Collect a rubik's cube for the most stupid. Quick Rubik's Cube. Values ​​in formulas

For children and adults sometimes it can seem like a daunting task how to solve a 3x3 rubik's cube. A diagram with pictures for beginners in this matter is one of the main assistants.

Also, to make everything clear and transparent, you can use video instructions. We will actively apply both of these aids in practice so that you finally learned to solve the eternal problem with the Rubik's cube.

Can you solve a Rubik's Cube? different ways and methods. You can do it in 15 moves, in 7 moves, and even in as many as 20. For many years, all kinds of smart people have been struggling to find the optimal solution to this problem. After all, the Rubik's Cube is a mechanical puzzle that lends itself to a completely logical solution. You only need step-by-step instruction, as well as a small margin of logic and patience.

Before you start, directly, the assembly algorithm, you should learn key concepts.

The very name of the toy speaks for itself - the cube consists of 6 sides (faces), 12 edges, 8 corners. The faces of the cube consist of 9 small colored elements that can rotate simultaneously, but only clockwise and counterclockwise. Letters of the Russian alphabet the names of the faces will be denoted as follows:

F - facade;

T - rear;

P - right;

L - left;

B - top;

N - bottom.

In many descriptions and diagrams, there are designations for the faces of the cube in English.

The next secret of the Rubik's Cube lies in the arrangement of small colored elements.

1. Central cubes determine the color of the entire side of the Rubik's Cube. It is these cubes that we will call by analogy with the names of the faces (F, T, P), etc.
2. Rib cubes are adjacent to two faces at once, so the name will be double (for example, FP, PV) - depending on the faces with which they interact.
3. corner cubes contain 3 letters in the name at once, since they refer to three faces at the same time (FPV).

And one more mini-secret - when you study face rotation schemes, letters without any additions will mean rotate 90 degrees clockwise, and letters with an additional sign ‘ – counterclockwise.

Understanding all these legend, it will be much easier for you to fold the Rubik's Cube and you will do it correctly and quickly. Also, for a change, you can learn how to do.

How to solve a 3x3 rubik's cube: the easiest way, assembly diagram

The easiest and most reliable way to solve our Rubik's Cube starts from the bottom cross. Collect the cross on the bottom face of the cube and proceed to the step-by-step solution of the problem, how to solve the Rubik's Cube 3x3: the most easy way, the diagram of which is right in front of you.

And, of course, the most understandable tool for building a cube will be a video lesson with detailed description experienced virtuoso.

Rubik's cube assembly scheme 3x3 for beginners in pictures

In the first stages of the practice of collecting the Rubik's Cube, we will use the same cross method, but this time we will have a cross of colored cubes on the top face. As you understand, the speedy assembly of the Rubik's Cube is waiting for you ahead, at this stage should learn to correctly determine the location of the edges and moving them in the plane of the cube.

There are different ways to assemble a cube, and now you have to learn how to solve a 3x3 rubik's cube: The scheme for beginners consists of 7 stages. Pictures describing the assembly process are available for you for each of the steps. You may spend more time on this puzzle than expected, but you will solve a puzzle that is not available to all the inhabitants of our planet! It's worth the sweat for it.

By the way, the last Rubik's cube world record the speed was set in 4.73 seconds. And it belonged to Australian student Felix Zemdegs, who beat the previous record holder by just 0.01 seconds. We have nowhere to rush in this matter, so we carefully study the instructions and begin to collect the first layer.

The principle of assembling the Rubik's Cube from the initial cross not that complicated. Here it is necessary to correctly study the location of the edges. And then - a matter of technology, as they say. We have already gone through the basic concepts and rules for assembling a Rubik's cube for dummies.

We are sure that the Rubik's Cube 3x3 for beginners in pictures helped you set your own record and in further attempts you will reduce the time to a minimum.

If all these steps and formulas seemed complicated and confusing to you, we suggest that you review the video, in which the whole process is shown in detail using the example of a virtual Rubik's cube.

Rubik's Cube Formulas 3x3: Calculate Moves

If you think the previous methods for assembling the proverbial cube were just for dumb ones, catch a few formulas.

The human intellect needs constant training no less than the body needs physical activity. The best way to develop, expand the ability of this quality of the psyche is to solve crossword puzzles and solve puzzles, the most famous of which, of course, is the Rubik's Cube. However, not everyone manages to collect it. Knowledge of the schemes and formulas for solving the assembly of this intricate toy will help to cope with this task.

What is a puzzle toy

plastic mechanical cube outer edges which are made up of small cubes. The size of the toy is determined by the number of small elements:

• 2 x 2;
• 3 x 3 (the original version of the Rubik's Cube was exactly 3 x 3);
• 4 x 4;
• 5 x 5;
• 6 x 6;
• 7 x 7;
• 8 x 8;
• 9 x 9;
• 10 x 10;
• 11 x 11;
• 13 x 13;
• 17 x 17.

Any of the small cubes can rotate in three directions along the axes, represented as protrusions of a fragment of one of the three cylinders of the large cube. So the design has the ability to rotate freely, but at the same time, small parts do not fall out, but hold on to each other.

Each side of the toy includes 9 elements, painted in one of six colors, opposite each other in pairs. Classic combination shades is:

• red opposite orange;
• white opposite yellow;
• blue opposite green.

However, modern versions may be colored in other combinations.

Today you can find Rubik's cubes of different colors and shapes.

It is interesting. The Rubik's Cube even exists in a version for the blind. There, instead of color squares, there is a relief surface.

The goal of assembling the puzzle is to arrange the small squares so that they form the face of a large cube of the same color.

History of appearance

The idea of ​​​​creation belongs to the Hungarian architect Erne Rubik, who, in fact, did not create a toy, but a visual aid for his students. In such an interesting way, the resourceful teacher planned to explain the theory of mathematical groups (algebraic structures). It happened in 1974, and a year later the invention was patented as a puzzle toy - future architects (and not only them) got so attached to the intricate and bright manual.

The release of the first series of the puzzle was timed to coincide with the new year 1978, but the toy entered the world thanks to the entrepreneurs Tibor Lakzi and Tom Kremer.

It is interesting. Since the appearance of the Rubik's Cube ("magic cube", "magic cube"), about 350 million copies have been sold worldwide, which puts the puzzle in first place in popularity among toys. Not to mention dozens computer games based on this assembly principle.

The Rubik's Cube is an iconic toy for many generations

In the 80s, the inhabitants of the USSR met the Rubik's Cube, and in 1982, the first world championship in assembling a puzzle for speed, speedcubing, was organized in Hungary. Then the best result was 22.95 seconds (for comparison: in 2017 a new world record was set: 4.69 seconds).

It is interesting. Fans of assembling a multi-colored puzzle are so attached to the toy that they find it not enough for them to assemble for speed alone. Therefore, in recent years, puzzle-solving championships have appeared with eyes closed, one hand, feet.

What are the formulas for the Rubik's Cube

Collecting a magic cube means arranging all the little details so that you get a whole face of the same color, you need to use God's algorithm. This term refers to a set of minimum actions that will solve a puzzle that has a finite number of moves and combinations.

It is interesting. In addition to the Rubik's Cube, God's algorithm is applied to puzzles such as Meffert's pyramid, Taken, Tower of Hanoi, etc.

Since the Rubik's magic cube was created as a mathematical aid, its assembly is decomposed according to formulas.

The assembly of the Rubik's cube is based on the use of special formulas

Important definitions

In order to learn how to understand the schemes for solving the puzzle, you need to get acquainted with the names of its parts.

1. An angle is a combination of three colors. The 3 x 3 cube will have 3, the 4 x 4 version will have 4, and so on. The toy has 12 corners.
2. An edge denotes two colors. There are 8 of them in a cube.
3. The center contains one color. There are 6 in total.
4. Facets, as already mentioned, are simultaneously rotating elements of the puzzle. They are also called "layers" or "slices".

Values ​​in formulas

It should be noted that the assembly formulas are written in Latin - these are the schemes that are widely presented in various manuals for working with the puzzle. But there are also Russified versions. The list below shows both options.

1. The front face (front or facade) is the front face, which is in color to us [Ф] (or F - front).
2. The back face is the face that is centered away from us [З] (or B - back).
3. Right Edge - the edge that is on the right [P] (or R - right).
4. Left Edge - the edge that is on the left [L] (or L - left).
5. Bottom Face - the face that is below [H] (or D - down).
6. Upper Face - the face that is at the top [B] (or U - up).

Photo gallery: parts of the Rubik's cube and their definitions

To clarify the notation in the formulas, we use the Russian version - this will be more understandable for beginners, but for those who want to move to the professional level of speedcubing without the international notation on English language not enough.

It is interesting. The international notation system is adopted by the World Cube Association ( world cube Association, WCA).

1. The central cubes are indicated in the formulas with one lowercase letter - f, t, p, l, c, n.
2. Corner - in three letters according to the name of the faces, for example, fpv, flni, etc.
3. Capital letters Ф, Т, П, Л, В, Н denote elementary operations of rotation of the corresponding face (layer, slice) of the cube by 90° clockwise.
4. Designations Ф, Т, П, Л, В, Н" correspond to the rotation of faces by 90° counterclockwise.
5. The designations Ф 2 , П 2 , etc., indicate a double rotation of the corresponding face (Ф 2 = FF).
6. The letter C denotes the rotation of the middle layer. The subscript shows which side of the face to look at to make that turn. For example, C P - from the side of the right side, C N - from the bottom side, C "L" - from the left side, counterclockwise, etc. It is clear that C N \u003d C "B, C P \u003d C" L and etc.
7. The letter O is the rotation (revolution) of the entire cube around its axis. О Ф - from the side of the front face clockwise, etc.

Recording the process (F "P") N 2 (PF) means: rotate the front face counterclockwise by 90 °, the same - the right side, rotate the bottom face twice (that is, by 180 °), rotate the right side by 90 ° along clockwise, rotate the front face 90° clockwise.

It is important for beginners to learn to understand the formulas

As a rule, instructions for building a puzzle in classic colors recommend holding the puzzle with the yellow center up. This advice is especially important for beginners.

It is interesting. There are websites that visualize formulas. Moreover, the speed of the assembly process can be set independently. For example, alg.cubing.net

How to solve a Rubik's puzzle

There are two types of schemas:

• for newbies;
• for professionals.

Their difference is in the complexity of the formulas, as well as the assembly speed. For beginners, of course, instructions appropriate to their level of knowledge of the puzzle will be more useful. But even they, after training, after a while will be able to fold the toy in 2-3 minutes.

How to build a standard 3 x 3 cube

Let's start by building a classic 3 x 3 Rubik's Cube using a 7-step pattern.

The classic version of the puzzle is the Rubik's Cube 3 x 3

It is interesting. The reverse process used to solve certain irregularly placed cubes is the reverse sequence of the action described by the formula. That is, the formula must be read from right to left, and the layers must be rotated counterclockwise if direct movement was indicated, and vice versa: direct if the opposite is described.

Assembly instructions

1. We start by assembling the cross of the upper face. We lower the required cube down by turning the corresponding side face (P, T, L) and bring it to the front face with the operation N, N "or H 2. We finish the stage of the removal by mirroring (reverse) the same side face, restoring the original position of the affected edge cube of the upper layer. After that, we perform operation a) or b) of the first stage. In case a) the cube came to the front face so that the color of its front face matches the color of the facade. In case b) the cube must not only be moved up, but also unfolded so that it is correctly oriented, standing in its place.

   We collect the cross of the upper line

2. The required corner cube is found (having the colors of the faces F, V, L) and, using the same technique that is described for the first stage, it is displayed in the left corner of the selected facade face (or yellow). There can be three cases of orientation of this cube. We compare our case with the picture and apply one of the operations of the second stage a, beat c. The dots on the diagram mark the place where the desired cube should be placed. We look for the remaining three corner cubes on the cube and repeat the described technique to move them to their places on the top face. Result: the top layer is picked up. The first two stages cause almost no difficulty for anyone: it is quite easy to follow your actions, since all attention is paid to one layer, and what is done in the remaining two is not at all important.

   Choosing the top layer

3. Our goal: to find the desired cube and first bring it down to the front face. If it is at the bottom - by simply turning the bottom face until it matches the color of the facade, and if it is in the middle layer, then you must first lower it down using any of the operations a) or b), and then match it in color with the color of the facade face and perform the operation of the third stage a) or b). Result: two layers collected. The formulas given here are mirror formulas in the full sense of the word. You can clearly see this if you put a mirror to the right or left of the cube (with an edge towards you) and do any of the formulas in the mirror: we will see the second formula. That is, operations with the front, bottom, top (not involved here), and back (also not involved) faces change sign to the opposite: it was clockwise, it became counterclockwise, and vice versa. And the left side changes from the right one, and, accordingly, changes the direction of rotation to the opposite.

   We find the desired cube and bring it down to the front face

4. The goal is achieved by operations that move the side cubes of one face, without ultimately violating the order in the collected layers. One of the processes that allows you to pick up all the side faces is shown in the figure. It also shows what happens in this case with other face cubes. By repeating the process, choosing a different front face, you can put all four cubes in place. Result: the rib pieces are in place, but two of them, or even all four, may be incorrectly oriented. Important: before proceeding with this formula, we look at which cubes are already in place - they may be incorrectly oriented. If there is none or one, then we try to rotate the upper face so that the two that are on two adjacent side faces (fv + pv, pv + tv, tv + lv, lv + fv) fall into place, after that we orient the cube like this , as shown in the figure, and execute the formula given at this stage. If it is not possible to combine the details belonging to adjacent faces by turning the top face, then we execute the formula for any position of the cubes of the top face once and try again by turning the top face to put 2 details located on two adjacent side faces in their places.

   It is important to check the orientation of the cubes at this stage

5. We take into account that the unfolded cube should be on the right side, in the figure it is marked with arrows (cube pv). Figures a, b, and c show possible cases of location of incorrectly oriented cubes (marked with dots). Using the formula in case a), we perform an intermediate rotation B "to bring the second cube to the right side, and a final rotation B, which will return the upper face to its original position, in case b) an intermediate rotation B 2 and the final one also B 2, and in case c) intermediate rotation B must be performed three times, after turning each cube and also completed with rotation B. Many are confused by the fact that after the first part of the process (PS N) 4, the desired cube unfolds as it should, but the order in the collected layers is violated. confuses and makes some people throw an almost completed cube halfway through. Having completed an intermediate turn, ignoring the “breakage” of the lower layers, we perform operations (PS N) 4 with the second cube (the second part of the process), and everything falls into place. Result: assembled cross.

   The result of this stage will be an assembled cross

6. We put the corners of the last face into place using an easy-to-remember 8-way process - forward, rearranging the three corner pieces in a clockwise direction, and reverse, rearranging the three dice in a counterclockwise direction. After the fifth stage, as a rule, at least one cube will sit in its place, even if it is incorrectly oriented. (If after the fifth stage none of the corner cubes has sat down in its place, then we apply any of the two processes for any three cubes, after that exactly one cube will be in its place.). Result: all the corner cubes are in place, but two of them (maybe four) may not be oriented correctly.

   Corner cubes sit in their places

7. We repeatedly repeat the sequence of turns PF "P" F. Rotate the cube so that the cube we want to unfold is in the upper right corner of the facade. An 8-way process (2 x 4 turns) will rotate it 1/3 turn clockwise. If at the same time the cube has not yet oriented, repeat the 8-move again (in the formula this is reflected by the index “N”). We do not pay attention to the fact that the lower layers will become a mess. The figure shows four cases of incorrectly oriented cubes (they are marked with dots). In case a) an intermediate turn B and a final B" are required, in case b) - an intermediate and final turn B 2, in case c) - turn B is performed after each cube is rotated to the correct orientation, and the final B 2, in case d) - intermediate rotation B is also performed after each cube is rotated to the correct orientation, and the final rotation in this case will also be rotation B. Result: the last face is assembled.

   Possible errors are shown with dots

Formulas for correcting the placement of cubes can be shown like this.

Formulas for Correcting Misaligned Cubes in the Last Step

The essence of Jessica Friedrich's method

There are several ways to assemble the puzzle, but one of the most memorable is the one developed by Jessica Friedrich, a professor at the University of Binghamton, New York, who develops techniques for hiding data in digital images. While still a teenager, Jessica became so fascinated with the cube that in 1982 she became the world champion in speed cubing and subsequently did not leave her hobby, developing formulas for quickly assembling the "magic cube". One of the most popular options for folding a cube is called CFOP - after the first letters of the four assembly steps.

Instruction:

1. We collect the cross on the upper face, which is made up of cubes on the edges of the lower face. This stage is called Cross - cross.
2. We collect the lower and middle layers, that is, the face on which the cross is located, and the intermediate layer, consisting of four side parts. The name of this step is F2L (First two layers) - the first two layers.
3. We collect the remaining face, not paying attention to the fact that not all the details are in place. The stage is called OLL (Orient the last layer), which translates to "last layer orientation".
4. The last level - PLL (Permute the last layer) - consists in the correct arrangement of the cubes of the upper layer.

Friedrich Method Video Instructions

The speedcubers liked the method proposed by Jessica Friedrich so much that the most advanced amateurs develop their own methods to speed up the assembly of each of the stages proposed by the author.

2 x 2

The 2 x 2 Rubik's Cube or mini Rubik's Cube is also stacked in layers, starting from the bottom level.

The mini-dice is a lighter version of the classic puzzle

Easy Assembly Instructions for Beginners

1. We assemble the bottom layer so that the colors of the last four cubes match, and the remaining two colors are the same as the colors of the neighboring parts.
2. Let's start organizing the top layer. Please note that at this stage the goal is not to match the colors, but to put the cubes in their places. We start by determining the color of the top. Everything is simple here: it will be the color that did not appear in the bottom layer. Rotate any of the top cubes so that it gets to the position where the three colors of the element intersect. Having fixed the corner, we arrange the elements of the remaining ones. We use two formulas for this: one for changing diagonal cubes, the other for neighboring ones.
3. We complete the top layer. We carry out all operations in pairs: we rotate one corner, and then the other, but in the opposite direction (for example, the first one is clockwise, the second is counterclockwise). You can work with three angles at once, but in this case there will be only one combination: either clockwise or counterclockwise. Between rotations of the corners, we rotate the upper face so that the corner being worked out is in the upper right corner. If we work with three corners, then we put the correctly oriented one at the back left.

Formulas for rotating angles:

• (VFPV P"V"F")² (5);
• V²F V²F "V"F V"F"(6);
• FVF² LFL² VLV² (7).

To rotate three corners at once:

• (FVPV "P" F "V")² (8);
• FV F "V FV² F" V² (9);
• V²L"V"L²F"L"F²V"F" (10).

Collecting the most difficult versions of the cube

These include toys with a number of parts from 4 x 4 and up to 17 x 17.

Models of a cube for many elements usually have rounded corners for ease of manipulation with a toy

Do you know which toy has earned the title of the most sold in the world? No, not the beauty of Barbie and not even Lego. The absolute leader in sales is considered to be a much more intelligent little thing - the Rubik's Cube. This year, the colorful puzzle of Hungarian origin is celebrating its 41st birthday. For four decades, millions have tried to conquer it. And today we will tell you how to solve a rubik's cube using only two moves and one little secret.

In 1980, a mailing list for fans of the Rubik's Cube opened. Since then, thousands of puzzle connoisseurs, including a staggering number of mathematicians, engineers and programmers, have joined forces to find "God's Algorithm": a way to solve a cube in the minimum number of moves. In July 2010, Palo Alto programmer Thomas Rockiki, Darmstadt math teacher Herbert Kotsemba, University of Kent mathematician Morley Davidson, and engineer at Google Inc. John Dethridge proved that each configuration of the Rubik's Cube can be solved in no more than 20 moves. BUT the current record is 4.94 seconds. Well, the method described below does not guarantee a speedy solution. But why not test the theory in practice?

Just rotate the left edge.

Now rotate the top face.

Repeat these two combinations one after the other. How many times? Until you collect!

Video demonstration This method has already collected more than 14 million views. Of course, there were many dissatisfied people in the comments who failed to solve the puzzle. Maybe they just didn't repeat the combo long enough?

Have you noticed how rapidly the edges of the cube “fly” in the hands of professionals? It turns out that there is a little trick here. To speed up the process, you need to use ... lubrication! Liquid silicone will do.

Rotate the sides of the cube to the position as shown in the photo.

I continue to update the schemes for solving puzzles. This time I found on one of the foreign sites rubiks.com quite a decent, well-illustrated instruction for the classic 3x3x3 Rubik's Cube. The assembly method is somewhat different from the method from the Science and Life magazine, but just as simple. Translated, added pictures from the original, in some places I added a couple of words from myself, I think it turned out well. Also here is a link to .

You can buy a classic Rubik's Cube 3x3x3 on ozon.ru

Stage 1. Get acquainted with your Rubik's cube.

The names of the parts of the Rubik's Cube:

Rib parts or ribs– parts with two colors. In total, the cube has 12 edge parts located in the middle of the edges.

Corner pieces or corners are parts with three colors. In total, the cube has 8 corner pieces located at the corners.

Central parts or simply centers– parts with one color. In total, the cube has 6 central parts located in the center of each face. The central parts do not move and represent the colors of their faces.

Centers always opposite each other:

• White is the opposite of yellow.
• Orange is the opposite of red.
• Green is the opposite of blue.

Each side of the cube is denoted by a Latin letter

R- right side - the right side of the cube L- left side - left side of the cube

U- top face - the top side of the cube

D- lower face - the lower side of the cube

F- front face - the front side of the cube

B- back face - back side of the cube Comment: the letter "i" after the letter of the face means backward movement or counter-clockwise movement when looking directly at the face.

Very important

When performing the movements below, keep the cube fully turned with one side towards you, as shown in the figure. The dark gray color in the pictures means that the actual color of these parts does not matter. Every movement is one fourth of a full turn 360 degrees.

Stage 2. Assemble the white cross.

A task: Holding your die so that the white center is on the top face (U), you must complete the white cross as shown in the picture below. Most of this stage is achieved by trial and error, but there are still a few tips.

Hints:

Be sure to remember that you need to collect the parts of the white cross in the following order - blue, orange, green, red.

Notice how the edges in the image above blend in with the top white center and the side red or blue center. This way you can easily determine that the edges are in the right places.

Keeping the white center position on the top face, move the white/blue edge to the bottom face (D). Next, rotate the bottom face until the white/blue edge is directly under the blue center. Now take the die so that the blue center and white/blue edge are on the right side (R).

Rotate the right side (R), until the blue/white edge is on the top(U) face above the blue center.

If your die looks like the one below, then take the die so that the orange center is on the right side, and assemble the side with the orange center in the same way.

If your die looks like the one below, then follow the sequence below, making sure the blue center is on the right (R) side.

In the same way, the remaining parts of the white cross are assembled.

Congratulations!

If your die has a white cross the same as in the picture, then you can go to stage 3!

Stage 3. We collect white corners.

A task: take the die so that the white cross is on the top face (U). Now you have to collect the white corners, and get a cube like in the picture below.

Hints:

The corners will have one white edge and 2 other color edges.

If the corner is already on the bottom face, rotate the bottom face until the corner is directly below where it should be. After that, your cube may look like one of the 3 pictures below.

Then repeat the sequence below 1, 2, or 3 times, or until the corner is in place and correctly oriented.

Repeat the whole process for all four corners.

If the corner is located on the top face, then move it to the bottom face by following the sequence:

Now rotate the bottom face until the corner is directly under its location on the top face.

Congratulations!

If your white layer looks like the picture below, then you have completed one third of the cube and you can proceed to stage 4.

Stage 4. We collect the middle layer.

A task: Take the cube so that the fully assembled white layer is on the bottom face. Now you need to assemble the middle layer by placing the side edges in their places.

Hints:

Pay attention to the vertical blue stripe (it can also be red, orange, green) - this is critical.

Assemble this vertical stripe by rotating the top face until the color of the edge on the top face without yellow matches the color of the center of the face. The color of the top part of the edge on the top face determines the direction of movement of the edge, that is, in which direction this part should move.

1) If you move the edge in the same direction as in the picture, then follow the sequence of pictures below.

2) If you move the edge in the same direction as in the picture, then follow the sequence of pictures below.

Repeat these steps until all side edges are in place.

Comment: if one of the edges is already in place, but not properly oriented, follow one of the sequences above and it will be in the top layer. After that, follow the appropriate sequence of actions to place the edge back into place in the middle layer.

Congratulations!

If the bottom two layers on your cube look the same as the picture below, you can proceed to stage 5. You have passed two-thirds of the way!

Stage 5. We collect the top layer. We get a yellow cross.

A task: compare the state of the yellow face of your die with the patterns below. Then follow the appropriate sequence.

Clue: the yellow parts on the top face should not yet match the color of the side faces.

Step one: Collect the yellow cross.

Switch to step two and start collecting the corners of the yellow face.

Perform the following sequence of actions:

Option 3.

Option 4.

Step Two: Make all corners of the top face yellow.

Take a look at the top face and match the state of the die with the options below.

If there are no yellow corners on the top yellow side, then you must take the die so that the yellow side of one of the corners is on the left side of the die. See drawing.

If there is one corner on the yellow face, follow the sequence below.

Option 3. If there is not a single yellow corner on the upper yellow face, and there is also not a single corner that could be used in option 1(that is, all corners have faces on the right). Then take the cube as shown in the picture below. The yellow part of the corner should be on the front face of the cube.

Follow the sequence below 1, 2 or 3 times to get a fully assembled yellow face. After each execution of the sequence, re-compare the state of your die with the options described above.

Congratulations!

If your cube looks like the one in the picture, you can go to stage 6!

Stage 6. We put the yellow corners in their places.

A task: Holding the cube as shown in the figure, rotate the top face until at least 2 corners are in place. These 2 corners should be on places A,B or A, D or B, C as shown in the figure below.

If all four corners are in place, then go to step 2.

Step 1. We put the yellow corners in their places.

Holding your die as described above, look at the top face. Place two right corners on the back face at positions A, B or diagonally A, D or B, C.

If corners are in place A and B, then swap corners C and D by following the sequence below.

If you need to swap diagonal corners B and C, or D and A, then do the sequence once. Then, rotate the whole cube so that the two correct corners are on the back face, and repeat the sequence.

Congratulations!

If your cube looks like the one in the picture, then you can proceed to step 2.

Step 2. Place the yellow edges correctly.

If one edge is in place and three are not, then take the whole cube so that the correct edge is on the back face. Next, determine in which direction to move the remaining edges: clockwise or counterclockwise. Depending on the direction of travel, follow one of the sequences below.

If all four edges are out of place, run any of the sequences once. After that, one of the edges will be in its place. Then go to the beginning of step 2 and repeat the procedure.

To move E F G or EFGH clockwise

To move EFG or EFGH counterclockwise.

Congratulations, you have completed the cube!

Surely everyone has known since childhood the famous puzzle, named after its creator - Erno Rubik. Pretty quickly, she gained popularity and reached the most remote corners of the planet.

Without proper skill, it will not work to put together a puzzle, even after doing a hundred manipulations, but relatively recently, specialists from Inc. learned how to solve a rubik's cube in 20 moves. They managed to achieve this phenomenal result with the help of a computer, which was given the task of analyzing all possible combinations.

Where did the Rubik's Cube come from?

Back in 1974, the Hungarian architect and teacher at the Academy of Applied Arts Erno Rubik thought about the best way to learn

He wanted a new invention to help students explore the world, and one day he had a sensational idea - to create a puzzle. The task, it would seem, is elementary - to rotate the rows of the cube until each of the sides becomes the same color. But the scheme for assembling a Rubik's Cube is not so simple and can take even several hours in time, without giving a result. The students appreciated and got carried away with the new toy. At that moment, the creator did not even suspect that after many years scientists would puzzle over solving the puzzle until they figured out how to solve a Rubik's cube in 20 moves.

How did the worldwide popularity come

At first, the original toy was not popular with investors. It was believed that its production would not be profitable, since the assembly of the Rubik's cube could only be of interest to intellectuals. Nevertheless, one small company decided to invest in this unusual project, and the puzzle began to conquer Budapest.

A few years later, Tibor Lakzi, an intermediary of one of the German firms, arrived in the city and became interested in the original puzzle, which at that time was very popular among the townspeople. Realizing that the distribution of an amazing invention around the world could bring huge profits, he decided to promote the Rubik's Cube. For novice businessmen Lakzi and Rubik, the main difficulty was the search for investors. But thanks to Tibor's economic education and his commercial flair, the owner of Seven Towns Ltd, Tom Kremer, was soon involved in the project. He undertook large-scale production and distribution, which helped the cube become popular all over the world.

"God's Algorithm"

Since 1982, competitions have been regularly held in many countries, in which the main task of the participants is the speed assembly of the Rubik's Cube. In order to solve the puzzle as quickly as possible, it is not enough just to have good dexterity and ingenuity. A person should know the optimal scheme for assembling the Rubik's cube, which allows you to expend as little effort as possible. The minimum number of steps required to solve the problem is the "God's Algorithm".

Many learned minds and simple amateurs have tried to find a solution. At one time it was believed that minimum number steps from any position - 18, but later this theory was refuted. Many years have been spent searching for the optimal sequence, and only in 2010, scientists managed to find out how to solve a Rubik's cube in 20 moves, regardless of the position of the puzzle before the assembly began. This is currently an absolute record.

Who is faster - a car or a person?

On the this moment Colin Burns, an American schoolboy, is the fastest person ever to solve a puzzle in less than 5.5 seconds. And the robot, assembled by British engineers from parts of the EV3 designer, coped with this task in 3.253 seconds. The advantage of the mechanism is not only that the work of all its parts is more coordinated than the actions of a person. Scientists gave him as many as 4 hands, which allow you to perform all operations 2 times faster.

How to learn to collect it

There is more than one standard Rubik's cube scheme that allows you to learn how to solve this original puzzle in a short time. Different build systems allow you to approach the issue in different ways. Which one to choose is up to you. Of course, it is unlikely that without the computer power of Google you will learn how to solve a Rubik's cube in 20 moves, but you will learn how to find simple solutions in a short time. The main thing is that you have enough perseverance. No technique will help solve the puzzle without problems if you are not ready to spend your precious time learning.

But you should not give all your time to this toy. Doctors have noted an increase in the number of patients in psychiatric clinics after the appearance of the Rubik's Cube. And traumatologists began to regularly encounter symptoms, later called "Rubik's syndrome." It appears as sharp

Assembly diagram

There are several schemes that allow beginners to quickly learn how to add a Rubik's cube. Attached to this article is one of them:

1. First you need to assemble a cross, the ends of which are continued on adjacent faces. There is no universal technique - everything comes with practice.
2. Next, you need to complete the entire side on which the cross was assembled, and assemble the belt from the parts around it. It is important to ensure that each belt is the same color.
3. Now you need to collect the second belt and go to the opposite side of the cube.
4. We collect the cross on this side in the same way as at the very beginning.
5. We complete the whole side.
6. Now we put the corners of the cube in order - we make the colors on them match the colors of the sides to which they are turned.
7. It remains only to correctly rotate the parts that have only 2 sides. The cube is assembled.

Now you can learn how to solve one of the most popular puzzles in the world. The universal Rubik's cube scheme will help you with this.
