Special Rubik s Cube Teaching, all Rubik s Cube tutorials

Quite simply, the most popular method is the single formula method. From beginning to end, it's a formula that is used over and over again.

The formula is:

1. Straighten the Rubik's Cube, facing your quadrilateral (F), the bottom line D, the right line R, and the left line L. (Note that this is lowercase.) Uppercase letters still represent faces).

2, D to R, D to L, R to D, L to D. (can be written as a "top up and down formula").

Explanation: 1 For example, "D to R" means to turn the bottom line 90 degrees to the right to replace the original right line.

3 The effect of each execution of the formula is: rotate the bottom 2 corners closer to you clockwise, and rotate the bottom 2 corners away from you counterclockwise. At the same time, the center block of F is transposed with the center block of D, and the center block of R is transposed with the center block of L.

Thought Process: (Replicated below).

1) Turn the side for the better: First of all, we must complete one side first, and we will use the green side as the standard for the following example.

Start by finding the center of the green side. The center is the square in the middle of each side, and there are four corner blocks next to each center. Turn the green corner to the same side as the green center, and pay attention to the green corner block, except for the green side, the other colors should be the same color on the same side.

For now, just pay attention to the other colors that have green corner blocks).

2) Turn the following four corners: Observe which two of the following four corners should be turned clockwise and which two should be turned counterclockwise.

Place the two corners that you want to turn clockwise under the side facing you (the side that was turned is still on top), and the two corners that you want to turn counterclockwise will be under the back with your back facing you.

Use the up-and-down formula once and the angle will turn better.

The special case is: if two of the following four corners have been turned, what should the other two corners do if they are one straight and one is reversed?

Just remember: use the up-up and down formula once, so that the two corners that are already good should be turned off, and the other two corners should not be turned well, so that the four corners can be turned in one direction, and then apply the up-up and down formula again.

3) Swap Center: The last part left is the swap center.

First of all, the three centers to be replaced are just connected in a straight line. Discovery: Center A goes to Center B, Center B goes to Center C, and Center C goes to A.

Then face the center of C (the center in the middle, where you want to go) and put the center of B (the center in the middle) underneath so that the center of A is on the back. Make the Up-Up and Down formula once, then keep it facing up, rotate the whole block horizontally 180 degrees, face back, and do the Up-Up Up and Down formula again so that the three sides will be reversed.

What if these three faces form a triangle? Similarly, center A goes to center B, center B goes to center C, and center C goes to A.

Facing the center of C, put the center of B that you want to go to C underneath, and then turn it around first, and turn the center of A to the back;

After transferring the three centers as mentioned above, the later centers are transferred back.

In addition, there is a new one: front and bottom center exchange, left and right center exchange. Just make the up and down formula three times in a row.

Four-axis first-order, this is relatively easy, only one formula is needed [up and down], and you can use it repeatedly, I just learned it.

Up and down: There is a second half up 120, the left back half up 120, the second half down 120, and the left back half down 120

I would like to ask: can it be transferred? It looks like only the horns can turn.

Even if you twist it randomly, it can be unscrewed out very quickly.

The tutorial for the Rubik's Cube is as follows:

1. Understand the structure of the Rubik's Cube: The standard Rubik's Cube is composed of 3x3 small cubes, and each side has a different color of the wheel. The center block is fixed, while the edge and corner blocks can be rotated.

2. Scramble the Rubik's Cube: Scramble the Rubik's Cube to mix the colors together. This is the first step to start solving the Rubik's Cube.

3. The first layer of cross: find the color of the bottom center block and form a cross shape around it. This is the basic step of solving the Rubik's Cube.

4. The first layer of corner blocks: determine the position of the corner blocks of the bottom layer according to the bottom cross and place them in the correct position. This step requires mastery of basic formulas and techniques.

5. The second layer of edge blocks: After the first layer is completed, place the side blocks of the middle layer on the correct bit fiber server. This step requires some algorithms and skills.

6. Top layer cross: form a cross shape on the top layer, so that the color of the center block of the top layer is the same as that of the center block corresponding to the bottom layer.

7. Top corner block: Place the top corner block in the correct position, so that the color of each corner block matches the color of the top center block.

8. Top-level edge block: By using specific formulas and techniques, place the top-level edge block in the correct position.

9. Adjust the top layer corner blocks: If the top layer corner blocks are in the correct position but facing the wrong direction, they can be adjusted by the male wax vertical lift.

10. Adjust the top edge block: If the top edge block is in the correct position but the color arrangement is wrong, you can adjust their position through the formula.

Benefits of playing Rubik's Cube

2. Enhance concentration: Solving the Rubik's Cube is an activity that requires a high degree of concentration. In the process of solving the Rubik's Cube, it is necessary to maintain concentration, observe and analyze each step in detail, and perform accurate and rapid finger manipulation.

This helps in training and improving the ability to focus and focus.

3. Exercise patience and perseverance: Solving the Rubik's Cube is not a simple task and may take a long time to complete. By persevering and facing difficulties, you will gradually develop patience and perseverance, and learn to persevere in the pursuit of your goals.

4. Relax: Solving the Rubik's Cube is a good way to relax. When you focus on the Rubik's Cube and concentrate on the puzzle game, you can be distracted, stress reduced, and experience a state of flow.

First of all, we need a Rubik's cube that is out of order. First of all, we carry out the completion of the bottom cross, this step is actually no formula, just remember that our purpose is to align the four edges of the bottom surface to the corresponding position, and remember that the above mentioned rotation of a face will only have 8 blocks of movement, you can complete. After the cross is completed, we continue to turn this first side.

The idea of this step is to first look at the top color (that is, the color of the center block of the top surface), and then find the one that does not have this color among the four edges on the top layer, if you find it, then transfer the edges of the third layer to the surface of the corresponding color, and then see what color this block is on the top surface. Let's take a look at the reduction method of the second layer, there are many cases in this step, just remember how to hold the Rubik's Cube in each case, because there is only one formula (and the good thing about this formula is that the top surface will only turn counterclockwise!). Up, right, right, down, right, up, right! to restore. Then let's restore the top surface, first of all, we still apply the formula, first complete the cross: front right lower left upper right lower front left lower , and then capping:

Up, right, right, down, right, up, right! Finally, let's take a look at the reduction formula of the last layer, after ensuring that the color is consistent, apply the formula, concave: up and down right up front left down front left bottom front left bottom back left down up front right down front right down down down, and then build the concave face by yourself, apply the above formula to do it once.

After that, we move to the left: up, left, up, right, right, up, right, left, left, right

A complete Rubik's Cube is obtained.

1. Take a Rubik's cube and shuffle it. The center block of the third-order Rubik's Cube does not become, and no matter how it is rotated, the white center block will always be opposite to the yellow center block. The other colors are also fixed and opposed.

2. The other side of the white block on the white cross should be the same color as the center block of the second layer. You can use the formula of upper, left, lower, and right-upper, and put the same side of the center block of the second layer as the center block of the first layer in the palm of your left hand to make the formula. Do it back and forth a few more times, and you can recover.

3. The corner blocks of the first layer are determined by the corner blocks of white and the other two colors. For example, the red, green, and white corner blocks, put this piece in the middle of the red and green center block, and do the formula of up, left, bottom, and right to restore, and the other corner blocks are also restored according to this formula.

4. The corner blocks of the second layer are restored, find the same color for the third time, as shown in the figure, red and blue blocks, rotate the blue blocks in the opposite direction of the blue center block, use your left hand to do the up, left, down and right, and the white corner blocks rotate on the third layer. Then use your right hand to do up, left, down, right. The second layer of corner blocks is restored, and the other faces are restored according to the same operation method.

5. Look at the third layer of yellow, whether it is a right angle or a horizontal line in the middle, or the yellow in the center of the market. Rotate the first layer in front of you 90 degrees to the right. Use your right hand to do up, left, down, right, and left to rotate back. Spin out a yellow cross.

6. On the basis of the cross, on the right hand side, do the formula of the lower right upper right lower right upper right upper right, and the shape of a small fish will be obtained. Do the formula again on the basis of the small fish, and the yellow side will be completely restored. Under the formula is the first layer on the right-hand side, and on the right is the first layer on the yellow side.

7. Now only the edge blocks of the third layer are of different colors, so it is time to make a long formula to recover. Rotate the yellow face with the god facing you, and rotate the white side back 180 degrees up, right, up, down, and down, and 180 degrees. Unify the color of the corner blocks, as shown in the picture.

8. After the corner block is unified, the cultivation hand should now restore the center block. Down, left, down, right, right, right, up, left, "right rotates 180 degrees". Rubik's Cube restoration.

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

1. 8 Luqing corner blocks: interchangeable positions (8!) can also flip the direction (38), but you can't flip a corner block alone (1 3), so you have 8!37 variations.

2. 12 edges: Disturbing Xichang can swap positions (12!) can also flip the direction (212), but you can't swap a pair of edges (1 2) alone, and you can't flip a pair of edges (1 2) alone, so you have 12!

212 2 2 ) variations.

3. 6 central blocks: fixed and immovable.
