How to collect Rubik's Cube: instruction for beginners

Rarely can we afford the joy of absolute idleness when we give rest to hands, feet, head and the whole organism. More often than not, it only seems to us that we are idling. It's because the person is very active by nature. He is bored and incomprehensible amorphous movement in life. If you have a free minute, he can set himself an original goal. For example, to collect a cube Rubik. The instruction to collect this puzzle is very specific, but it is quite realistic to understand it.

Few historical facts

More than 40 years ago the Hungarian sculptor Erno Rubik showed the world his famous puzzle, which was named just by the author's surname. Then the inventor was engaged in teaching industrial design and architecture. There is a version that he invented a cube for a textbook, with which you can clearly explain the basics of the mathematical theory of groups. For students, the inventor posed the difficult task of forcing individual cubes to rotate freely on the ground without damaging the constructive unity of the puzzle. Accordingly, the first testers were friends and students of Rubik.

In 1975 Rubik's cube was patented, but only after two years the production of an industrial batch of cubes was set up. The first of them began to produce a small Budapest cooperative, which was positioned as a New Year toy Rubik's cube. The instruction for the assembly was not attached, but the object was enticed by the abundance of flowers and its mysteriousness. The toy became truly universal and was offered to all categories of the population. The second burst of popularity occurred when the cube saw in the hands of the waiter German businessman Tibor Lakzi, keen on mathematics. He began to promote the product in tandem with Tom Kremer - a successful inventor of games. Together they managed to launch a "cubic" invasion and release more than 100 million toys.

Time frame

So, for how long can I collect a Rubik's cube? The instruction does not particularly appeal to beginning "puzzlers". That's why it will take long and painful to collect. Many do not stand up and throw started halfway. But the assembly of this puzzle perfectly develops the motor skills, stimulates the work of thought, calms and helps to understand yourself. Over time, people understand that at random to assemble a puzzle is very difficult. We have to resort to proven algorithms. Many "sit down" and switch to high-speed assembly. Such people are called "speedcubes", and the process itself is called "speed-kubing". Even official competitions are held under the auspices of the World Association of Cubes. To date, set a world record of 5.55 seconds. It was installed by Mats Wolf. Before him, the world record belonged to Felix Zemdegs and was 5.66 seconds. According to unofficial data, he achieved the result in 4.79 seconds.

For beginners

So, you have a Rubik's Cube in your hands. The assembly instruction has not been studied by you yet and you want to figure out how the puzzle works. The toy has 6 sides of different colors. When buying, all sides are assembled and have cubes of the same color. Give a fancy to clear up and a minute spin the cube on all axes. As a result, before you - an intricate puzzle, which, it would seem, will not unravel. Many recommend that before the direct assembly, completely dismantle the cube on the part to ensure the correctness of the mechanism. If everything is true, then you can proceed to the process. The assembly for beginners consists of seven stages, each of which is quite achievable even for the child.

Step-by-step instruction: how to assemble Rubik's Cube

You will need to focus on the white side. Imagine that this is the base that holds the whole structure. After each "fraud" check the white side so that its integrity is not damaged. At the first stage, collect a white cross, and where there is a white square in the center. Note that the center sectors on each side suggest which color to collect. At the second stage, you need to collect the corners of the white side. Next come the edges of the white layer, the cross in the last row. Then you need to go to the arrangement of the edges and angles of the last layer and to the rotation of the corners.

Among the most common

Very popular is the instruction for assembling the Rubik's cube by Jessica Friedrich. This is a method of high-speed assembly, which does not require the memorization of a large number of formulas. The main thing is to understand the principle. In the process, one of the parties is going to cross. The first layer is collected simultaneously with the second one. Then follows the orientation and permutation of the elements of the upper layer.

Intuition

If you do not want to memorize the formulas, then you will have to step-by-step instructions on the Rubik's cube according to Valery Morozov's technique. Here you need to learn the basic principles of assembly. First, eight corner elements are assembled. Next, four ribs in the middle layer are assembled into a cross on the side. The remaining eight edges must form the correct pair. In conclusion, six central sectors are set on their own faces.

We go on strips

If you have already tried and even managed to collect a puzzle, then you can try the so-called method of bands. It is suitable for a 5 * 5 cube, but it's better to train on a smaller version - 3 * 3.

To learn the method you need to be able to distinguish the sides and own the rotation of the cube clockwise and against it. Assembly begins with the notorious white cross. Then it must be extended to the corner elements. Your task is to achieve the coincidence of the central elements of the sides with the upper ones, which deviate from the white cross. White corner elements should be moved to the same side. An inexperienced person can master the Rubik's cube in this way. The assembly instruction for beginners of this type is not so simple, but it gives consistent instructions. Prepare for the fact that this is not an easy task.

Basic knowledge

So it turns out that many people come up with an algorithm, how to collect a Rubik's cube. Step-by-step instructions are not particularly important to them. Maybe you too will be able to invent your method? Everything is possible, but there is a basic knowledge that will be useful to every person. So, the cube has a frame - a cross, on which the central parts are fastened. All elements are mobile, and the cube itself is spinning in all directions. The base is usually taken white side, and the opposite - usually yellow. The rotation of the parts is possible clockwise, against it and at 180 degrees. Further, it is known that the simplest assembly scheme includes seven consecutive steps. The first is always the white cross

Main Stage

So, before you Rubik's cube, the instruction for beginners, and in the reserve - about half an hour. This is enough to master the basics of assembly. Initially, you should not chase time. Practice and only practice will help you become a speedcuber. In the meantime, try to master the main stage - the assembly of the cross. By the way, successful speedcubes perform it intuitively, as there are no formulas. The main thing is to find the side where the white cube is in the center. Remember, that each edge cube has two colors and accordingly it should coincide with two centers - with white and color. Now check the side with the white center for the presence of white ribs. If they are, just rotate the bottom of the cube to match the edge with the second center. Now look at the opposite side: if there are white edge faces, then they are quite easy to return to the white side. The rest of the elements can be adjusted upward by lifting the cube with the white side to the top and unfolding it to the center.

Run the build process

The first two layers can be laid out quite simply. This is a very problematic moment for those who are thinking how to collect a Rubik's Cube. Instruction for beginners will be a visual aid, but as a whole this stage can be executed intuitively. The main problem with this is the installation of corner cubes in the first layer. The speedcubers have a special reception for this, which they call "pif-puff". By the way, he has his own formula. Cube always try to keep the white center (and side respectively) down. Look for a side cube that matches the colors of the border sides. Lift the side edge upwards, and then lead sideways, the opposite from that side of the cross, that "left" on the other side. The mechanism of aligning the corner cubes remains identical - the search for a cube in the color framework, the derivation of it to the desired field, and then - the removal to the side of the face with the "new" cube. After installing the corner cubes in the lower layer, you can go to the second bottom. The algorithm is similar, but the search for cubes becomes more difficult and longer. These very edge cubes are set in place using a single formula and its mirror image. Before alignment, you need to rotate the top layer and set the edge cube to the desired location. Always look for the color of the side face to match the color of the central sector of the middle layer. Yes, and do not destroy the upper white cross. If you are building a white side, then you will not disrupt its integrity a priori, but if the color side is going to, the destruction of the white cross is fraught with complete chaos in the puzzle. With such mirrored repetitions, you can completely assemble the white side and the two lower layers on each side. Plus, as a result of your work, the central sectors of the parties must coincide with the centers. Now you have the final stage - the collection of corner cubes on the upper side.

Many people in their free time collect a Rubik's cube and try to make it faster and easier than others. Since 1980, the search began for the so-called God algorithm for high-speed assembly. Mathematicians, programmers and just fans of scientific riddles are looking for a method that allows solving a puzzle for the minimum number of moves. In 2010, programmer Thomas Rokiki, mathematicians Herbert Kotsemba and Morley Davidson, as well as engineer John Detridge have managed to prove that any configuration of the puzzle can be solved in 20 moves at most. Any angle of the face is considered to be a move.
