How to calculate the order of the Rubik s cube in the shuffling order?

The letters represent the six sides of the Rubik's cube: right, r, left, l, up, u, down, d, front, f, and b

90 degrees clockwise is represented by the letter [ ].

90 degrees counterclockwise with [.]'] letters represent.

180 degrees clockwise is represented by the letter [2].

180 degrees counterclockwise with ['2] The letters represent the Rubik's Cube formula step introduction Introductory formula (layer first method):

Step 1: The bottom edge is returned to position (also known as the bottom cross, the process of correct restoration of the bottom four edges).

Step 2: Bottom corner homing (restore the four corner blocks of the first layer of the Rubik's Cube):

Equation 2-1: (r u r'）

Equation 2-2: (f.)'u'f）

Step 3: Middle Ridge Homecoming (the step to restore the four edges in the middle layer of the Rubik's Cube):

Equation 3-1: (u' f' u f ）（u r u' r'）

Equation 3-2 :(u r u' r'）（u' f' u f）

Step 4: Top edge position (also known as the top layer shelf cross, the top color of the top four edges is the same as the color of the top center block):

Equation 4: f (r u r' u'）f'

Step 5: Top Corner Face Position (the step in which the top surface color of the four top corners of the Rubik's Cube is adjusted to the top surface):

Equation 5-1:r' u2 r u r' u r

Equation 5-2: u' r u'u' r' u' r u' r'

Step 6: Apex corner homing (the other two sides of the four vertex corners of the face position are the same color as the center block of the corresponding face):

Equation 6: r b' r f2 r' b r f2 r2

Step 7: Vertice homing (the color of the other side of the four vertex ridges that have been placed is the same color as the color of the center block of the other four faces):

Equation 7: (r u' r）（u r u r）（u' r' u'r2) o, no copying!

I wish you a speedy success!

It's not very clear.

Steps. 1. Make the bottom cross.

2. Restore the bottom layer.

3. Restore the second layer.

4 do the top layer cross.

5. Adjust the position of the top edge.

6. Restore the top surface.

7. Restore the top layer, that is, 4 corners are homebed.

The above are the basic steps of the Rubik's Cube, where the order of 5 and 7 can be reversed.

It is not difficult to put back the reason for the scrambled Rubik's Cube, but it is difficult to describe it in words.

To give you a general idea.

First spell the bottom cross (generally brother hand yellow background white). After putting it together, it is as follows:

Then put together the bottom four corner blocks, such as a sliding number chart.

Spell the second layer of four edges.

<> the top edges and corners to return to the Rubik's cube.

After the Rubik's Cube is scrambled, it can be restored with the Rubik's Cube formula.

The formula for the third-order Rubik's Cube is as follows:

1. Restore one side first.

2. Restore the trapezoidal shape composed of the bottom layer and the center block of the four sides, there is no formula for the first two steps, and you have to explore it by yourself as the foundation.

3. The formula for the third step is the middle and left squares: subtract up, subtract left, add up, add before, subtract up, subtract before. Middle-right square: add up, add right, subtract up, subtract before, add up, add forward, restore the cross on the top layer.

4. The formula of the fourth step is to add before, add right, add up, subtract right, subtract up, and subtract before.

5. The fifth step is to add right, add, subtract right, add, add, add 180 degrees, and subtract right.

6. The sixth step is to add, right, subtract, subtract, subtract, add, subtract, subtract, subtract

7. The seventh step is right subtraction, bottom subtraction, right addition, bottom addition, right subtraction, left subtraction, right addition, and bottom addition. Repeat this mantra by using "add" once for each pair of upper corners, and then completing the next corner until all six sides are of the same color.

Rubik's Cube

The Rubik's Cube, also known as the Rubic Cube, known as the Magic Cube, in Taiwan, and the Twisted Dice in Hong Kong, is a six-sided cube made of elastic hard plastic. The core is an axis and consists of 26 small cubes. There are 6 of them, including the center square, which are fixed and only one side is colored.

There are 8 corner blocks that can be rotated. 12 edge blocks can also be rotated.

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

1. Return the bottom edge, choose the white side as the bottom surface, and set up a cross on the bottom layer of the Rubik's Cube. The reduction edge is to spell out a cross on each surface, and the cross is not according to the surface, but according to the layer. Return the first layer first, that is, spell out a cross on the first side.

This is very simple, but the cross must be spelled correctly, that is, the color of the four edges of the cross must be consistent with the color of the center block of the front and back, left and right.

2. The bottom corner is to restore the four corners of the first layer of the Rubik's Cube.

3. The second layer of edges is the step of restoring the four edges in the middle layer of the Rubik's cube.

4. The top edge position, when doing this step, it depends on the condition of the Rubik's cube in the hand, such as the "point": after doing this action step, it is a "small turn", then the top layer should be adjusted to the correct direction and then do this step, and so on, until the fourth step of restoring the top layer yellow to a cross Rubik's Cube is completed.

5. The top corner position is to adjust the top surface color of the four top corners of the Rubik's Cube to the top surface.

6. The top edge is in place, so that the color of the other side of the four top edges of the Rubik's Cube is the same color as the color of the other four sides where it is located. Step 6 of the order of the top four corners of the cube is complete.

7. The top corner homing is to make the other two sides of the four top corners of the Rubik's Cube that have been placed in the same color as the color of the corresponding face.

Third-Order Rubik's Cube:

The third-order Rubik's Cube (alias: magic cubes, twisting dice, English name: rubik'S Cube is a mechanical educational toy invented by Rubic Airne in 1974.

The third-order Rubik's Cube is a 6-sided cube made of elastic hard plastic, with an axis at its core, and consists of 26 small cubes. There are 6 of them, including the center square, which are fixed and only one side is colored. There are 8 corner squares (3 colored sides) that can be rotated.

12 edge squares (edges) (2 colored sides) can also be rotated. In fact, there is not only one color scheme of the Rubik's Cube, the official version is popular now, and in fact there are other versions of the color scheme.

If you want to restore the messed Rubik's Cube, you must first understand the formula of the Rubik's Cube, as long as you master the recipe of restoration, you can restore the Rubik's Cube in any state to its original state.

The specific restoration method of the Rubik's cube (taking the third-order Rubik's cube as an example):

1. Return to the bottom edge: choose a color surface as the bottom surface, make a cross at the bottom of the Rubik's cube, and then spell out a cross on each surface, first spell the first layer, and the cross must be correct, and the color of the four edges of the cross must be consistent with the color of the center block on the front and back.

2. Return to the bottom corner: restore the four corner blocks of the first layer of the Rubik's Cube.

3. The second layer of edges is in place: restore the four edges in the middle layer of the Rubik's Cube.

4. Top edge position: At this time, it depends on what the situation of the Rubik's Cube in the hand is, if it is a "point", after doing the action step of the top edge position, it is a "small turn", and the top layer should be adjusted to the correct direction, and then do the action step of the top edge position, and so on, until the top layer of color is restored to a cross.

5. Top corner position: make the top surface color of the four top corners of the Rubik's Cube all adjusted to the top surface.

6. The top edge is in place, so that the color of the other side of the four top edges of the Rubik's Cube is the same color as the color of the other four sides where it is located. 7. Top corner homing:

The other two sides of the four corners of the cube that have been placed are also the same color as the corresponding faces. After the whole adjustment is made, you will find that the Rubik's Cube has been restored.

Summary. How to put the messed Rubik's Cube back.

Powerful dismantling is possible.
