How to practice the technique of twisting the Rubik s Cube?

First of all, this magic friend, the Rubik's Cube is a hobby, if you are in a hurry for quick success, but you can't be fast, you know, to become a master of about 15 seconds, it usually takes about 1 year of practice (2-3 hours a day to ensure 2-3 hours), so, don't worry.

Then, if you still use a few basic algorithms taught on the Rubik's Cube station, it can't be fast, you have to memorize the formula, the most commonly used is CFOP, you go to MF8, Rubik's Cube Paradise, etc.** can be seen, there is really no, you leave an email and I will send it to you.

Finally, diligence can make up for clumsiness, don't worry.

First, the technique is to turn with your fingers, not with your palms, and comprehend it yourself. If you practice the technique, you can make a restored Rubik's Cube 6 times r,u,r',u', if you have something to do, you can practice like this.

Second, the competition is a 15-second observation time, and in this short 15 seconds, the average person can only see how to make a cross with the shortest number of moves. As for your statement that "after you start, you will screw the cube without looking at it" is wrong, every player has to watch it, but the less time you have to watch, the faster you can restore the Rubik's Cube, this is the Rubik's Cube competition.

1.The technique is to better twist the Rubik's Cube. Manipulation refers to using your fingers to pluck the Rubik's Cube, rather than twisting the Rubik's Cube with your whole hand. The specific technique is relatively easy to understand, and there are many of them, so you can know it at once.

2. There are fifteen seconds before the speed twisting competition, the players are observing the relative position of the Rubik's cube, most of them are learning the CFOP layer first advanced method, they will blindly twist the low-level cross, and further blindly twist the first group of corner blocks. Blind twisting competition is memory...

There are many kinds of advanced formulas, at present, the speed twisting CFOP is the mainstream liberation, and there are many other bridges, CFCE, etc. If you're a scholar, you can go check out CFOP.

My speed is about the same as yours, I and my classmates learn the Rubik's Cube to see the Internet**, let's just say the third-order bridge method, there is only that** [estimated to be a few more now], but I and my classmates learned it, she only took more than forty seconds, I felt that her fingers moved very fast, and she saw it quickly, and asked her why it was so fast, she said that it was to follow the teaching of the twist There is also a classmate who is also very fast, he said that he practiced a technique repeatedly for a week, and now I also want to practice the technique o( o

Just practice a lot and think about it a few more times.

It's important to think about it.

Nothing regular.

The so-called winner of F wins the world, and the master of speed twisting can often complete 4 groups of F coherently, which looks like a formula, which requires observation, to be able to find the next group of angular blocks at the fastest time, and to return to the position with fewer steps.

As for how to increase the speed and reduce the steps, it is necessary to "let your eyes follow your hands", most people's hand speed is too fast, so that the observation cannot keep up, resulting in the need to stop and find the next set of corners, wasting time, and moreover, too fast hands will often make you unable to solve a set of corners in the optimal way. To put it simply, slow down the hand speed (let's do the hand handicap o together) until you can do the 4 sets of F together, hold on for a while, and you will be rewarded.

The third-order Rubik's Cube speed twisting tutorial is as follows:

The bottom angle homing formula is (r u r'）、f'u'f）。

The formula for the homing of the middle edge is (u' f' u f）、（u r u' r'），u r u' r'）、u' f' u f）。

The formula for apical surface homing is f(r u r' u'）f'。

The formula for the homing of the apical angle face is r' u2 r u r' u r、u' r u'u' r' u' r u' r'。

The formula for apical prismatic homing is (r u' r）（u r u r）（u' r' u' r2）。

3rd Rubik's Cube Strategy:

When the 3rd order Rubik's Cube is spelled, it is necessary to spell out a top-level cross first, and then put the entire surface together, and then spell the other four corner blocks, and pay attention to the colors when fighting one by one.

Then the middle side block is homed, turn the white side downward, find the red and green edge blocks, and turn the Rubik's Cube according to the formula to make the side blocks return to position.

Adjust the top layer of the side block upwards to make a yellow cross, the top layer does not appear yellow cross, and it can be repeated according to the formula.

Adjust the yellow corners of the Rubik's Cube to the cross, position the yellow blocks at the four corners, and adjust the color blocks on the sides to the corresponding positions.

Rubik's Cube Quick Twisting Method:

A few years ago, a group of people at Google verified that an arbitrarily twisted Rubik's Cube could be restored in less than 20 steps. However, if the average person wants to restore any Rubik's Cube in 20 steps, they must remember a huge ** (about 8EB, one EB is about one million TB), which can only be done by having an all-knowing and all-powerful God and its analogues (such as the head of the regiment, Chun Ge or Gauss), so the number 20 is also called the "number of God" of the Rubik's Cube.

Of course, there is not only one Rubik's Cube. The easiest way to change this is to increase the "side length" (or order) of the Rubik's cube. The original Rubik's Cube is a 3rd order, which is a cube of 3 3 3.

We can extend to Tier 4 (4 4 4), Tier 5, all the way up to Tier 7, and there have even been witnesses of the Rubik's Cube of Tier 11 nuclear raids. The larger the order of the Rubik's Cube, the more complicated it will be, the more steps it will take, and the greater and more difficult it will be to calculate.

Later, a group of mathematicians led by Erik Demaine at MIT actually said that they had found the number of God in any order of the Rubik's Cube, and they also gave a recovery algorithm that required the number of steps not far from the number of God!

Here's how:

1. Since it is a quick twisting tutorial, it is assumed that those who are absent from the bad game can complete the Rubik's Cube independently. So here is only the introduction of the advanced gameplay of speed screwing.

It should be emphasized here that in the process of speed twisting, the technique is very important, and only in accordance with the scientific fingering can there be a faster speed, which can be referred to the following ** explanation. The color and fingers must be right.

Therefore, the first step of the bottom cross, that is, the cross step, will not be specifically introduced, but only to say that the bottom cross is mainly completed within 8 steps.

2. The second part is F2L, specifically the first two slave services, with a total of 41 formulas, and the specific situation is compared with the following figure.

3. The third part is OLL, that is, the top layer of full color, and through this step, the top layer of colors are piled up into yellow. There are a total of 57 formulas for this step, as shown in the figure below.

4. The fourth part: PLL is the top-level homing. In this step, adjust the cube on the top level of the cube to its proper position. There are 21 formulas used, as shown in the figure below.

The Rubik's Cube Quick Twist tutorial is as follows:

Tool: Second-order Rubik's Cube.

1. First restore the bottom corners: this step is to restore the 4 corners of the bottom layer.

2. Use algorithm 1 to the right for white, turn to the right first, and feast on r u r2 r u r2.

3. Use algorithm 2 for white forward, turn the front first, f2 u2 f u f2 u2 f.

4. Repeat 4 corner blocks, and you can do a good job of the bottom layer.

5. Then restore the top color: this step is to restore the color of the top surface of the 4 corner accompaniment blocks.

6. Situation 6 is to use formula 2-2 first, in other cases use formula 2-1 first, and in other noisy situations, use formula 2-1 first.

7. Then restore the top layer of the corner block: if there is a situation like this, rotate the corner block of the same color to the position facing you.

8. Use this algorithm again: r b2 r f2 r2 b r f2 r2 r2, and you can complete the restoration.

Pseudo-cross method: take a Rubik's cube and make m'2 u2

m'2, at this time, I found that the opposite two positions of the cross were reversed, this is the pseudo-cross, that is, the color is temporarily reversed, and how to apply it I give a scramble (white on green before scrambling) b2 l2 r2 u

r2 d2 b2 u r2 b2 u l b u' f2 d' b2 u2 l2 u2。

Solution: (before yellow on blue) r l2 f'At this time, the cross is completed, and we can directly revert to the oll step, here we need to note that our cross also needs an m'2u2 m'2 to restore, this step can be interspersed after the completion of F2L, or after the completion of OLL, note that it should be completed before PLL.

Whether to use pseudo-crosses or not depends on whether you can predict the first set of F2L, if the difficulty of scrambling is far greater than your ability to predict, using pseudo-crosses can reduce the burden. If the first set of F2L can be easily predicted using the pseudo-cross method and it is difficult to do it normally, then the pseudo-cross method is obviously more profitable at this moment.

1. 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 blocks in the middle), corner blocks (8 blocks in 4 corners) and side blocks (12 blocks in the middle of 4 sides).

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.

2. Next, we will use letters to represent each face.

3. Then the solution strategy will use letters to explain the 1 layer or 1 side to be rotated, as well as the direction: for example: r (on behalf of the right side clockwise 90 degrees), r (on behalf of the right side 90 degrees counterclockwise), r2 (on behalf of the right side clockwise 2 times clockwise 90 degrees).

4. 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 the imitation is rotated to the other side, then there is a new side to become the front.

5. First put the white block in the middle (the one with a rubiks logo) on 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).

6. Then the white corner blocks are put in place.

7. 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.

8. 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.

9. Then adjust the yellow corner blocks to the cross, which is a bit difficult, look at the mantra prompt.

10. Usually at this time, the yellow block and the color of the side will be misaligned, according to the formula, the yellow block at the four corners will be positioned.

11. Finally, adjust the color block on the edge to the corresponding position.

Twisting the Rubik's Cube quickly, that is, twisting the Rubik's Cube's cube) is a relatively common teaching method of Rubik's cube reduction. Compared with other complex reduction methods, the quick-twisting method is easier to learn and suitable for beginners and beginners.

Here's a tutorial for twisting the Rubik's Cube:

Step 1: Create a white cross.

First, place the Rubik's Cube on the table with the white side facing up. Then, find the white center block and place it on the front. Next, find all the white edge blocks and piece them together face up into a cross shape.

When you're done, adjust all the white edge blocks to the correct position.

Step 2: Restore the white corners.

Next, restore the white corner blocks. Find all the white corner blocks, piece them together into a complete white face, and adjust all the corner blocks to the correct position.

Step 3: Create the middle two layers.

Next, build the middle two layers. Select the side of the parsley row and align it with the white side above. Then, piece together the second layer of that side until both layers of that side are complete.

Step 4: Restore the top corner block.

Next, restore the top corner block. Find all the corner blocks on the top layer and place them correctly in their respective positions. This step may require several attempts and adjustments until all the corners are in the correct position. Belt digging.

Step 5: Restore the top-level edge block.

Finally, restore the top-level edge block. Find all the edge blocks of the top layer and place them correctly in their respective positions. Again, this step may require several attempts and adjustments until all edge blocks are in the correct position.

Once you've completed the above steps, you're ready to piece together a complete Rubik's Cube. Although the quick twisting method is relatively simple, it requires a certain amount of practice and patience to master perfectly. It is recommended that beginners try to master the basic skills of each step first, and practice more in order to gradually improve the speed and skill of patchwork.
