Learning LBL, also known as the beginner's reduction method, is divided into seven steps. There are a total of seven formulas, uru'r'u'f'uf. u'f'ufuru'r'This is the formula for turning to the second layer.

furu'r'f'. u'ru'2r'u'ru'r'. r'u2rur'ur.

Here is the formula above. lu'rd2r''rururu'r'u'r2.This is the last layer of formula, and the first layer and the bottom surface need to be explored by themselves.

You can also find someone to teach, and there are formulas in the back. However, formulas only correspond to the situation in which the formula appears.

Step 1: Make the standard cross of the bottom layer of the defense filial piety (from the yellow and white cross to the standard cross) Step 2: Restore the bottom layer of the complete layer (on the basis of step 1, restore the bottom corner block) of the stove void.

Step 3: Restore the first two layers (restore the second layer of prisms on the basis of step 2) Step 4: Make a top cross (make a top cross on the basis of step 3) Step 5:

Restore the top layer (restore the top layer corner block on the basis of step 4) Step 6: Make a multi-sided concave character (adjust the top side of the manuscript on the basis of step 5) Step 7: Completely restore the entire Rubik's Cube (completely restore the top layer on the basis of step 6) <>

Rubik's Cube Tutorial Formula Formula Seven Steps:

1. Right reverse, upward transverse, forward reverse, upward reverse; 2. Right reverse, downward reverse, right converse, downward transverse; 3. Ascending, right, up, right, up, up, forward, up; 4. Forward Shun, Right Shun, Shang Shun, Right Reverse, Upper Reverse, Forward Reverse; 5. Right Shun, Shang Shun, Right Reverse, Shang Shun, Right Shun, Shang Shun, Shang Shun, Right Reverse; 6. Ascending, right, up, left, up, right, up, left; 7. Right reverse, downward reverse, right shun, lower shun.

After practicing the Rubik's Cube for a long time, you will become proficient. First of all, before playing, you need to know what is a corner, which is the middle, and what is a corner block, which is the corner on both sides. Before playing, be sure to practice the formula proficiently.

The seven-step reduction formula of the third-order limb movement cube is as follows: 1. Right reverse, upward reverse, forward reverse, and upward reversal. 2. Right reverse, downward reverse, right converse, downward transverse;

3. The formula for the first case is: (up, right, up, right, up The formula for the second case is:

Up, up, up, up, up, up, right, up, right). 4. Forward Shun, Right Shun, Shang Shun, Right Reverse, Upper Reverse, Forward Reverse; 5. Right Shun, Shang Shun, Right Reverse, Shang Shun, Right Shun, Shang Shun, Shang Shun, Right Reverse;

6. On the Shun, the right thing is hungry and annihilated, on the reverse, on the cover Chong left reverse, on the Shun, on the right, on the reverse, on the left. 7. Right reverse, downward reverse, right shun, lower shun.

The seven-step reduction method of the third-order Rubik's Cube is as follows:

First, the bottom cross.

The front and back are shown in the figure below.

Choose a face that you want to put together at the beginning, that is, which color you like, first put together the 9 pieces of that side, this step is not to put together, but to spell out a cross.

Second, the bottom surface restoration.

It is still white as the bottom surface, and there is no formula like the first step, which is a simple corner block movement.

Third, the middle layer is restored.

At the end of the first two steps, the bottom 9 blocks are all in place, drop the Rubik's cube one by one, so that the bottom is really facing down (white down), and then it has been facing down.

If it's the left side, as shown below, then use the formula: Formula :u'l'ulufu'f'。

If it is the right side, as shown below, then use the formula : Formula: uru'r'u'f'uf。

Fourth, the top cross.

In the top cross process, you only need to observe the edges of the top surface, so the example diagram of this step is replaced by a plan view (top surface). There is still only one formula for this step, the formula f4: frur'u'f'。

However, for different cases, you need to use the formula 0 3 times to restore (the top surface is still t in the formula, but only the top plane view is shown here).

4. The word "ten": that is, the central block and the 4 edges are correct, which is the goal of this step (situation 4).

In addition, because after a small turn in the formula, it is situation 3, and there is no need to rotate again, so in fact, the f and f' in the formula can be omitted, and you will be familiar with it after practicing more.

Fifth, the top surface restoration.

If you turn it a few more times, you will find that in fact, this equation 5 is to make the four corner blocks of the top surface cross transform, as shown in the figure below.

Sixth, the top-level intermediate process.

At the end of the fifth step, the top color is correct, but the 9 colors of the top layer are not necessarily right, this step is the intermediate process, the purpose is to make the top layer only the edges are wrong, and the corners are right. There is still only one formula, the formula F6 : RB'rf2r'brf2r2。

7. Top-level restoration.

This is the last step of the third-order Rubik's Cube, which puts the 4 edges on the top layer into place.

The formula can be the same as in 5, which is written as up, right, up, left, left, right, right, and 180. Formula f7: ru'rururu'r'u'r2。

The seven-step reduction method of the third-order Rubik's Cube is as follows:

Tools used: Third-order Rubik's Cube.

Step 1: Let's restore one side first, and then randomly select one side to restore.

Step 2: After one side is restored, we restore the first layer and restore the first layer.

Step 3: After the first layer is restored, we restore the second layer and restore the hidden heart block.

Step 4: When the two layers are restored, we will turn the Rubik's Cube over and restore the last layer, first putting together the top into the shape of a "fish" or "cross".

Step 5: After that, we build on the previous one, restore the top.

Step 6: After the top layer is restored, we will restore the top circle, and first restore the corner blocks.

Step 7: Finally, our marketers restore the entire Rubik's Cube, and the Rubik's Cube is restored in seven steps.

Benefits of the Rubik's Cube

1. Exercise eyesight. In the early days of playing the Rubik's Cube, everyone chose the basic third-order Rubik's Cube, and there are many variations of the third-order Rubik's Cube, and you can observe it through your eyes and identify the position of each Rubik's Cube.

2. Exercise endurance. Some people are in a hurry to get it out quickly, and if they are in a hurry, the more they can't turn it out, so they need a certain amount of patience to overcome these irritable moods, and slowly understand the secrets in the Rubik's Cube.

3. Exercise your fingers. When playing the Rubik's Cube, you need to use both hands together, so that you can exercise the flexibility and coordination of your hands.

4. Memory. When recovering the Rubik's Cube, you need to memorize some formulas, if you want to improve the speed of restoration, formulas are essential, and you also need to strengthen the practice, so that you can exercise the brain's memory ability.

5. Reaction speed, if you pursue the reduction speed when restoring the Rubik's Cube, this requires the brain's reaction speed to be relatively fast.

The three-order Rubik's Cube seven-step reduction method (CFOP method) is a commonly used method of reducing the third-order Rubik's cube, which is divided into seven steps. 1.Underside:

First, restore the bottom surface and form a large square of one color into a small square. You can find a center block and then restore it based on the edge and corner blocks around it. 2.

Cross: Forms a cross on the underside so that the side blocks around it are the same color as the center block. You need to find the edge blocks that you can place, then flip and rotate them until you put all the edge blocks together into a line.

3.Lower two layers: Use formulas or tricks to restore the lower layers.

4.Top Source Macro Cross: Group the top four center blocks into a single cross, and make the edge blocks around them the same color as the center block.

5.Top Corner Positioning: Find a corner block that is not in the correct position and move it to the corresponding position at the bottom layer.

6.Top Corner Block Homing: Move the three corner blocks to the correct position in turn.

7.Top Edge Block Homing: Moves the remaining two edge blocks to the correct position.

The above are the basic steps of the CFOP method, and each step has corresponding formulas and techniques to apply. It takes a lot of practice to become proficient, and the time to restore the Rubik's Cube also needs to be constantly improved.

Summary. The seven-step reduction method is a relatively simple three-order Rubik's cube reduction method, and the following are the specific steps: Solve the bottom cross:

Find the color of the bottom center block, place it facing up, and then find the four corner blocks so that they are the same color as the center block. Then find the four edges and place them next to the center block. Complete the ground floor:

Find the correct position of the underlying corner blocks and edges and place them. Solve the middle edges: Find the incorrect edges on the middle layer and move them to the correct position.

Solve the top cross: Find the color of the center block of the top layer and place it facing up. Then find the four edges and place them next to the center block to form a cross.

Complete the top corner block: Find the correct position of the top corner block and place it. Adjust the top edges:

Find the incorrect color of the top edge and move it to the correct position. Complete the Rubik's Cube: Finally, adjust the orientation of the top corner blocks to complete the Rubik's Cube.

Complete the Rubik's Cube: Finally, adjust the orientation of the top corner blocks to complete the Rubik's Cube.

The Rubik's Cube is known as the Mozhen Demolition Cube in Taiwan Province of China, the Twisted Dice in Hong Kong SAR of China, and the rubik in foreign countries's cube. Invented in 1974 by Hungarian architecture professor and sculptor Rubik Airne, the mechanical educational toy was originally called the Magic Cube and was sold by Ideal Toys in 1980's cube。
