Collect the cube all sides. How to solve a rubik's cube in layers. Designations of schemes and methods of rotation of the cube

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.

There are many ways to solve a Rubik's Cube. 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 instructions, as well as a little 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.

Having understood all these conventions, 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 of how to solve a 3x3 Rubik's Cube: the easiest way, the diagram of which is right in front of you.








And, of course, the most understandable tool for assembling the cube will be a video lesson with a detailed description of an 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 faces. 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.

Numerous attempts to solve the Rubik's Cube failed? All the presented instructions on the Internet are written by professionals, but for the "dummies" the solution seems very confusing? Do you think that solving this puzzle is impossible? By following our step-by-step instructions, you will not only be able to fully assemble the most popular puzzle in the world without formulas, but also understand how you did it.

You will need:

Where to begin

So, your goal is to complete the Rubik's Cube. To do this without knowing how it works, what it consists of and how it functions, will not work.

The standard 3x3 Rubik's Cube is a mechanical 3D cube with each face painted a different color.

The traditional version is blue, green, white, yellow, red and orange. Edges:

In total, there are 20 movable elements in the Rubik's cube (12 edges and 8 corners) and the solution depends directly on knowing how they can change their position.

As we rotate one side, we see that the center pieces stay in place, the edge moves to where the edges should be, and the corner takes place in the corner.

It follows from this that each element has a certain type, which does not change after rotation (the edge remains the edge, the center remains the center).

Frequently Asked Questions

    What should be a Rubik's Cube?

    If you are not going to participate in competitions, you can take any cube. It is better for young people and children to buy a puzzle from Chinese manufacturers. When choosing, consider the following:
    - It is better to take the cube of the latest models, it provides for the shortcomings of previous versions, and it is more improved.
    - The right cube should spin easily, while cutting corners well.
    - Cubes for professionals can be disassembled and adjusted.

    How many edges does a rubik have?

    The classic Cube consists of 12 two-color side or edge elements (12 "ribs").

    How many rubik's cube puzzles?

    There are many ways to build a Cube. There are those that allow you to assemble a couple of formulas, but in a couple of hours. Others, by memorizing a couple of hundred formulas, allow you to solve a cube in 1 minute or even 20 seconds.

Basics

Our goal is to put all the elements in the right places. To determine the direction in which to rotate and the “correct place” of a particular square, you need to pay all your attention to the central elements, because, as we have already said, they have a fixed position.

For example, the edge that is located between the red and green center, respectively, is red-green, so you need to focus on placing an edge of the same color near the green center, and a red edge near the red central element.

The corner is always three-color, so care must be taken to place it between the center elements of the corresponding colors.

Step 1. Gathering the Edges of One Side

The first thing you need to do is choose a color to start with. In this example, the main color is yellow, it will be presented in all schemes. Everyone is free to choose the option that he likes best and start with it.

So, if the upper central element is yellow, then the bottom, respectively, is white (it is located on the opposite side in almost all models of the Rubik's cube).

In order to solve a 3x3 Rubik's Cube, you must first fold a cross on its upper face - put all the edges of the selected color (in our case, yellow) in the appropriate positions around the central element.

You need to do this in a certain order so that the second color of the edge matches the nearby center element.

This step is the hardest to explain to those who don't know how to solve a Rubik's Cube. This task is easier to solve on your own and you will undoubtedly succeed in doing it after a short training.

It is at this step that most beginners stop - they collect a cross, then one face - further, unfortunately, few people advance.

For those who cannot do this, below is a diagram of how to assemble the cross. Keep in mind you will have to repeat this step 4 times - one for each side.

  1. Take the Rubik's cube in your hands and turn it over so that the yellow center (or another color of your choice) is on top and white on the bottom.
  2. Look for yellow edges on the bottom plane. Pay attention to both colors of the rib.
  3. If you find a yellow edge on the bottom, rotate the layer until the edge with the yellow square is positioned under its "place" on the top edge.
  4. Perform one of the following actions:

a) Yellow "looks" down

b) Yellow looks ahead

c) Rib in the intermediate layer

Note: if the yellow square is on the top layer, but it is not properly positioned and oriented in relation to the nearby center, change its position by putting another element in its place.

After that, the edge will be in one of the three positions described above. Using the diagram, put it in the "correct" place. Repeat all the steps for each yellow edge and collect the cross on the top layer of the Rubik's cube.

Step 2. Assembling the top face

If you were able to fold the cross, then it is worth collecting the entire top layer, that is, putting the corners into place one by one. We cannot put them as we want, because each corner has a place specially reserved for it, which is determined by the colors of which it consists.

Just like in the previous step, there are several solutions that we will follow.

Remember that you will have to repeat all the steps 4 times - one for each corner.

  1. Flip the Rubik's Cube so that the yellow layer is on top and the white one is on the bottom.
  2. Look in the bottom layer for the corner with the yellow square. Note the 2 other colors on it.
  3. Twist the bottom layer so that the corner is under its "own" place.
  4. Use one of the solutions below:

a) yellow looks to the left

b) yellow looks to the right

c) yellow is on the bottom

note : if the yellow corner is not in the bottom layer of the Rubik's cube, then it means that it is in the top layer, but not in its place.

You need to put any corner from the bottom layer up (following the first solution, for example). This way you will get a yellow corner in the bottom layer.

Repeat for each corner until the top layer is complete.

Step 3. Algorithm for assembling the second face

We want to build the second layer of the cube. Remember that the central elements are fixed, so there is no need to swap them and think about how to place them. Keep in mind that you will have to repeat the steps below 4 times - one for each edge.

  1. Take the cube so that there was a white layer on top and yellow on the bottom - the one that we have already collected
  2. Look in the top layer for an edge with no white on either side.
  3. Rotate the top layer until the color of this edge and the center piece on the side match, forming an inverted T.
  4. Follow one of the solutions below, choosing an example depending on whether the edge is placed on the left or on the right.

There are several possible options:

1) The edge should move to the right from where it is.

2) The edge should move to the left from where it is now.

Note: If the top layer doesn't have an edge element without white on either side, it means they're in the middle layer but out of place.

Put any other edge from the top layer in its place. In this way, you will get the edge in the top layer without the white square and you can move it, in accordance with the instructions above.

Repeat this step 4 times - one for each edge.

Step 4. Second cross

So, we have collected the first 2 layers of the Rubik's Cube. Now we need to ensure that the 4 outermost elements of the top layer are white, forming a cross. At this stage, we will focus only on the edge elements, not paying attention to the corners.

The top face of a cube can have four white edges, or two, or none. If all four white edges are on the top side, then you can skip this step and go to the next one. If there are two edges, then one of the following options should be used, depending on how they are located relative to each other: side by side or opposite.

1) Adjacent edges

2) Opposite edges are white

3) None of the white squares are right

If there was not a single white square in the top layer, do one of the two options described above and you will get 2 white squares in the top layer. After that, do the necessary sequence of actions, depending on the situation.

Thus, we have laid down the second cross.

Step 5. How to place the second cross

In the previous step, we folded the second cross. In this step, we will make the sides of the cross match in color with the central elements of the corresponding faces. We will only focus on the white edges of the cube, ignoring the corners.

  1. Rotate the top layer of the Rubik's cube until the two edges match in color with the center element of the corresponding faces. If only one edge matches, keep rotating.
  2. Use one of the examples given depending on whether the side edges are in sequential or opposite position with respect to each other.

a) adjacent edges

b) opposite edges

Thus, we have placed the second cross of the Rubik's cube correctly.

Step 6 Place the Corners

We have already put in place all the elements of the Rubik's Cube, except for the corner parts of the last layer.

The goal of the penultimate step is to place the corners correctly, regardless of their orientation. Thus, you need to know exactly when the corner took the correct position.

So, the corner is placed correctly if the nearby center elements match in color with the 3 parts of the corner.

Let's look at a few examples of when the corners are placed incorrectly and when they are in the correct position in order to complete the Rubik's Cube.

It is possible that all 4 corners will be in place from the very beginning (feel free to the next step), or only 1 corner is placed correctly, or none. If only one corner is in place, follow one of the examples below, choosing the one that will allow you to place all the elements in their places.

1) 3 corners out of position (a)

2) 3 corners out of position (b)

3-4) No corner placed correctly

If none of the 4 corners are in "their" place, do one of the above examples - this way you will be able to put one of them in place. Then follow the steps depending on what you got.

Thus, we have completed a 3x3 Rubik's cube, putting the corners in their positions. The last step - by rotating the corners of the last layer, we will solve the puzzle completely.

Step 7. How to assemble

In the previous step, we put all the elements in their places. It remains only to rotate the corners to solve the Rubik's cube and solve it completely. At this stage, there may be two, three or four misdirected corners in the last layer.

If there are 2 incorrectly oriented corners, follow one of the examples below, depending on the situation that has arisen.

Be sure to read this before rotating the faces of the cube.

Very important! This step is not as easy as the others, but also a lot more difficult. Before you get started, there are a few things to know. Option 1 has several sub-options, so the first thing to do is figure out which one is right for you. To solve this step, do the first sequence of actions. After that, take the necessary steps, depending on the version of the red table that you received.

Option 1. Two corners are not correctly oriented. Please note that the "neighboring" corner - needs to be rotated clockwise.

Option 2-3. Three corners are incorrectly oriented.

If 2 corners are not correctly oriented, solve the Rubik's Cube following the first example - this way you will get only 2 incorrectly oriented corners. Finally, do the sequence of actions, depending on the situation that you have.

Option 4. All corners are not correctly oriented.

If none of the 4 corners are correctly oriented, follow the first example given. Then choose the solution that suits your situation.

If you did everything right and followed our instructions so far, then congratulations! You solved the Rubik's Cube by yourself!

And other logic games.

And here, by the way, there is something to show yourself:

  • You can be the fastest. The current record is 5.5 seconds. People who are engaged in high-speed assembly are called speedcubers.
  • Maybe you want to be the most original? The Rubik's Cube is collected with closed eyes, legs, etc. Here, too, there are records and you can beat them.
  • And the most creative and inventive draw with the help of the Rubik's cube and, by the way, create real masterpieces of incredible beauty.

We hope we inspired you and helped you understand how to solve the Rubik's Cube. If you are interested in thinking games and puzzles, you will probably be interested in learning the secrets of playing dominoes. A mixture of options 1 and 2 is suitable for us, in extreme cases, option 2.
If lubricated very liquid, its sides will start to adhere to each other too much. Thick takes away the speed of rotation. If you mix two types of lubricant, it is this consistency that is optimal.

Can't solve rubik's cube...

Many people ask the question: "How to solve a Rubik's cube, if I took it apart, I can't put it back together?". Most often this happens on the last layer. You may not be following the algorithms exactly. But if you follow the diagrams exactly, then it should come together. If not, the problem may be as follows - Chinese manufacturers make dice of different quality - from professional to falling apart in the hands at the first spins. If the cube fell apart, it must be assembled correctly.
On a cube with two layers assembled, pry off the cover of the central cube of the third layer with a flat screwdriver or a knife, remove it, unscrew the screw with a small Phillips screwdriver (do not lose the spring on the screw). Gently pull out the corner and side cubes of the third layer and insert them correctly color by color. At the end, insert and screw the previously unscrewed central cube (do not overtighten). Rotate the third layer. If it's tight, loosen the screw, if it's too easy, tighten it. It is necessary that all faces spin with the same force. After that, close the lid of the central cube.

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. Recently, interest in the cube has been 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.

The World Cube Association (WCA) is a non-profit organization supporting the speed cubing 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 by 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 Y - F is shifted to place L, and when rotated 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.

We should not forget about recording movements using the signs of the 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.

The number of types of Rubik's cubes today is difficult to calculate. However, among all the variety, one can single out classic models, with images on the edges, hybrids of an unusual shape, mirror and virtual. Some models can be easily found on the shelves of the store, others can be ordered in the online store, and still others remain at the prototype stage.

Considering all the options for the Rubik's Cube, it's hard to believe that it all started with one simple model in the mid-80s of the last century. It was then in 1974 that the Hungarian sculptor Erno Rubik invented, and in 1975 patented a puzzle, which is a 3 × 3 × 3 plastic cube with 54 visible colored faces.

The original packaging of the Hungarian Rubik's Cube, 1982

The Rubik's Cube is considered the most popular toy in the world, which has sold a total circulation (original + analogues) of about 350 million copies. However, puzzles are sold all over the world under more than one name. In the original version, Rubik's invention is called the "magic cube", this name is fixed in the Hungarian, German, Portuguese and Chinese languages. In Hebrew, the Rubik's Cube is called the "Hungarian Cube".

The most popular models of the Rubik's cube

It is worth mentioning that not all puzzles presented are Rubik's Cubes. Some models were even invented before 1974, but Rubik's merit is undoubtedly their distribution.

This article provides a step-by-step instruction for beginners, with which you can solve the Rubik's cube using the layer-by-layer method. Compared to other methods, this method is quite simple, because you will not need to remember many sequential actions. Mastering the layering method will help you later on smoothly transition to Jessica Friedrich's quick assembly method, which allows you to solve a cube in less than 20 seconds in competition. In order to conquer this insidious Erno Rubik's puzzle, you will need patience and diligence. Good luck!

Steps

Part 1

Terminology

Familiarize yourself with the three types of elements. There are three main types of elements in the Rubik's Cube, the definition of which depends on their location in the cube.

  • Central the elements are located in the center of the cube on each of its sides, surrounded by the other eight elements. Each such element cannot be moved, and it has only one color.
  • corner elements are located at the corners of the cube. Each element has three different colors.
  • Side the elements are located between the corner elements. Each such element has two different colors.
  • Note. Elements of one type cannot become elements of another. The corner element will always be in the corner of the cube.

Learn to distinguish the six sides of the cube. Each side of the Rubik's cube has its own color, which is determined by its central element. So, for example, the side that has a red element in the center will be the "red side" even if there are no other red elements nearby. However, sometimes it is better to name the sides based on their position relative to the side you are currently looking at. Here are some terms that will be used in this guide:

  • F(Front) - Raise the cube to eye level. Directly in front of you will be the front side.
  • W(Back) is the opposite side that is not visible when you hold the cube in your hands.
  • IN(Upper) - the side facing up.
  • H(Lower) - the side facing down.
  • P(Right) - The side to your right.
  • L(Left) - The side to your left.
  • Master the rotation of the cube clockwise and counterclockwise. When determining the rotation side of a face, it is assumed that the work face is currently in front of you. Thus, a one-letter instruction (for example, L) means you need to rotate the side 90 degrees clockwise (a quarter of a turn). If there is an apostrophe next to the letter (for example, L"), then the side must be rotated 90 degrees counterclockwise. Here are some examples for you:

    • F" indicates that the front side must be rotated counterclockwise.
    • P indicates that the right side should be rotated clockwise. That is, the right side must be rotated away from you. To understand the reason, turn the front side clockwise, and then turn the cube so that this side is right.
    • L says that the left side should be rotated clockwise. That is, the left side must be rotated towards you.
    • IN" indicates that the top side must be rotated counterclockwise when viewed from top to bottom. That is, rotate on itself.
    • W indicates that the back side must be rotated clockwise when looking at the cube from the back side. Look, do not confuse anything, as this rotation is similar to turning the front side counterclockwise.
  • Add a two to repeat the command. The number "2" after the side designation means that you need to rotate the side not 90 degrees, but 180. For example, H2 means that the bottom side needs to be rotated 180 degrees (half a turn).

    • In this case, you can not specify in which direction to turn. The result will be the same.
  • Learn to identify a specific element in a cube. Sometimes the instructions will talk about a particular element in the cube. This will list all the sides that the element is a part of. Here are some examples of the arrangement of elements:

    • NZ= side element that is part of the Back and Bottom sides.
    • WFTU= corner element located between the Top, Front and Right sides.
    • Note. If the instructions say square(one-color sticker), the first letter will indicate which side the square is on. For example:
      • LFN square → find the corner element that is part of the Left, Front and Bottom sides. The square of the required element is on the Left side (according to the first letter).

    Part 2

    Top side assembly
    1. Rotate the cube so that the white center is on side B and let it stay in that position for now. The task of the step is to arrange the side white elements around the center so that they form a cross on the white side.

      • It is assumed that you are holding a standard Rubik's cube in which the white side is opposite the yellow one. If you have an older version of the cube, further instructions are unlikely to help you.
      • Do not remove the white center from the Top side. Do not make the most common mistake in this step.
    2. Move the white side elements up so they form a cross. The Rubik's Cube has many initial configurations, and it is simply impossible to describe a step-by-step instruction for each of them, but we will give you some tips:

      • If the white side square is on the bottom layer of the R or L sides, rotate that side once so that the white square is on the middle layer. Proceed to the next step.
      • If the white side square is in the middle layer of the R or L sides, rotate the side that is next to that white square (L or L). Keep turning the side until the white square is on the Underside. Proceed to the next step.
      • If the white side square is on the Bottom side, start turning that side until the white square is directly opposite the empty (not white) side of the Top side. Rotate the die so that this empty element is on the HF (Upper side next to the Frontal). Perform an F2 rotation (half a turn clockwise) so that the white square is in place of the WF.
      • Repeat the same steps for each white side square until they are all on the Top side.
    3. Extend the cross down to the corner pieces. Take a look at the top side elements of the F, R, Z and L sides. You need to make sure that next to each of these elements there is a central element of the same color. Here, for example, if the side square FV (Front side next to the Top) is orange, then the central square Ф should also be orange. Here's how to achieve this for all four sides:

      • Rotate B until at least two of the center elements of the top layer are the same color as the center elements of the middle layer. If all four elements match, you can skip the rest of the step.
      • Rotate the die so that one of the incorrect side elements is on the F side (and the white cross is still on the B side).
      • Do F2 and make sure one of the white side elements is now on side H. Remember the color of the other square of this white edge (element on FN). Let's say the square is red.
      • Rotate side H until the red square is under the red center.
      • Rotate the red side 180 degrees. The side white element should return to side B.
      • Examine side H for a new white side square. Look again at the color of another square of the same element. Let's assume it's green.
      • Rotate side H until the green square is directly below the green center.
      • Rotate the green side 180 degrees. After all the manipulations, the white cross had to return to side B, and the side elements on the sides F, P, Z and L should be located exactly above the center of the color corresponding to them.
    4. Move the white corner piece to the white side. It's easy to get confused when following this step, so read these instructions carefully. The following actions will result in a white corner element appearing on the white side next to the white center and edges.

      • Find the white corner piece on the H side. The corner piece will have three different colors: white, X, and Y (the white side may not be on the H side by this point).
      • Rotate the H side until the white/X/Y corner element is between the X and Y sides (remember that the X side is the side with the X element in the center).
      • Rotate the cube so that the white/X/Y corner element is in the NFP position. Ignore where the different colors of this element will end up. The center squares F and R should match the colors X and Y. By the way, the top side is still white.
      • From now on, there are three options:
        • If the white square is on the F side (in the FPN position), apply F N F".
        • If the white square is on the P side (in the PFS position), apply P "N" P.
        • If the white square is on the H side (at the NFP position), apply F N2 F "N" F N F ".
    5. Repeat the process for the rest of the corners. Follow the same steps to move the other three white corners to the white side. As a result of this step, you should have a completely white top side. The top layer, consisting of three squares, must match the color of the central element on the F, R, Z and L sides.

      • Sometimes the white corner piece accidentally hits the B (white) side, but ends up in the wrong position, causing the color of the other two squares to not match the center of that side. In this case, rotate the die so that this element is in the WFP position, and then apply F N F. Now the white square will be on the H side, and you can move it to the desired position using the combinations described above.
    6. Part 3

      Assembly of the middle layer
      1. Find the side piece on side H that doesn't have yellow on it. The white side is still in the Top position, and the incomplete yellow side is in the Bottom position. Look at side H and find the side element on it that does not have yellow on it. Mark two squares of this element as follows:

        • Let the square on side H be the color X.
        • And the other square is Y colors.
        • It should be a side element. Do not try to move the corner.
      2. Rotate the whole cube so that the center of the color X is on the Front side. Rotate the cube along its vertical axis (as when rotating a globe). Stop when the side with the center of the X color is on the Front side.

        • In this case, the sides B and H must remain unchanged.
      3. Turn side N. Rotate the H side to either side until the X/Y side piece is in the NC position. The X square should go to the H side, and the Y square to the Z side.

        Spin the cube based on the Y color position. The necessary moves will depend on where the center with the Y color is located:

        • If the Y color matches the center of the R side, apply F N F "N" P "N" P.
        • If the Y color matches the center of the L side, apply F "N" F N L N L ".
      4. Repeat these steps until you have completely collected the top two layers. Find another side piece on side H that doesn't have a yellow square (if there aren't any more, skip to the next step). Follow the same steps as above to move the element to the correct position. As a result, on the sides F, P, Z and L, the upper and middle layers will match in color.

        Make adjustments if all H-side laterals have a yellow square. Be sure to check all four side elements on side H. Each of them has two colored squares, none of which should be yellow, otherwise all your actions in this section will go down the drain. If none of the side elements fit this description (and the top two layers are not finished yet), make the following changes:

        • Find the side element containing the yellow square.
        • Rotate the cube so that this element is in the FP position. The white side should remain on side B (move the whole cube, not the sides).
        • Apply F N F "N" P "N" P.
        • Now on side H there should be no side elements with a yellow square. Return to the beginning of the section and repeat all the steps for this side element.
      5. Part 4

        Assembly of the yellow side

        Rotate the cube so that the yellow side is up. The cube will remain in this position until it is completed.

      6. Collect the cross on the yellow side. Pay attention to the number of yellow side elements on side B (do not confuse corner elements with side elements). You have four options:

        • If side B has two opposing yellow side pieces, rotate side B until both pieces are in the TL and VP positions. Apply Z L V L "V" Z".
        • If there are two adjacent yellow elements on the B side, move them to the positions VB and VP (forming an arrow when one is facing back and the other is facing left). Apply Z V L V "L" Z".
        • If there are no yellow elements on side B, apply one of the algorithms described above to move the two yellow side elements to the top. Then again use the algorithm that matches their location.
        • If there are four elements on the side, you have successfully collected a yellow cross. Proceed to the next step.
      7. Move the yellow corner piece to side B. Turn the cube until the blue side is in front and the yellow side is on top. Move the yellow corners like this:

        • Rotate side B until the yellow square of the corner piece on the VFP is on side B.
        • There are two possible actions for the corner:
          • If the yellow corner square is on the F side, apply F N F "N" F N F "N".
          • If the yellow corner square is on the R side, apply N F N "F" N F N "F".
        • Note: at this stage, the cube will look jumbled. Don't worry, everything will fall into place later.
      8. Repeat the same steps for the remaining yellow corners. Keeping the blue side on F, rotate B to move the next corner to the WFP position. Repeat these steps until the entire yellow side has been collected.
