What are the rules of the Rubik s Cube and what are the rules of the Rubik s Cube?

The Rubik's Cube is a Hungarian architecture professor and sculptor Erno. Rubik invented the mechanical educational toy in 1974, hence its English name Rubik's cube。He found 26 small cubes of the same size rotating around the same central block, and after he turned the cube a few times, it was difficult to restore the magic cube, and Rubik soon patented his invention, which went on to become popular all over the world.

Our common Rubik's Cube is the 3x3x3 third-order Rubik's Cube, which is a regular 6-sided body with 6 colors, composed of 26 pieces with 8 corner blocks; 12 edges; 6 central blocks (connected to the central shaft bracket), the Rubik's Cube was the most popular in the 1980s and has not faded ever since. Soon after, a number of similar toys appeared, some by the inventor Rubik and others by others. Includes 4 4 4, 2 2 2 and 5 5 5 versions of the Rubik's Cube.

Let's first enjoy the 2008 WCA Guangzhou Rubik's Cube Competition in Zhuhai a junior high school third-grade student [screen name: little ghost] of the wonderful ** clip, he only took seconds to restore the third-order Rubik's Cube, the little ghost from the beginning to achieve such results, it took less than a year, want to become a Rubik's Cube restoration master like him, before learning, please understand and master some basic knowledge of the Rubik's Cube, which will be very conducive to quickly master the recovery skills and methods of the Rubik's Cube, good, Let's embark on a joyful journey of Rubik's Cube restoration.

1. The most popular color scheme of the Rubik's Cube.

Yellow on the top and white on the bottom.

Front blue, back green.

Orange on the left and red on the right.

Let's first look at the center of each side of the Rubik's cube, which will not move, that is, no matter how you turn the Rubik's cube, the side of the center color must be the whole side of the same color. Then look at the corners, the four corners of each side of the Rubik's cube have three colors, and the four pieces with the center color in the shape of a cross have two colors, and the direction corresponding to these colors is also fixed, for example, the top, bottom, and left sides of this piece are blue, red, and yellow respectively, so according to.

The core of the third-order Rubik's Cube is an axis and consists of 26 small cubes. There are 6 central squares, which are fixed and have color on only one side. 8 corner squares can be rotated.

12 edge blocks can also be rotated. When the toy is in **, the arrangement of the small cubes makes each side of the large cube have the same color.

When one side of a large cube rotates horizontally, the single color of each adjacent side is destroyed, and a new pattern cube is formed, and then it is rotated and changed again, forming that each side is made up of small squares of different colors.

The gameplay is to rotate the shuffled cube to six sides into a single color as quickly as possible. If you can turn the Rubik's Cube 3 times in one second, not counting repetitions, it will take 454.2 billion years to turn all the changes in the Rubik's Cube, which is about 30 times the current estimate of the age of the universe.

Imitation tips for beginners

1. For the top layer of the cross, restore the top layer of the edge.

2. Restore the top corner block.

3. Restore the middle layer of edges.

4. Restore the bottom edge of the bottom cross to the bottom layer.

5. Flip the bottom corner blocks and align the bottom colors. Stage 6: Adjust the position of the bottom corner block to complete the restoration.

Beginners play the Rubik's Cube first using the third-order Rubik's Cube layer first restoration, which is divided into six stages.

Of course, the Rubik's Cube has rules to follow, otherwise how can those masters screw it quickly.

Nowadays, people have a lot of misconceptions about the Rubik's Cube, such as playing the Rubik's Cube requires memorizing formulas, such as the Rubik's Cube is just a toy. But in fact, the Rubik's Cube is not that simple. Let's take a look at the two seasons of the strongest brain has six Rubik's Cube projects, the strongest brain is a scientifically rigorous variety show that "makes science popular", and a toy has appeared on the stage of the strongest brain six times, and the charm of the Rubik's Cube can be seen.

Hand-eye-brain coordination. It requires the coordination of our hands, eyes and brains, the hands are turning, the eyes are finding, the brain is thinking, and it is not for a moment. And the Rubik's Cube requires strong logical thinking, which is the left brain, which requires a quick response and sensitivity to colors, which is the right brain.

A small toy, the left and right brains are exercised.

Improve your child's ability to concentrate and execute. The youngest child I've ever seen playing with the Rubik's Cube is over 2 years old and recovers in more than 20 seconds. Therefore, age is not the basic factor that affects whether children can learn the Rubik's Cube, so what is?

It's focus and execution. A child can't learn to play the Rubik's Cube just because he has enough concentration. In fact, the Rubik's Cube is not difficult, as long as you follow the teacher's method step by step.

Therefore, the most intuitive improvement of the child's learning through a period of Rubik's Cube is that he can sit still. And when I go home, I stay away from the ipad, and the mobile phone rotates around with a Rubik's cube all day long.

Improve your child's memory and learn how to memorize it. The advanced method requires memorizing 119 basic formulas, and this is when we teach children some memorization methods. A formula consists of more than 20 English letters and a figure, if a child can remember 119 formulas and use them flexibly, are you afraid that he will not be able to remember English words?!

Teach children how to learn. In fact, the principles of many Rubik's cubes are the same, for example, after learning the third-order Rubik's Cube, many Rubik's cubes can be played, which is very similar to our mathematics. Mathematics is that the teacher teaches an example problem, and then asks the child to do it after it is transformed, and the Rubik's Cube also uses this idea of transformation.

I am a mathematics major, and the Rubik's Cube is actually a model one by one, which can be fully applied to daily life and learning.

Playing the Rubik's Cube is regular and verbal. First you have to make a layer of crosses, then all the bottom layer, then the second layer (middle layer), and finally the top layer. If you don't understand, there is a ** demo on the Internet.

There is no pattern to the Rubik's Cube. There are formulas, though.
