How to collect a Rubik's cube without breaking your head. Schemes with pictures for beginners and children. How to collect a rubik's cube and save the nervous system To assemble a 3x3 rubik's cube is the easiest
The famous puzzle, which consists of several colored sectors combined into one cube, appeared in 1974. The Hungarian sculptor and teacher decided to create a study guide to explain group theory to students. To date, this toy is considered the best-selling in the world.
But, success to this puzzle came only when German entrepreneur Tibor Lakzy drew attention to it. He, together with the game inventor Tom Kremer, established not only the release of the dice, but also organized the promotion of this puzzle to the masses. It was thanks to them that competitions on the high-speed assembly of Rubik's cubes appeared.
By the way, people who are engaged in this assembly of this puzzle are called speedcubers ("speed" - speed). It is not difficult to guess that the speedy assembly of the “magic” cube is called speedcubing.
The structure of the Rubik's Cube and the names of the rotations
In order to learn how to assemble this puzzle, you need to understand its structure and find out the correct name of certain actions with it. The latter is important if you are going to find instructions for assembling the cube on the Internet. Yes, and in our article we will call the whole action with this puzzle, according to well-established expressions.
A standard Rubik's Cube has three sides. Each of which consists of three parts. Today, there are also 5x5x5 cubes. The classic cube has 12 edges and 8 corners. It is painted in 6 colors. Inside this puzzle is a cross around which the sides move.
At the end of the cross is a square with one of six colors. Around him, you need to collect the remaining squares of the same color. Moreover, the puzzle is considered assembled if on all six sides of the cube its color is assembled.
IMPORTANT: In the original puzzle, yellow is always opposite to white, orange is red and green is blue. And if you disassemble the puzzle, and then fold it wrong, then this can lead to the fact that it can never be assembled.
In addition to the centers of the cube, the corners are the constant components of this puzzle. Each of the eight corners consists of three colors. And no matter how you change the position of the colors in this puzzle, the composition of the colors of the corners in it will not change.
IMPORTANT: The Rubik's Cube is assembled by placing the corner and middle sectors in accordance with the colors of the central sectors.
Now that we understand, the construction of this puzzle is time to move on to the names of the sides and rotations and their designation in the specialized literature.
In the process of assembling the Rubik's Cube, it may be necessary not only to move the sides, but also to change the position of this object in space. Specialists call these movements interceptions. Schematically, it is displayed like this:
IMPORTANT: If only the letter is indicated in the cube assembly algorithm that you found, then we change the position of the side clockwise. If after the letter the apostrophe sign “’ ”is indicated, then we rotate the side counterclockwise. If after the letter the number "2" is indicated, then this means that the side must be rotated twice. For example, D2 ′ - rotate the lower side counterclockwise two times.
A simple and easy way to build: Instructions for children and beginners
The most detailed assembly instruction for beginners is as follows:
- At the first stage of assembling this popular puzzle, we start with the right cross. That is, from the fact that on each side of the cube the color of the edges and centers will be the same.
- To do this, find the white center and white edges and collect the crosses according to the diagram below:
- After the above steps, we should get a cross. Of course, the cross will not be right the first time and you need to slightly transform the resulting version. With proper execution, it will be quite simple to swap the ribs between each other.
- This algorithm is called “bang-bang” and is shown in the diagram below:
- We proceed to the next step in assembling the puzzle. Find the white corner on the bottom layer and set a red corner over it. You can do this in different ways, depending on the position of the red and white corners. We use the “bang-bang” method described above.
- As a result, we should get the following:
- We begin to collect the second layer. To do this, find four edges without yellow color and place them between the centers of the second layer. Then twist the cube until the color of the center matches the color of the face element.
- As with the previous layer, to achieve this you may need one of several options:
- After we have successfully completed the previous step, we proceed to the assembly of the yellow cross. Sometimes, he "gathers" himself. But, this happens very rarely. Most often, the cube at this stage has three options for arranging colors:
So the yellow cross is assembled. Further action in solving this puzzle is reduced to seven options. Each of them is shown below:
In the next step, we need to collect the corners of the top layer. Take one of the corners and put it into place using the movements U, U ’and U2. This should be considered. So that the colors of the corner are identical to the colors on the lower layers. When using this step, hold the cube in white towards you.
Next build step - The final stage of cube assembly is the assembly of the ribs of the upper layer. If you did all of the above correctly, then four situations can arise. They are solved very simply:
The fastest way. Jessica Friedrich Method
This puzzle assembly method was developed by Jessica Friedrich in 1981. It is conceptually no different from most known methods. But, it focuses on build speed. Due to this, the number of assembly steps was reduced from seven to four. To master this method, you need to master “only” 119 algorithms.
IMPORTANT: This technique is not suitable for beginners. You need to study it when your cube assembly speed becomes less than 2 minutes.
1. At the first stage, you need to collect a cross with side faces. In specialized literature, this stage is called "Cross" (from the English. Cross - cross).
2. In the second stage, you need to collect two puzzle layers at once. They call him "F2L" (from the English. First 2 Layers - the first two layers). To achieve the result, the following algorithms may be required:
3. Now you need to collect the top layer completely. Paying attention to the sides is not worth it. The name of the OLL stage (from the English. Orientation of the Last Layer - orientation of the last layer). To build, you need to learn 57 algorithms:
4. The final stage of assembly of the cube. PLL (from the English Permutation of the Last Layer - arranging the elements of the last layer in places). Its assembly can be carried out using the following algorithms:
3x3 rubik's cube assembly diagram in 15 moves
Since 1982, when the competition for high-speed assembly of the Rubik's Cube appeared, many fans of this puzzle began to develop algorithms that will help to correctly arrange the sectors of the cube with a minimum of moves. Today, the minimum number of moves in this puzzle is called "God's Algorithm" and is 20 moves.
Therefore, in 15 moves it is impossible to collect the Rubik's cube. Moreover, a few years ago, an 18-way algorithm for assembling this puzzle was developed. But, it can not be used from all positions of the cube, and therefore it was rejected as the fastest.
In 2010, scientists from Google created a program with which they calculated the fastest Rubik's cube assembly algorithm. He confirmed that the minimum number of steps is 20. Later, the Lego Mindstorm EV3 robot was created from the details of the popular designer, which is able to assemble the Rubik's cube from any position in 3.253 seconds. He uses a 20 step in his "work" "Algorithm of God". And if someone tells you that there is a 15-step cube assembly scheme, do not believe it. Even the power of Google "is not enough" to find it.

TOP 10 world records for assembling the Rubik's Cube for speed:
Date: 2012-11-20 Editor: Zagumenny Vladislav
Stage 1. Get to know the 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 angles- these are parts with three colors. In total, the cube has 8 angular parts 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 indicated by a Latin letter
R - right side - the right side of the cube
L - left side - left side of the cube
U - top face - top side of the cube
D - bottom face - bottom side of the cube
F - front face - front side of the cube
B - back face - the back side of the cube.
Comment:the letter “i” after the letter of the face means reverse movement or counterclockwise movement when looking directly at the face.
Very important
When performing the movements below, keep the cube fully turned with one face toward you, as shown in the figure. The dark gray color in the pictures means that the real color of these parts does not matter. Every movement is one fourth full turn 360 degrees.
Stage 2. We collect a white cross.
Task:Holding your cube so that the white center is located on the upper edge (U), you must collect the white cross as shown in the figure below. Most of this stage is achieved through trial and error, but still there are a few tips.
Tips:
Be sure to remember that you need to collect parts of the white cross in the following order - blue, orange, green, red.
Note that the edges in the figure above combine with the upper white center and the side red or blue center. Thus, you can simply determine that the edges are in the right places.
Keeping the position of the white center on the upper face, move the white-blue edges to the lower face (D). Next, rotate the bottom face until the white-blue rib is directly below the blue center. Now take the cube so that the blue center and the white-blue edges are on the right side (R).
Turn the right edge (R), 
until the white-blue edge is on the upper (U) face above the blue center.
If your cube looks like in the figure below, take the cube so that the orange center is on the right side and assemble the side with the orange center in the same way.
If your cube looks like the image below, then follow the sequence below, making sure that the blue center is on the right (R) side.
The remaining parts of the white cross are assembled in the same way.
Congratulations!
If the white cross on your cube is the same as in the figure, then you can go to stage 3!
Stage 3. We collect white corners.
Task:take the cube so that the white cross is on the top face (U). Now you need to collect the white corners, and get a cube as in the picture below.
Tips:
Corners will have one white face and 2 faces of other colors.
If the corner is already on the lower edge, then rotate the lower edge until the angle is directly below the place where it should be. After that, your cube may look like one of the 3 three images below.
Repeat the whole process for all four corners.
If the corner is located on the upper face, then move it to the lower face, following the sequence:
Now rotate the bottom face until the corner is directly below its place on the top face.
Congratulations!
If your white layer looks the same as in the picture below, then you have collected one third of the cube and you can go to stage 4.
Stage 4. We collect the middle layer.
Task: Take the cube so that the fully assembled white layer is on the bottom. Now you need to collect the middle layer, arranging the side ribs in their places.
Tips:
Pay attention to the vertical blue strip (it can also be red, orange, green) - this is critically important.
Gather such a vertical strip 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 upper part of the rib on the upper face determines the direction of movement of the rib, that is, in which direction this part should shift.
1) If you move the edge in the same direction as in the figure, then follow the sequence of pictures below.
2) If you move the edge in the same direction as in the figure, then follow the sequence of pictures below.
Repeat these steps until all the side ribs are in place.
Comment: if one of the edges is already in place, but not correctly oriented, perform one of the sequences presented above, and it will appear in the upper layer. After that, follow the appropriate sequence of actions to place the edge back in its place in the middle layer.
Congratulations!
If the two lower layers on your cube look the same as in the picture below, you can proceed to stage 5. You have gone two third ways!
Stage 5. We collect the top layer. We get a yellow cross.
Task: Compare the state of the yellow face of your cube with the patterns below. Next, follow the appropriate sequence.
Hint:the yellow parts on the top face so far should not coincide in color with the side faces.
Step one: Gather the yellow cross.
Switch to step two and start collecting the corners of the yellow face.
Follow these steps:
Option 3
Option 4
Step Two: Make all the corners of the upper face yellow.
Take a look at the top face and compare the state of the cube with the options presented below.
If there is not a single yellow corner on the upper yellow face, then you must take the cube so that the yellow face of one of the corners is on the left side of the cube. See picture.
If there is one corner on the yellow face, follow the sequence below.
Option 3If there is not a single yellow corner on the upper yellow face, and also there is not a single angle that could be used in option 1(that is, at all angles the faces are located on the right). Then take the cube as shown in the figure 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 cube 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 into place.
In 1975, the sculptor Erne Rubik patented his invention under the name “Magic Cube”. For over 40 years, all rights to the puzzle belong to the company of Tom Inner's close friend, the inventor, called Seven Towns Ltd. The English company 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.
Varieties of puzzles
The classic Rubik's Cube measures 3 by 3 squares. Over time, came up with a huge number of shapes and sizes for toys. No one will surprise anyone with a puzzle in the form of a pyramid or a 17x17 cube size. However, humanity never rests on its laurels.
Obviously, there is no assembly scheme for the beginners of this cube. The process of assembling and solving the puzzle may take years. Recently, 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 shot a video assembly of the puzzle 17 on 17. 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 sold 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 organize real competitions in cube assembly speed. Special speed puzzles are on sale. The rotation mechanism of such Rubik's cubes is very high-quality, and the turns of faces and rows can be made with the movement of one finger.
The World Cube Association (WCA) is a non-profit organization supporting the speedcubing movement. The WCA regularly hosts competitions around the world. In almost all countries there are 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 standards. The most popular discipline in such competitions is the high-speed assembly of the Rubik's Cube 3x3. The norm for participation is 3 minutes, but even if a person cannot solve the problem in the allotted time, he will still be allowed to attend the event. You can sign up for any discipline, but you need to come with your puzzle.
The 3x3 Rubik's Cube assembly record belongs to the Sub1 robot, created by engineer Albert Beer. The machine is able to solve the puzzle in a split second, while a person will need 4.7 seconds to achieve it (achievement of Mats Valka 2016). As you can see, the participants in the speedcubing movement have someone to look up to.
What are the algorithms for assembling a Rubik's Cube 3x3?
There are many ways to solve a well-known puzzle. Variants of 3x3 Rubik's cube assembly schemes have been developed for both beginners and advanced people with complicated schemes: 4x4, 6x6 and even 17x17.
The 3x3 puzzle option is considered a favorite classic for most fans. Therefore, there are much more instructions on how to assemble 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 previously prepared position. If the patterns on the faces of the cube are not located correctly, then it will not work for the beginners to solve it using the 3x3 rubik's cube assembly algorithm. There is a set of such positions for different solutions.
The figure shows or simply a “cross” - the starting point of the easiest way to assemble 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 you begin to disassemble the formulas of the Rubik's Cube 3x3, 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 carried out clockwise, if there is a sign, then it should be rotated 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 upper row;
- down -D or H - rotation of the bottom row.
Pointers can also be used to change the position of the cube in space - the interception movement. Everything is simple here, too, from the school course of geometry, the coordinate axes X, Y and Z are known to everyone. The X movement means that the cube must be rotated by the F face to the place of the U face, when Y - F is shifted, it should be replaced by L, and when Z is rotated - F moves to R.
The following group of notations is rarely used; it is used in drawing up patterns of patterns:
- M - the rotation of the middle row, between the right (R / P) and left (L / L);
- S - rotation of the middle row, between the front (F / F) and the rear (B / T);
- E - rotation of the middle row, between the upper (U / B) and lower (D / H).
Why collect patterns on the faces of the cube?
At meetings on speedcubing they compete not only in solving the 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 assemble 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. There are more than 46 of them for the classic puzzle alone. Speedcubing masters consider it shameful to disassemble the toy. Also, drawing patterns on a 3x3 Rubik's Cube is a great way to train and improve skills.
The figure depicts options for various puzzle patterns. The following are some more formulas for assembling the most interesting drawings from the cross position:
- chess - M 2 E 2 S 2;
- zigzag - (PLFT) 3;
- four z - (PLFT) 3 V 2 H 2;
- plummer's cross - TF 2 N "P 2 FNT" FN "VF" N "L 2 FN 2 V";
- a cube in a cube in a cube - In "L 2 F 2 N" L "HB 2 PV" P "In 2 P 2 PF" L "VP".
3x3 Rubik's Cube Build Algorithm for Beginners
Although there are many ways to solve the puzzle, simple and understandable schemes for beginners are not so easy to find. With each passing step of the assembly, the formulas of a 3x3 Rubik's Cube become more complicated. It is necessary not only to change the pattern correctly, but also to preserve what has been done before. Below will be one of the options for how easy it is to assemble a 3x3 Rubik's Cube.
Conventionally, the whole process can be divided into the following stages:
- The assembly of the cross in the upper face of the cube.
- The correct preparation of the entire upper face.
- Work on the middle layers.
- Proper assembly of the ribs of the last row.
- Assembling the cross of the lower bound.
- Correct orientation of the corners of the last face of the cube.
Puzzle Solution - Preparatory Work
The first stage is the easiest. Beginners can try their hand and practice drawing cube patterns according to the instructions, but this process will take a lot of 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 is designed from the “cross” position. Make it easy, you need to select the central color, find 4 rib elements of the same shade and raise them to the selected face. The colored arrow in the picture indicates the part to be found. Variants of the location of the desired element may be different, depending on this, 2 sequences of actions A and B are described. The difficulty is to continue the cross on the sides of the cube. A closer look at the final form of the stage can be in the image above.
Puzzle solution - work on the middle row
At this stage, beginners need to find and assemble the corner elements of the upper facet of the Rubik's 3x3 cube assembly diagram. In the end result, the face with the cross and the top row of the puzzle must be completely solved.
The image shows three cases of a possible pattern of faces. 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, skills and mastery of puzzle assembly 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 composed. Applying them, it is worth remembering the preservation of previously achieved results. Masters constantly keep 3-4 last rotations in their memory in order to return the cube to its original state in case of failure.
To solve the puzzle, you need to rotate it along the coordinate axis in the search for 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 rib faces from the elements of the lower rows, after such rotations all the necessary cubes will go down from the middle to the lower row.
Puzzle Solution - Making the Second Cross
At the fourth stage, the toy is turned upside down. Solving the last facet is the most difficult part of the Rubik's 3x3 cube assembly algorithm for beginners. The rotation formulas are long and complex, their implementation will require special care. The purpose of the action is to position the rib elements in their places for further drawing up the cross. The orientation of the rib parts may be incorrect. The formula for the movements of the cube is only one, and it should be applied until the goal of the stage is achieved.
The rotation of the fifth stage is aimed at the rotation of the elements on the right side. Its peculiarity lies in the fact that the same rotation formula is used for all three patterns in the figure, the only difference is in the orientation of the cube itself.
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".
С Н is the rotation of the middle row clockwise, and the exponent above the bracket is the number of repetitions of the actions in parentheses.
Puzzle Solution - 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, which is already in the right place, is located in the far left corner at the top of the cube. The options proposed for solving the formula mirror each other. Repeat the rotation is necessary until the desired result.
The seventh stage is the most solemn and the most difficult. When the cube rotates, violations in the already assembled rows are inevitable. It will be necessary to completely focus on the movements, otherwise the result of the assembly may be irrevocably ruined. As in the fifth stage, the sequence of movements is only one, but repeated 4 times. First, rotations are made to orient the element, then reverse to restore broken rows.
Do not forget about the recording of movements using signs of the English alphabet. The formulas for the movements of the faces and rows of the cube of 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 - rotation of the upper face by 90 degrees, B "- rotation of the same face counterclockwise, and B 2 - double rotation.
The complexity of the stage is in the correct assessment of the arrangement of elements and the choice of the necessary rotation option. It can be difficult for beginners to immediately correctly determine the pattern and compare 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 world champions in assembling the Rubik's Cube. In 2015, Colin Burns, who at that time was only 15 years old, assembled the toy in 5.2 seconds.
A simple but exciting toy continues to interest the younger generation for the past 5 decades. Children's hobby often develops into a profession. There are mathematical methods for evaluating solutions to problems of the Rubik's Cube. This section of mathematics is used in the design and writing of decision algorithms for automated computers. Robots that are really looking for ways to build a cube, and do not perform a pre-driven motion algorithm, solve the puzzle in 3 seconds, for example, CubeStormer 3.
How to forget about incomprehensible schemes and collect a Rubik's cube according to the scheme for beginners?
If you still cannot solve the puzzle without being upset: 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 set yourself the task, then after reading the article it will become easy.
But if you do not know how this very mysterious cube is built, what it consists of and how it functions, the task becomes complicated at times.
How to collect a Rubik's cube according to the scheme for beginners in Russian, you will learn below, but remember that you should not underestimate the complexity of the presented.
An ordinary 3x3 rubik is a small mechanical 3D cube whose edges are painted in different colors.
Putting a Rubik's Cube Let's analyze the components of a cube in particles.
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 “right” position.
There are a bit more angular elements - 8, and they have three different colors.
Do 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 to the problem completely depends on the knowledge of 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 certain type, it can not be changed after rotation.
Puzzle Basics
If you want to know how to assemble a Rubik's cube, we have a special scheme for beginners in Russian.
Set yourself - let the elements fall into place. Focus on the center, only the cubes there do not change their position.
For example, an edge between red and green is red-green.
Take a rule for yourself: a green edge must be of the same color.
Diagram 1. Correctly spaced particles are depicted in blue, those that can be changed in green - yellow, on which action is performed You should not lose sight of the angle; it is always three-colored and placed between the central elements of the colors that correspond to it.
How to collect a Rubik's Cube - a step-by-step scheme for beginners in pictures
It is necessary to collect the edges of one side. To get started, select the color to be first. Let it be yellow. So, let's begin!
Turn the cube in yellow upward, so white remains below, this markup is represented in almost all existing models.
Tip: if you are interested in how to assemble a Rubik's cube, use the 3 by 3 scheme for beginners in Russian. At the top you need to fold the cross, for this, put the edges of the color you selected in position. They will correspond to the central element.
Using our advice, remember what to do in order.
The second color of the rib should correspond to the central particle that is closest. Practice and you will succeed.
The main thing is 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 you will need to do this 4 times - for each side.
- The cube should be in your hands, turn it over, there should be a yellow center element on top, or one, the color that you selected, below - white
- See if there is yellow below, and pay attention to both colors of the rib
- In the event that you have found a yellow square, twist the cube until the edge takes its place on top
- Continue to follow the instructions on how to collect 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 the yellow color from above, but it is not in its place or is incorrectly oriented relative to the center, change its position by simply placing another particle in its place.
The edge will stand in the position described earlier, with the help of the circuit, it will fall into place.
So you need to do 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. Need to put the corners in place.
If you put them the way you want, nothing will work out - each has its own place. It is determined by the colors of which it consists.
Do not forget that any performed actions will need to be repeated 4 times for all angles.
- Put the cube in its original position, as in the previous time
- Try to find the corner in which the yellow square will be in the lower layer, stop your attention on several colors on it
- Turn the bottom, the corner should be under its place
- You can choose one of several solutions: yellow on the left, right and bottom
We move on to the next facet, while not forgetting about the central elements. They are fixed in place, so you need to change their places and think about how best to place them.
We repeat all actions, as before, 4 times.
- This time you need to take the cube with the white layer up, below it will turn yellow, already assembled.
- Locate in the top layer edges without white on both sides.
- Scroll upward so that the colors of the edge and center are completely the same, it will be very similar to the inverted T.
- Choose one of the presented examples, your decision should depend on whether the edge is located - on the left or on the right. Here are some options to choose from: the edge is moved to the right or the edge is moved to the left.
If you could not find elements in the layer without white on either side, this means that they are in the middle.
To correct this situation, rotate the other edge from the top layer to its place. You can continue your work by following the instructions.
Putting the second cross together
Now that you have already collected 2 layers of the cube, let's try to make the 4 extreme elements of the top white.
It is necessary to focus exclusively on edge particles, bypassing corners.
Still do not know how to assemble a Rubik's cube according to the scheme for beginners in Russian? Themed video will come to your aid.
So, if the first 4 white edges are already at the top, go to the next step.
But if 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 nearby or vice versa: adjacent edges, opposite edges are white, not a single snow-white square is right.
If you try to fold the cross in one of the above ways, then if there is not a single bright square at the top, the result: 2 finished squares.
Depending on the combination received, select your option, this may be the first or second plus the 4th step.
The second cross is ready. To the side parts coincide in color with the center, repeat the steps of the fifth section.
Turn the top of the cube until the two edges coincide in color with the center. The second cross is in place.
Placement of corners
The particles have already found their place, and you already almost completely know how to assemble the Rubik's cube according to the scheme for beginners in Russian by video, it remains only to complete the corners.
This must be done, not paying attention to their orientation, you should know when it becomes in its position.
Tip: the angle is correct when the close central parts coincide in color with 3 parts.
We will show you in what situations the angles are wrong and right for the assembly.
Of course, it can also happen that 4 corners will fall into place initially.
If 1 is in place, follow one example:
- Turn the edge forward, upward to the right, the other edge - forward, again to the side, but the left, down, to the right, the other edge - down, and the reverse - to the left
- Left edge - up, right - left, forward, right, left - down, right - left, down, right
So, we have assembled a 3x3 cube together, if you are interested in how to assemble a Rubik's cube, there is a special scheme for beginners in Russian and for a 2x3 cube.
I want to believe that we were able to help you, and you collected the Rubik's Cube.
This is a rather fascinating activity that will help your mental abilities and motor skills of the fingers.
