The Rubik's Cube is a popular puzzle of all time. Despite the apparent simplicity, it is not easy to collect faces of the same color. We offer you a number of schemes so that you can choose the best for yourself. So, how to learn how to solve a Rubik's Cube - a detailed guide for children and adults.
First - assemble the right side
We recommend starting the assembly on the right side of the cube. There are a lot of options for action here, we won’t describe them all - we’ll focus on the main ones. Try not to cram formulas, but to understand their essence. An approximate scheme of actions is in the pictures, for understanding the actions are signed in stages (1, 2, 3 ..., a-b-c).
Volumetric cross on the right
On one side of the cube, assemble a cross, the colors of which will correspond to the shade of the squares in the center on the other sides. Find a suitable cube with ribs, rotate the front part so that the structure moves up. Repeat these steps for a given number of times.
Sometimes rotations break already assembled structures. In this case, move the cube you found to another plane. If it's not at the top, go back to the first step. When moving to another plane, “breakdowns” are also likely. Eliminate them in the same way as described above.
When the found cube goes up, use one of the schemes. These are examples of combinations, other options are also used.
Sides and belts
The next step is how to solve the Rubik's Cube. Here is one of the many possible schemes of action, so that you have something to focus on. The task is to arrange the corner cubes and complete the step. Then remove the wrong corner. If the cube hides below, move it to the lower belt, fix it in a new place using the above formulas.
Another belt
The next step in the instructions for the Rubik's Cube is the assembly of the second belt. Two formulas will do - use any of your choice. Find a suitable option in the third belt zone, you need both shades (if there is another belt) to be combined. Move the found combination to the second belt diagonally.
If there is no suitable cube, use the same schemes, but with reservations. You will need to move any die from the third belt to the second line. If everything is done correctly, the desired option will appear.
Cross on the other side
When the previous steps are completed, start collecting the cross from the opposite side of the cube. It is created without the third line and taking into account its colors. That is, at this stage, only the cross is collected and coordinated with the shades of the third belt in the future.
To switch between combinations, use the combination F P V P' V' F'. It is repeated up to 3 times, taking into account the moment which combination was used earlier. If the cross is already assembled, the step is skipped. When there is only one square, the central one, the formula is repeated three times, with an angle twice, if we are talking about a line, then one.
See the pictures for how to solve a Rubik's Cube. Before starting the formula, arrange the squares exactly as shown in the figures.
Make an agreed cross
The next step in how to solve a Rubik's Cube is to make a cross. It should be consistent with the shades of the belt. Rotate the upper belt until the shades match the squares located in the upper belt in the center. There are only two possible combinations - coincidences in a line or an angle.
Move cubes that are not correctly placed in the cross and are located opposite each other. When you complete the formula from the picture, rotate the top belt until the pair of colors completely matches the middle squares on the top belt. If the pair of ends of the cross does not fall into the required places, the combination will change to match the colors with an angle.
Swap the cubes of the cross that were placed incorrectly, located diagonally among themselves (we are talking about a pair of adjacent cubes). After the formula is implemented, the cross is ready, and the tones will begin to match the colors on the upper belt. If you don't get the results you want the first time, repeat the steps.
Arrange the corner cubes
Corner cubes are placed using a couple of the following formulas. If you follow the instructions, it will turn out to put the corner cubes each in its place, without errors in turns. A black dot is a cube that is in its place, but turned the wrong way.
Unfolding corner cubes
The turn of the corner sides is performed according to the P'N'PN scheme, it will need to be repeated the required number of times. Before beginning, read the section carefully and make sure there are no questions. One wrong action and the result will not be the same.
After the start of assembly-disassembly, the cube will be disassembled. It will be collected only as the corner cubes turn correctly. The thing is that all the corner sides are unfolded in one operation, maximum endurance and patience are required. From the first time everything turns out even according to the instructions rarely. Be patient, if something does not work out, go back and repeat the steps.
important points
Recommendations to consider when assembling:
- The standard 9-way formula is performed 1-2 times until the corner cube is in the desired position.
- When the corner cube returns to its correct position, the rubik will collapse. You don't need to do anything yet - everything will be restored when you finish working with the corners.
- Do not spin the die until the end of the last step.
- When you set the first corner cube (see pictures above) correctly, rotate the top layer and the next corner cube will move to the upper right corner. If the rotation is already correct, repeat the rotation of the top layer.
Repeat the 8-way formula (up to 2 times, depending on how it works out) and follow the recommendations above. Repeat the steps until the corners are set correctly and the rubik is fully assembled. If it doesn't work, take a few steps back to analyze where the mistake was made and fix it.
Now you know how to solve the Rubik's Cube quickly, you can spend family evenings with children or yourself with maximum interest.
