Three-step Rubik's cube formula diagram is restored in seven steps. I believe everyone is no stranger to the Rubik's Cube. Many people like to play Rubik's Cube. The third-order Rubik's Cube is the simplest imitation. Knowing some skills can help us quickly restore the third-order Rubik's cube. Next, I'll take you to know about the seven-step reduction of the formula diagram of the third-order Rubik's cube.

Three-step Rubik's Cube Formula Illustration Seven-step Reduction 1

Rubik's cube is called Rubik's cube in Taiwan Province province and twisted dice in Hongkong. To solve the Rubik's cube, we must first understand the structure of magic. As can be seen from the diagram of the third-order Rubik's Cube formula, the Rubik's Cube has six colors and six faces, and each face is divided into a central block (six in the middle), a corner block (eight in four corners) and a side block (four in the middle 12).

The central block has only 1 face, and all of them are fixed structures, so the central block is red, so all other reds should be concentrated on this face, and the fixed one opposite to red must be orange. Then we use different letters to replace each face, just like the schematic diagram of the third-order Rubik's Cube formula, and then use letters to indicate the 1 layer or 1 face to be rotated, and the direction: for example, r (representing the right side rotates 90 degrees clockwise), R' (representing the right side rotates 90 degrees counterclockwise), and R2 (representing the right side rotates 90 degrees clockwise twice).

Finally, the names of each party are relative. For example, F is the front, that is, the side facing you when holding the Rubik's Cube. If the imitation is rotated to the other side, the new side will become the front.

Seven-step reduction method of third-order Rubik's cube

1. Look at the schematic diagram of the third-order Rubik's Cube formula first. According to the first step, put the white square in the middle towards the top, and then make a white cross on the top, that is, the squares of other colors will go to the corresponding positions.

2. Then put the white corner back in place.

3. Then put the middle side block back in its original position. Turn the white surface down and find the red and green edge blocks. If the red and green edge blocks are on the top floor, turn the top floor clockwise until the edge blocks are the same as 1 in the figure. Then, according to the formula, the Rubik's cube is rotated to make the side block return to its original position. If the red and green edge blocks are in the middle layer, but the position or color is wrong, first make the red and green edge blocks in the right front position, and then rotate them 1 time according to one of the following orders.

4. Then adjust the top side block (which should be yellow) upwards to make a yellow cross. If a yellow cross does not appear on the top floor after rotating 1 times according to the formula, you can rotate it repeatedly according to the formula until a yellow cross appears.

5. Then adjust the yellow corner around the cross, which is a bit difficult. See formula.

6. Usually, at this time, the yellow blocks will be misaligned with the color of the side, and the yellow blocks at the four corners will be positioned according to the formula.

7. Finally, adjust the color block on the side to the corresponding position. You're finished.

The face of the Rubik's Cube is represented by the following letters: the front f; Behind b; L left; R right; U top floor; Bottom floor. Letters only represent orientation, regardless of color.

During the operation of the Rubik's Cube, writing a single letter indicates that the face rotates 90 degrees clockwise, adding a comma after the letter indicates that the face rotates 90 degrees counterclockwise, adding a number 2 after the letter indicates that the face rotates 180 degrees, and adding a comma and a number 2 after the letter indicates that the face rotates 180 degrees counterclockwise.

1, return to the second layer prism, and use the formula URURUFUF.

2, top cross, using the formula FRURUF.

3. Return the middle block at the top edge and use the formula RURURUUR.

4. Make the top cross into a small fish state and use the formula RURURU2R.

5. Restore the state of the small fish to the vertex position and use the formula RULURULU.

6. Restore the vertex angle to the top edge and use the formula F2URLF2RLUF2.

7. Return the top edge to the top corner and use the formula R2B2RFRB2RFR.

When using the Rubik's Cube, beginners should first remember: up, right, down, right and anti-left. This step is used to swap the positions of small squares on two adjacent vertices.

Up, left, down, down, this step is used to exchange the positions of the small squares on the top two diagonal vertices.

Up, left down, left up, Zuo Zuo down, Zuo Zuo. This step is to rotate the angles of the small squares on the top three vertices by 120 degrees.

Up, left, left, left, right, down, right, down, right, this step is to exchange the small squares in the middle of the three sides in turn, while ensuring that all other small squares do not move.

While remembering these formulas, you should practice more at ordinary times. We must have an intuitive understanding of the Rubik's Cube, remember the directions of six faces, come up with ways to restore the Rubik's Cube and play it well.
