Complete instructions for solving a 3x3 Rubik's Cube. How to solve a Rubik's Cube. Branded video instruction from Rubik's - Games Lab. In Russian-language guides for assembling the Rubik's Cube, initial letters from Russian names are used

In 1975, sculptor Erne Rubik patented his invention called the "Magic Cube". For more than 40 years, all rights to the puzzle have belonged to the company of a close friend of the inventor - Tom Kroener - called Seven Towns Ltd. The English firm controls the production and sale of the cube around the world. In Hungary, Germany, Portugal and retained its original name, in other countries the toy is called the Rubik's Cube.

Puzzle Varieties

The classic Rubik's Cube is 3 by 3 squares. Over time, they came up with a huge number of shapes and sizes for toys. No one can surprise anyone with a puzzle in the form of a pyramid or a 17x17 cube. However, humanity never rests on its laurels.

Obviously, there is no assembly scheme for beginners of this cube. The process of assembling and solving the puzzle can take years. IN Lately interest in the cube is growing not only in Asia and Europe, but also where the toy was not very popular, for example, in the USA. One of the fans of the Rubik's Cube filmed the assembly of the 17 by 17 puzzle. The total length of the video is 7.5 hours, the shooting was carried out during the week.

Growing demand creates supply. Sometimes the models for sale are incredible and it is not always clear how they will look when assembled. Each country has its favorite varieties of toys.

What is speedcubing?

Fans of the game arrange real competitions in the speed of building a cube. On sale there are special "high-speed" puzzles. The mechanism of rotation of such Rubik's cubes is very high quality, and the turns of faces and rows can be done with the movement of one finger.

World Cube Association (WCA) is non-profit organization supporting the speedcubing movement. The WCA regularly organizes competitions around the world. Almost all countries have representatives of the organization. Anyone can become a participant in a speedcubing event, you just need to register on the site and meet the assembly standard. The most popular discipline in such competitions is the speed assembly of the Rubik's Cube 3x3. The standard for participation is 3 minutes, but even if a person cannot solve the problem in the allotted time, he will still be allowed to the event. You can sign up for any discipline, but you need to come with your own puzzle.

The record for solving a 3x3 Rubik's Cube belongs to the robot Sub1, created by engineer Albert Beer. A machine is able to solve a puzzle in a fraction of a second, while a human takes 4.7 seconds to do it (an achievement by Mats Valk in 2016). As you can see, the participants in the speedcubing movement have someone to look up to.

What are the algorithms for solving a 3x3 Rubik's Cube?

There are many ways to solve the famous puzzle. Variants of 3x3 Rubik's cube assembling schemes have been developed for both beginners and advanced people with complicated schemes: 4x4, 6x6 and even 17x17.

The 3x3 puzzle variant is considered a favorite classic by most fans. Therefore, there are much more instructions on how to solve a 3x3 Rubik's Cube than any other.

What should the puzzle look like?

You can assemble a toy according to the scheme only from a pre-prepared position. If the patterns on the faces of the cube are located incorrectly, then it will not be possible to solve it using the 3x3 Rubik's cube assembly algorithm for beginners. There is a set of such positions for different solutions.

The picture shows or just a "cross" - the starting point of the easiest way to solve a 3x3 Rubik's Cube. It is recommended to disassemble and fold the toy correctly.

Designations of schemes and methods of rotation of the cube

Before proceeding with the disassembly of the Rubik's 3x3 cube formulas, it is worth learning the notation used in speedcubing. All puzzle movements are indicated capital letters. The absence of an apostrophe above the symbol means that the rotation is clockwise, if there is a sign, then the rotation should be in the opposite direction.

The first letters of English (or Russian) words denoting movements are considered generally accepted:

• front - F or Ф - rotation of the front side;
• back - B or T - rotation of the back side;
• left - L or L - rotation of the left row;
• right - R or P - rotation of the right row;
• up - U or B - rotation of the top row;
• down -D or H - rotation of the bottom row.

Pointers can also be used to change the position of the cube in space - interception movements. Here, too, everything is simple, from the school course of geometry, everyone knows the coordinate axes X, Y and Z. The movement of X means that the cube must be rotated by the face F to the place of the face U, when shifting Y - F, it should take place L, and when rotating Z - F moves to R.

The following group of symbols is rarely used, it is used when drawing up patterns of patterns:

• M - turn of the middle row, between the right (R / R) and the left (L / L);
• S - rotation of the middle row, between the front (F / F) and the rear (B / T);
• E - turn of the middle row, between the top (U / B) and the bottom (D / H).

Why collect patterns on the faces of the cube?

At speedcubing meetings, they compete not only in solving a puzzle, but also in the ability to make various patterns on a 3x3 Rubik's cube. They do this in order to quickly and easily collect the cube in the desired position.

There are a huge number of schemes for assembling a variety of patterns: "dots", "chess", "dots with chess", "zigzag", "meson", "cube in a cube in a cube" and many others. Only for the classic puzzle there are more than 46 of them. Speedcubing masters consider it shameful to disassemble the toy. Also, making patterns on a 3x3 Rubik's Cube is a great way to practice and improve skills.

The figure shows variants of various puzzle patterns. The following are a few more formulas for assembling the most interesting drawings from the position of the cross:

• chess - M 2 E 2 S 2;
• zigzag - (PLFT) 3;
• four z - (PLFT) 3 B 2 H 2;
• Plummer's cross - TF 2 N "P 2 FNT" FN "VF" N "L 2 FN 2 V";
• cube in a cube in a cube - V "L 2 F 2 N" L "NV 2 PV" P "V 2 P 2 PF" L "VP".

3x3 Rubik's Cube Algorithm for Beginners

Although there are many ways to solve the puzzle, simple and clear schemes for beginners are not so easy to find. With each completed assembly step, the Rubik's 3x3 cube formulas become more difficult. It is necessary not only to change the pattern correctly, but also to save what has been done before. Below is one of the options for how to easily solve a 3x3 Rubik's Cube.

Conventionally, the whole process can be divided into the following stages:

1. Assembly of the cross in the upper face of the cube.
2. The correct composition of the entire upper face.
3. Work on the middle layers.
4. Correct assembly of the ribs of the last row.
5. Assembling the cross of the lower face.
6. Correct orientation of the corners of the last face of the cube.

Solving the puzzle - preparatory work

The first stage is the easiest. Beginners can try their hand and practice making cube patterns according to the available instructions, but this process will take a long time.

You need to select the top face and the color that will be collected first. The 3x3 Rubik's cube assembly algorithm for beginners was developed from the "cross" position. It is not difficult to make it, you need to select the central color, find 4 edge elements of the same shade and raise them to the selected face. The colored arrow in the picture indicates the desired part. The options for the location of the desired element may be different, depending on this, 2 sequences of actions A and B are described. The difficulty lies in continuing the cross along the sides of the cube. You can take a closer look at the final view of the stage in the image posted above.

Solving the puzzle - working on the middle row

At this stage of the 3x3 Rubik's cube assembly scheme for beginners, you need to find and assemble the corner elements of the upper face. The end result should be the complete solution of the cross face and the top row of the puzzle.

The image shows three cases of a possible facet pattern. Choosing one of the methods A, B or C, you need to collect all 4 corners of the cube. By memorizing rotation algorithms and practicing them, the skills and mastery of assembling a puzzle are acquired. It is pointless to consider formulas and represent the process, it is much easier to take a cube and try all the methods in practice.

The third stage seems simple, but it is only an appearance. To solve it, two situations of patterns are described and, accordingly, two rotation formulas are compiled. When applying them, it is worth remembering to preserve the previously achieved results. Masters constantly keep in memory the last 3-4 rotations, so that in case of failure, return the cube to its original state.

To solve the puzzle, you need to rotate it along the coordinate axis in search of the necessary elements and work with them. Such movements are rarely displayed in formulas, only in special cases. It is recommended to start assembling the edge faces from the elements of the lower rows, after such rotations all the necessary cubes will descend from the middle to the lower row.

Solving the puzzle - drawing up the second cross

At the fourth stage, the toy is turned upside down. Solving the last face is the most difficult part of the 3x3 Rubik's cube algorithm for beginners. The rotation formulas are long and complex, and their execution will require special care. The purpose of the action is to place the rib elements in their places for further drawing up the cross. The orientation of the rib portions may be incorrect. There is only one formula for the movement of the cube and it should be applied until the goal of the stage is reached.

The rotations of the fifth stage are aimed at turning the elements to the correct side. Its peculiarity lies in the fact that the same rotation formula is used for all three patterns in the figure, the difference is only in the orientation of the cube itself.

The formulas for the movements of the 5th stage are as follows:

• (PS N) 4 V (PS N) 4 V" - option "A";
• (PS N) 4 V" (PS N) 4 V - option "B";
• (PS N) 4 V 2 (PS N) 4 V 2 - option "B".

C H is the rotation of the middle row clockwise, and the exponent above the bracket is the number of repetitions of actions in brackets.

Puzzle Solving - Last Spins

At the sixth stage, as well as at the fourth, the necessary cubes are placed in their places, regardless of their orientation. The puzzle should be rotated so that the element that is already in the right place is located in the far left corner at the top of the cube. The options proposed to solve the formula mirror each other. It is necessary to repeat rotations until the desired result is achieved.

The seventh stage is the most solemn and most difficult. When rotating the cube, violations in already assembled rows are inevitable. You will need to fully focus on the movements, otherwise the result of the assembly may be irretrievably ruined. As in the fifth stage, there is only one sequence of movements, but it is repeated 4 times. First, rotations are performed to orient the element, then reverse rotations are performed to restore broken rows.

Don't forget to record movements with signs. English alphabet. The formulas for the movements of the faces and rows of the cube at this stage are as follows:

• (RF "R" F) 2 U (RF "R" F) 2 - option "a";
• (RF "R" F) 2 U "(RF" R "F) 2 - option "b";
• (RF "R" F) 2 U 2 (RF "R" F) 2 - option "c".

B is a 90 degree rotation of the top face, B" is a counterclockwise rotation of the same face, and B2 is a double rotation.

The complexity of the stage is in the correct assessment of the location of the elements and the choice of the required rotation option. It can be difficult for beginners to immediately correctly identify the pattern and match it with the correct formula.

Rubik's Cube and children

A tricky puzzle is interesting not only for adults, but also for children. Teenagers became the world record holders for solving the Rubik's Cube. In 2015, Colin Burns, who was only 15 years old at the time, assembled the toy in 5.2 seconds.

A simple but fascinating toy has continued to interest the younger generation for the past 5 decades. Children's hobby often develops into a profession. There are mathematical methods for evaluating the solution to Rubik's cube problems. This section of mathematics is used in compiling and writing solution algorithms for automated computers. Robots that really look for ways to solve the cube, and do not follow a pre-driven movement algorithm, solve the puzzle in 3 seconds, for example, CubeStormer 3.

How to forget about incomprehensible schemes and solve the Rubik's cube according to the scheme for beginners?

If you still can't solve the puzzle without getting frustrated: in our article you will find the answer.

Now we will try to explain in detail how to do this in order to surprise ourselves, friends and relatives.

What is a Rubik's Cube?

If you have set yourself a task, then after reading the article it will become easy.

But if you do not know how this most mysterious cube works, what it consists of and how it functions, the task becomes much more complicated.

You will learn how to solve the Rubik's cube according to the scheme for beginners in Russian below, but remember that you should not underestimate the complexity of the presented.

A regular 3x3 rubik is a small mechanical 3D cube, the sides of which are painted in different colors.

Collecting the Rubik's Cube

Let's take a look at the particles of the cube.

Let's start with the central element, it is one on each side. It can be rotated around its axis, but always each of them remains in place in the "correct" position.

There are a little more corner elements - 8, and they have three different colors.

We must not forget about 12 edges with several different colors located between the corners.

It turns out only 20 particles that can be moved, and the solution of the problem depends entirely on knowing the correct change in their position.

If you start to rotate one side, you can see the central elements, or rather, how they do not move. The edge becomes where it should be, and the corner - in its place.

Tip: each of the elements has a specific type, it cannot be changed after rotation.

Puzzle Solving Basics

If you want to know how to solve a Rubik's cube, we have a special diagram for beginners in Russian.

Put yourself - let the elements fall into place. Focus on the center, only the cubes do not change their position there.

For example, the edge between red and green is red-green.

Take as a guide the rule: there must be an edge of the same color near the green.

Scheme 1. Correctly arranged particles are depicted in blue, those that can be changed in green, and the action is performed on yellow

The corner must not be overlooked, it is always tricolor and is placed between the central elements of the colors that correspond to it.

How to solve a Rubik's cube - a step-by-step diagram for beginners in pictures

It is necessary to collect the edges of one side. First, choose a color that will be the first. Let it be yellow. So, let's begin!

turn the cube yellow up, so the bottom will remain white, in almost all existing models this markup is presented.

Tip: if you are interested in how to solve a Rubik's Cube, use the 3 by 3 diagram for beginners in Russian. You need to fold a cross at the top, for this, put the edges of your chosen color in position. They will match the central element.

Using our advice, remember what needs to be done in order.

The second edge color should match the center particle that is closest. Practice and you will succeed.

The main thing - do not stop, try and move forward with confidence. Patience will come to your aid and again patience, do not give up.

Assemble the cross according to the scheme, but do not forget that this will need to be done 4 times - for each side.

1. The cube should be in your hands, turn it over, there should be a yellow center element on top, or the color that you picked up, at the bottom - white
2. See if there is yellow at the bottom and note both edge colors
3. In the event that you found a yellow square, twist the cube until the edge takes its place on top
4. Continue to follow the instructions on how to solve the Rubik's Cube according to the scheme for beginners in Russian in the photo and do one of the actions: the center is at the bottom, in front, the edge is in the intermediate layer and repeat step number 1

Tip: If you see a yellow color on top, but it's out of place or oriented incorrectly relative to the center, change its position by simply putting another particle in its place.

The edge will stand in the position described earlier, with the help of the scheme, it will fall into place.

This must be done for each of the yellow cubes, in the end you get a cross.

Top face

After you have folded the cross, you can begin to assemble the top completely. You need to put the corners in place.

If you put them the way you want, nothing will work - everyone has their own place. This is determined by the colors of which it consists.

Do not forget that any actions performed will need to be repeated 4 times for all corners.

1. Put the cube in its original position, as in the previous time
2. Try to find in the lower layer the corner where the yellow square will be, stop your attention on a few colors on it
3. Turn the bottom, the corner should be under its place
4. You can choose from several solutions: yellow left, right and bottom

We move on to the next face, while not forgetting about the central elements. They are fixed in place, so you need to swap them and think about how best to place them.

All actions are repeated, as before, 4 times.

1. This time you need to take the cube with a white layer up, at the bottom you get a yellow one, already assembled.
2. Find in the top layer the edges without white color at both sides.
3. Scroll up this way until the edge and center colors are exactly the same, it looks a lot like an inverted T.
4. Choose one of the examples provided, your decision should depend on whether the edge is placed on the left or on the right. Here are the options to choose from: edge moved to the right or edge moved to the left.

If you can't find elements in the layer without white on either side, it means they're in the middle.

To correct this situation, rotate the other edge from the top layer into place. You can continue your work by following the instructions.

Collecting the second cross

Now that the 2 layers of the cube are already assembled, let's try to make the 4 outer elements of the top white.

You need to focus exclusively on the edge particles, bypassing the corners.

Still don't know how to solve the Rubik's cube according to the scheme for beginners in Russian? Thematic video will come to your aid.

So, if the first 4 white edges are already on top, move on to the next step.

But if there are only a few, use the instructions below and pay attention to how they are located relative to each other.

It all depends on whether they are next to each other or opposite: adjacent edges, opposite edges are white, not a single snow-white square stands correctly.

If you try to fold the cross in one of the ways described above, then if there is not a single light square at the top, the result: 2 finished squares.

Depending on the combination received, choose your option of action, it can be the first or second plus the 4th step.

The second cross is ready. To match the sides color scheme with the center, repeat the steps of the fifth section.

Rotate the top of the cube until the two edges match in color with the center. The second cross is in place.

Corner Placement

The particles have already found their place, and you already almost completely know how to solve the Rubik's Cube according to the scheme for beginners in Russian from the video, it remains only to complete the corners.

This should be done regardless of their orientation, you should know when to get into position.

Tip: The corner is right when the close center pieces match the color scheme of the 3 pieces.

We will show you in which situations the corners are wrong and correct for assembly.

Of course, it may also happen that 4 corners fall into place initially.

If 1 fell into place, follow one of the examples:

1. Turn the edge forward, up to the right, the other edge - forward, again sideways, but left, down, right, the other edge - down, and the opposite - to the left
2. Left - up, right - left, forward, right, left - down, right - left, down, right

So, together we have assembled a 3x3 cube, if you are interested in how to solve a Rubik's cube, there is a special scheme for beginners in Russian and for a 2x2 cube.

I would like to believe that we were able to help you, and you have collected the Rubik's Cube.

This is quite an exciting activity that will help your mental abilities and motor skills of your fingers.

How wonderful this moment is when you manage to do what is sometimes beyond the power of the majority, and in this case we are talking about the fact that not everyone can quickly solve a Rubik's Cube. Although it is within the power of anyone who wants it. To do this, the main thing is to know a few secrets and acquire patience.

How to learn how to solve a rubik's cube - the secrets of success

5.66 seconds. That's how much time it takes Felix Zemdegs, the first person in the world who can quickly assemble this creation of the 1980s. After weeks of training, a beginner will be able to personally create an assembly record for himself for 2-3 minutes.

Considering the question of how to assemble a Rubik's Cube, it should be noted that before starting the lesson, it is necessary to "undress" the cube into parts. After all, it is possible that the manufacturer made an erroneous assembly, and this is fraught with a waste of time on assembling the toy.

Then comes the process of carefully memorizing the colors (which one is located next to which).

How to fully solve the Rubik's Cube - detailed instructions

Well, now let's move on to the main stages of putting together all the colors of the Rubik's cube.

We divide the cube into separate components:

• there are 8 corners, 12 edges, and 6 centers;
• each face includes 9 subfacets: a - lower, b - upper, c - left, d - frontal, e - right.

Please note that in the following, counterclockwise turns will be marked with an asterisk (*). If you meet a designation like a3, b3 - says that so many times (in this case three times) the face should be rotated 180 degrees.

The main goal for stage number 1: to collect the red color in one line. Next, we install 4 elements, thereby forming a cross.

So, the first layer is assembled together.

Further, it is recommended to find a rib that can be easily deployed by turning the top. So, when assembling a new layer, the red should not be touched. It should be kept face down. It is necessary to scroll the top layer (the one that is going to this moment) until the central sections of the cube coincide.

In order, as indicated in the photo, to put the white-blue part in place, use the following: b e b * e * b * d * b d.

To fill in the left side: b* c b c* b d b* d*.

A cross is formed from a certain color.

Now let's deal with the edges of the remaining layer. If it turns out that those cubes that match in are on different faces, you need to scroll the cube according to the formula: e b e* b e a2 e*.

If the matching elements are on adjacent faces, then: the unassembled part is in front of you, and the second one is the same on the left. e b e* b e b2 e*.

Now we will talk about the arrangement of the corners of the remaining layer. If the desired color is on the right (blue-white-orange in the photo), then: a e a* e* a e a* e*. The corner that needs to be collected should be brought to the bottom.

Surely each of us knows the Erno Rubik's Cube, or as it is customary to call it in the common people "Rubik's Cube". Oh, how much nerves and time we spent trying to figure out how to collect this tricky cube in order to get all sides of the same color. It turns out that there are whole schemes for collecting this "beast", about which we will now tell you.

Before proceeding with the assembly of the cube, it is necessary to understand what elements it consists of. Like all brilliant things, the cube is simple. The most popular 3x3 cube among ordinary people, consisting of 12 edges, 6 centers and 8 corners. Inside the cube there is a cross, thanks to which the faces of the cube move. The crosspiece is not movable and does not take part in the assembly.

Each center of the cube is painted in a certain color, and it indicates what color the side will be in the assembled state. The cube centers are not movable and they do not change their position in the process of assembling all the elements.
Edges are always painted in 2 colors. This is a solid element and cannot be broken when rotating the faces.
The corners of the cube are painted in three colors, which also do not separate during rotation.

This is how all 3x3 cubes are arranged and it doesn’t matter if it is fast or bought on the market in the nearest tent.

3x3 Rubik's cube assembly scheme for children, step by step instructions for beginners (the easiest way)

To understand the formulas that are used to assemble a cube, it is necessary to become familiar with the language of rotations. These special designations of the movements of the faces of the cube, with the help of which this or that assembly algorithm is written, will help you achieve heights in the assembly of the cube.

There are also designations for changes in the position of the cube in space, they are called intercepts.

If only the letter (R) is indicated in the prescribed algorithm, then the position of the cube changes clockwise. If the designation contains a letter paired with an apostrophe (R '), then the side changes counterclockwise. If there is a number after the letter, then this means that the side needs to be rotated the same number of times.

Initially, it is worth assembling the correct cross. Choose any center color and start assembling.

If the color of the center and rib stickers match, you have assembled the correct cross.

Put the center up, in our case it is white. We find 4 edges of the same color, select any of them and put it first. If the edge is in the middle layer, then with the movements L 'or R we put them to the white layer. Below are different situations and their solutions.

Thus, you will get a cross. Most often at this stage it will not turn out right, so you need to swap the edges. Twist the top layer until the 2 edges match in color with the centers. At this stage, you may find yourself in one of two situations (shown in the picture).

The R U R 'U' algorithm is also called bang-bang.

Now you need to fold the first layer. To do this, find a white corner (you will have a corner of the color that you chose in the first step), find a place on the bottom layer where it should be, put the corner in its place. The picture below shows three typical situations that you may have. After completing the algorithm from the picture, you can put the corner in its place.

We find 4 edges (with the exception of yellow). On the top layer, select the one you want to put first, then twist the top face until the center color matches the label of this edge. Next you will get one of the situations.

We collect the yellow cross. Please note that sometimes when carrying out the manipulations above, the yellow cross can turn out by itself. If this does not happen, find your situation and the algorithm for solving it in the picture below.

Next, collect the entire yellow side. After collecting the yellow cross, one of the 7 situations described below may appear. Find yours, and make flips according to the specified algorithm.

We collect the corners of the upper layer. Select any of the corners and use U, U2 and U’ to put it in place so that both corners match the color of the bottom layers. Take the white cube towards you and do one of the indicated algorithms.

At this stage, some difficulties may arise:

• corner fell into place along with another corner. Rotate the top face of the cube so that it stands up as in the above algorithm;
• corner fell into place along with another corner diagonally. The output is exactly the same as above.

It remains only to put the ribs in their places. Consider in the picture what situation happened to you and, following the algorithm, collect the edges.

Voila! The cube is assembled.

How to solve a Rubik's Cube in 20 moves, diagram?

For more than 40 years of the existence of the cube, a considerable number of schemes have been invented. most digestible and simple method considered to be a layered assembly. It consists of seven stages, which are depicted and painted in the schemes submitted by us. You may have to spend more time collecting for the first time than you thought. However, you can solve this puzzle by yourself or with your child.

To begin with, you must understand that when collecting a cube for the first time, you will not be able to achieve speed in a matter of seconds. In assembly, the main thing is to understand how the faces move correctly in the plane and learn how to determine their location. The simplest way, which should be used in the first couple, for children and adults, begins with the assembly of the cross on the upper edge.

The principle of the assembly method from the initial cross is simple. To do this, you need to study the instructions presented by us and the location of the faces.

At the sixth stage, it is necessary to send the corner cubes of the third layer to their places.

At the final stage 7, you need to deploy the corner cubes of the third layer.

Rubik's cube assembly scheme 3x3 in 15 moves

Already 7 years after the invention of the Rubik's Cube, competitions for its high-speed assembly began to take place. Fans of this puzzle began to develop algorithms and strategies that will allow you to assemble the cube in the minimum amount of time and moves. To date, there is only one algorithm for assembling a cube in the minimum number of moves and it is called the "Algorithm of God". Accordingly, it is impossible to collect a cube in 15 moves.

How to quickly solve a Rubik's cube 3x3 quick assembly scheme?

Building a cube takes a long time. Beginners in this business often wonder how to quickly assemble a cube and not waste time learning formulas. The whole process of quick assembly begins with the assembly of the lower cross. Further, according to the scheme that we posted below, collect the cube.

Maxim Chechnev, how to solve a Rubik's cube?

On the net you will find a huge number of manuals on the techniques for collecting the simplest Rubik's Cube. The ways of learning on the World Wide Web are not much different from one another, but there is a catch - not all of them are understandable and accessible, especially to children. After rereading complex formulas, the child is unlikely to understand anything and will be able to assemble his first puzzle on his own.

A simple and affordable way of learning was invented by Maxim Chechnev. The fact that his training scheme works for kids, he was convinced by working in children's camps and teaching children there different ages collect a rubik's cube.

The learning and assembly process will take your child several hours. Below will be presented video materials consisting of 9 lessons. It is always easier for children, and even adults, to understand how the assembly takes place using a good example, rather than trying to disassemble already complex formulas. In the final, the children will not only assemble this puzzle on their own, but will also remember all the stages of its assembly.

Jessica Friedrich, how to solve a Rubik's Cube?

Back in the 80s of the last century, another method for collecting a rubik's cube was invented by a Czech resident Jessica Friedrich. This method belongs to the layered and the cube is assembled, respectively, by layers. This technique was developed for beginners, but it has been improved. The thing is that Friedrich proposes to reduce the number of stages from 7 to 4. Initially, a side is selected and a cross is assembled on it, then the first and second layers are assembled simultaneously and only then the last layer, for which 2 stages were allocated. However, this method is by no means simple. Despite the reduction in stages, you will have to learn as many as 119 algorithms.

Experts do not recommend beginners to start learning how to assemble a cube. First, it is worth mastering the simplest layered technique, bringing your collection skills to at least 2 minutes, and only after that proceed to the Friedrich method.

Professional Rubik's Cube

You may be surprised, but in the world there are competitions for the speed of solving a cube and only aces take part in them. Cubes for speedcubing are chosen especially carefully.
