What is the mystery of the Rubik s Cube, and what is the principle of the Rubik s Cube

In fact, according to the color of the center block on each side, the edges and corners are "matched" and "aligned".

The Rubik's Cube has 6 colors and 6 faces, and the international fixed colors: white is the base formula D, yellow is the top formula U, blue is in the front formula F, green is in the back formula B, orange is in the left formula L, and red is in the right formula R. The cube is divided into 6 central blocks (the middle block on each side), 8 corner blocks and 12 edge blocks.

The central block is a fixed structure, and the Rubik's Cube is restored by rotating the corner blocks and edges.

The mantra of the Rubik's Cube

1. Up, right, down, right, backward, left, - swap the positions of the small squares on the two adjacent vertices above.

2. Talk about the upper left and the lower down - exchange the position of the small squares on the two vertices of the upper corner.

3. Up, left, down, left, up, left, left, left, left, the small squares on the three vertices above are rotated 120 degrees at an angle.

4. Left, left, left, right, right, right, on the land, exchange the small squares in the middle of the three edges in turn, and ensure that all the other small squares do not move.

All mantras ensure that the position and angle of the small square below the foolish touch remain the same. You can start with one side of the Rubik's Cube and use this as the bottom. And then:

1. Adjust the position of the four small squares on the vertices above with the formula.

2. Adjust the angle of the four small squares on the vertices above with formula 3.

3. Use formula 4 to adjust the other small squares located on the edge.

The secret formula for the Rubik's Cube is (rur'u'）（r'f）（r2u'r'u'）（rur'f'）、uz（u'rd'）（r2ur'u'r2u）z'（ru'）u’、（rur'f'）（rur'u'）（r'fr2u'r'u'）。There is also (r2u.)'r'u')(ruru)(ru'r)、(ruru2)(r'l'uru'l)(u2r2。”

The special processing formula of the fifth-order Rubik's cube is uw2 ( mr2 u2 )2 mr2 uw2, rw u2 cr (rw u2)2 rw' u2、lw u2 rw' u2 rw u2 rw' u2 rw'。

There are many kinds of reduction methods of the third-order Rubik's cube, and the complex reduction methods include zb methodzbigniew, vh methodlars, zz method, as well as 8355 reduction method, bridge reduction method, cfop, cfce, etc., these more complex reduction methods have complex formulas and many rotation steps.

The secret of playing the Rubik's Cube is mainly by memorizing the rules of the Rubik's Cube formula and practicing more, after the Rubik's Cube formula is memorized, you can exercise the most suitable Rubik's Cube by yourself after practicing proficiently, the specific methods are as follows:

1. First adjust one side of the Rubik's Cube as the top and adjust the second row.

2. Take the top of the Rubik's cube as the reference surface, adjust the corresponding center point, and then adjust the point directly below to the right point and left point of the second row.

3. Then straighten the bottom cross.

4. Vertical bar, with the top as the reference surface, adjust the three points of the same color in the middle of the four sides of the side.

5. The four corners are based on the positive and bottom surfaces, one point is the fixed point, and the other three points are changed to correct the four corners below.

6. Fix the point at the upper right corner of the front and bottom surface, season the other three points counterclockwise, and then use the upper left corner of the front and bottom surface as the fixed point.

Precautions: 1. If you can't restore the Rubik's Cube all the time, you can consider memorizing the formula, because memorizing the formula is the most basic, and the basis of any playing the Rubik's Cube is to memorize the formula.

2. Be sure to wash your hands before playing the Rubik's Cube, and no matter how anxious you are to play the Rubik's Cube, you can't touch it with a pair of greasy dirty hands.

3. If the child is interested in playing the Rubik's Cube, parents can encourage them to play, because if the child has not gone to school when he is young, he can have a lot of time to play the Rubik's Cube.
