How to restore the Rubik s Cube, how to restore the Rubik s Cube?

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

Preparation materials: ordinary third-order Rubik's Cube.

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

2. Pay attention to the relative color of the flower, if white is the center point, use the yellow opposite the white to make the petals.

3. Rotate the cross flower.

Make it a cross of the same color.

4. Note that the center point is the same color as the side when turning.

5. Then put it together to make it the same as the color of the central color block into a T-shape.

6. The top layer is the same color, and the four sides are T-shaped.

7. Spell the second layer so that it is the same color as the bottom layer.

8. The top surface is also put together into a cross.

9. Of course, there are many crosses with a few more colors on them.

10. Complete the top surface color turning and shouting potatoes, so that the top surface color is unified, and the top side color is not left alone.

11. Adjust the position of each color block, and turn the hidden line to the correct position.

According to the following 7 steps to roll the socks, you can return the plaintiff Yu Hao Moqing digging prescription:

The shuffled Rubik's Cube reduction needs to rely on formula formulas, which are as follows:

The first step is to make a white cross.

The second step and the first layer of formulas: right order, right order, right order, right order, right order, right order, up order, right order.

The third step and the second level of formulas: right straight, up, right, up, right, right, up, right

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.

The fifth step and the third level formula: right order, up order, right inverse, up order, right order, right order, up order, right order.

The principle of the change number of the third-order Rubik's cube is as follows:

1. 8 corner blocks: You can swap positions and flip directions, but you can't flip a corner block alone, so there are 8 37 variations.

2. 12 edges: You can swap positions and flip directions, but you can't swap a pair of edges alone, and you can't flip a pair of edges alone, so there are 12 212 2 2 2) variations.

3. 6 central blocks: fixed and immovable.

The reduction method of the third-order Rubik's cube.

When it comes to the Rubik's Cube, many people think that it is an intellectual game played by children and school students. In fact, it is a public lifting base letter educational toys, people of any age can play, especially the elderly, play a Rubik's Cube, to improve memory, enhance attention, exercise hand and brain flexibility, coordination, are good.

The Rubik's Cube is a mechanical educational toy invented in 1974 by architecture professor Rubic Erno. It was loved by the public in the 80s. According to statistics, 20% of the world's population was playing the Rubik's Cube at that time, and this popularity is surprising.

Nowadays, there are many types of Rubik's cubes, from entry-level Rubik's cubes to advanced professional Rubik's cubes. The Rubik's Cube introduced here today refers to the most basic and common standard third-order Rubik's Cube.

Playing the Rubik's Cube is to turn 9 stickers on 6 sides into the same color, which tests the ability to observe, remember, and practice.

The method of recording the rotation of the Rubik's Cube, known as the Simmaster marker, has now become a universal standard, popularly known as the "Rubik's Cube Formula Symbol".

The reset mark consists of two parts: "each layer code" and "rotation direction".

Each layer is referred to by an initial. r(right), l (left), u(up), d(down), f(front), and b(back) refer to the right, left, top (top), bottom (bottom), front (front), and back (back) layers, respectively.

Rotation direction marking: rotate 90° clockwise, and write the code of each layer directly; Rotate 90° counterclockwise, and suffix [in the code of each layer'] or [i]; In each layer code suffix or, the default clockwise rotation is 180°.

There are many ways to reduce the third-order Rubik's Cube, among which the "layer-first method" is the most suitable method for beginners to master.

A third-order Rubik's Cube, "from top to bottom" can be understood as "top", "middle", and "bottom".

In the process of restoration, due to the different placements, personal habits, etc., the formulas used according to the markers are different.

The following is a reduction method that I have compiled based on the teaching of multiple teachers and according to my own preferences.

Step 1: Create a white cross on the underside.

1. Establish a white cross on the bottom surface.

Step 2: Return the underside white to its position.

Step 3: Middle layer homing.

Step 4: Yellow cross on the top layer.

Step 5: Restore the top yellow surface.

Step 6: The top corner block is in place.

Step 7: The top edge is homebound.

To twist the Rubik's Cube, there must be a suitable Rubik's Cube. If you buy, it is recommended to carefully choose the one that is particularly smooth.

First of all, to crack the Rubik's Cube, we must first understand its structure, the Rubik's Cube has a total of 6 colors and 6 sides, and each side is divided into ** blocks (6 in the middle of the block), corner blocks (8 blocks in the corners of 4) and side blocks (12 blocks in the middle of 4 edges).

Among them, there is only 1 surface of the ** block, and they are a fixed structure, so ** is a red block, so the other red colors must be concentrated on this face.

And the red block is always opposite the orange block (as the international standard dictates).

The edge block has 2 faces and 2 colors, and the corner block has 3 faces and 3 colors.

Next, we will use the letter for each face:

Then the puzzle will use letters to indicate the 1 layer or 1 side to be rotated, as well as the direction: for example: r (for the right side to turn 90 degrees clockwise), r (to represent the right side to turn 90 degrees counterclockwise), r2 (to represent the right side of the sock wheel to turn 90 degrees clockwise twice).

Finally, it should be noted that the name of each side is relative, for example, f is the front, which is the side facing oneself when holding the Rubik's cube, if you rotate the imitation to the other side, then there is a new side to become the front.

There are many ways to restore <> Rubik's Cube, but here's one of the easier ones:

Find a block with the same face color and place it in the top center, then find the two blocks next to it and place them in the correct position.

Next, find an unhomed edge, place it on the right-hand side, and execute the formula r u r' u', which allows the prism to be put in place and leave the other blocks unaffected.

Then, find a corner block, place it in the lower right corner, and execute the formula r u r' u r u2 r', which allows the corner block to be put in place and leaves the other blocks unaffected.

Repeat steps 2 and 3 until the restore is complete.

It should be noted that the restoration of the Rubik's Cube requires patience and carefulness, beginners can follow the tutorial to practice slowly, practice makes perfect, and after more practice, they can restore the Rubik's Cube more proficiently.

The methods of restoring the Rubik's Cube are "layer first" and "corner first".""Prism first" and so on.

Rubik's Cube restoration refers to the process of restoring the shuffled Rubik's Cube to its original appearance, which can be completed in 7 steps. There are many ways to restore the Rubik's Cube, such as "layer first", "corner first", "edge first" and so on.

The layer-first method refers to dividing the Rubik's Cube into three layers: the bottom layer, the middle layer, and the top layer, and then restoring it in layers. Steps:

6 or 7 steps; Formula amount: about 5-10 pcs; Average restore steps: 100+.

This method is most suitable for beginners to master, and after practice, the average person can use a good Rubik's Cube to achieve the level of recovery within 1 minute.

The layer-first method of restoring the Rubik's Cube is divided into six or seven stages, and the whole is "layer-by-layer reduction". The second step is to return the corner blocks of the same color. The third step is to bring the middle edge blocks into place.

The fourth step is to put the top edges in place. The fifth step is to bring the top edges into place. The sixth step is to bring the corner blocks on the top layer into place.

The seventh step is to return the top layer to the corresponding corner block.

Rubik's Cube Introduction:

Rubik'S cube), also known as Rubic cube, is a mechanical educational toy invented by Hungarian architecture professor and sculptor Rubic Airne in 1974.

The Rubik's Cube has a variety of gameplay methods such as racing, blind twisting, and single twisting, and its popularity has not diminished to this day, and it is one of the most popular intellectual games that will hold large and small events every year. 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 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.

1. The first step: the bottom edge is returned, as shown in the following figure

2. The second step: the bottom corner is home, as shown in the following figure:

<>3. The third step: the second layer of edges is homebound, as shown in the following figure:

4. Step 4: The top edge surface is at a loss of base, as shown in the following figure

5. The fifth step: the top corner position, as shown in the following figure:

<>6. The sixth step: the top edge is homecoming, as shown in the following figure:

7. Step 7: Top angle homing, as shown in the following figure:

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 lower two layers of the four sides are complete, 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 on the side, and it is judged according to the color of the side whether it moves to the left side of the middle layer or moves 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 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).
