and the second formula: right order, upper order, right order, right order, right order, right reversal, right reversal, right reversal, right reversal; The fourth step, the second layer of the formula is reversed: right inverse, upward inverse, right inverse, upward inverse, right inverse, upward straight, right straight, right straight; Step 5, Level 3 Formula:

Specific links. Rubik's cube, jujube skin, also known as rubic cubes, was first invented in 1974 by Professor Erno Rubick of the Budapest School of Architecture, Hungary. The Rubik's Cube has a variety of ways to play, such as racing, blind twisting, and single twisting, and its popularity has endured, and it is one of the most popular intellectual jokes and jokes that are held every year. In the usual sense, the Rubik's Cube refers to the third-order Rubik's Cube in the narrow sense.

The third-order Rubik's Cube shape is usually a cube and is made of elastic hard plastic. The regular racing game is to disrupt the Rubik's Cube and then restore it in the shortest possible time. In a broad sense, the magic touch rock beam square refers to all kinds of geometry that can be disrupted and restored by rotation.

The Rubik's Cube, along with Huarong Dao and the single aristocracy of France (independent diamond chess), is known as the three incredible minds in the intellectual game world.
