How to play the pyramid cube and what is the pyramid cube formula

Change the position, color direction.

The pyramid is simple.

It's OK to go to the Rubik's Cube station to learn the inversion formula of color direction.

The characteristic of monochrome zongzi is that only the shape is considered, and the color is not considered, so the structure is simplified a lot. There are only three categories that need to be dealt with:

1。The position of the corner blocks.

2。The direction of the edge.

3。The direction of the center.

The first three rankings are not necessarily in order, but according to my thinking, it is more convenient and faster to use the angle first method, so three sets of formulas are designed for the three situations that need to be dealt with.

These formulas cannot be said to have been designed by me, they are all adjusted on the basis of the existing formulas, and simplified according to the situation of zongzi.

Step 1: The octagonal dumplings return to their positions.

Since there is no need to consider the direction, the homing formula can be simplified to four steps, and in practice, it is just a matter of exchanging large and small corner blocks.

This is a relatively common situation that needs to be swapped, and the formula is [ru'r'u], although the formula is not just the exchange of these two corner blocks, but on this monochrome zongzi that does not consider the direction, the effect is that the size of the two corner blocks are reversed.

Be sure to clarify the concept of space, the finished Zongzi Rubik's Cube, the large and small corner blocks are alternate with each other, taking the third-order ordinary hexahedral Rubik's Cube as an example, if the big corner blocks are in the position of the left front and right back of the bottom layer, then the two big corner blocks on the top layer are the left back and right front.

This is done by setting up the 8 corners in the correct position.

Step 2: Flip the edge.

This formula can flip two adjacent edges, if both adjacent edges are in the wrong direction, it can be done in one go, and if one of them is right, there is no practical value in doing this.

According to this formula, if there is a situation that the two adjacent edges that need to be swapped are not adjacent, you can turn each side to combine into adjacent edges and flip, or you can use this formula to "pass" the demand for flipping.

The formula operation is [(r'uru'2], as with the previous explanation, although the other pieces have also been swapped, but on the monochrome zongzi, the change that can be observed is between the two adjacent edges.

Step 3: Rotate the center.

If there is an error in the center direction, it must be an error of a 90-degree angle - because if it is a 180-degree angle, it cannot be observed.

This kind of error is more special, it will not appear on the ordinary third order, and this error occurs on the monochrome zongzi because there is an error in the combination of edges and corners of the entire Rubik's cube, and I like to use [r] to solve the formula'u'r'u'fuf], in fact, at this time, the first r' and r function exactly the same, and the last f and f'The effect is exactly the same, I listed this set of letters but I think it is easier to remember.

Using this formula, you can rotate the center of the top face (u) incorrectly, and if the center of each face is not correct, you can repeat it. Again, the formula operation does not only affect the central block, but the movement of the other blocks cannot be observed at all, so it can be ignored.

1. The pyramid cube formula has t'ltl'，r'trt'，rl'r'l，rtr'trtr', b for down, l for left, r for right, t for front.

2. Finally, when the bottom three edges are in place, the yellow one is on the left and the left-handed formula is used: lower left, lower right, upper left, upper right, and upper right, and yellow is in the right hand formula: lower right, lower left, upper right, upper left.

3. The basic composition of the pyramid cube has four small corners, four large corners, four corner blocks, and six edged blocks. The basic steps used in the restoration are small corners to large corners, corner block homing, completing the bottom layer, and finally all restoration.

4. The first step is to have a small corner to a big angle, first get a scrambled pyramid cube and then observe whether the colors of the four corner blocks are aligned with the small corners and the big horns, if not, you need to align the colors of the corner blocks, and the second step is to return the corner blocks to the place, and observe the color of the four corners facing up after placing the pyramid cube on the plane.

Note that the position of the pyramid corner blocks cannot be changed, and the color that one corner block does not have will not appear when the other three faces are restored.

5. Therefore, when rotating the Rubik's Cube, if there are three corner blocks with yellow sides on the left, right, and front three sides, the yellow corner blocks should be rotated to the bottom.

6. The third step is to return the three edges of the bottom layer to the position, observe what color the corner blocks of the second layer of yellow edges are opposed, if it is blue, the yellow side of the top layer of the corner blocks and the blue side of the bottom layer of the corner blocks should be rotated to one surface. If it's red, turn the red side and the yellow side to one face, and the green side will rotate in the same way.

At this time, adjust the left-hand formula or the right-hand formula according to the position of the yellow corner.

7. Finally, return the three edges of the upper layer, adjust the corner blocks of the upper layer, observe the other color of the blue edges, turn the yellow-red-green corners of the red blocks, make the left-handed formula by the left hand, and use the right-hand formula to complete the blue edges, so that all the edges are restored.

The formula for the Pyramid Cube is:1. Make one side first, adjust it, and form an inverted T shape.

2. Spell the second layer.

3. Draw a "cross" on the top layer.

4. Assemble the surface of the top layer of the third layer, regardless of the side of the third layer.

5. Adjust the four corners of the third layer.

6. Adjust the position of the third layer of side blocks to make the third layer completely home.

A tetrahedral shaped Rubik's Cube. Invented in 1970 by German scientist Professor Uwe Meffert, it was originally a model he used to study the energy of the pyramid, and in the process of research, he accidentally invented the pyramid cube.

There are four outer corner blocks, four inner corner blocks, and six edge blocks. Its color arrangement can be changed by rotation. The axis rotating block can be rotated without changing the state. 6 side blocks can be rotated freely. The four top blocks can rotate themselves independently of the others.

The specific method of the pyramid Rubik's cube restoration is to use a certain formula, plus the flexible use of fingers, to rotate the Rubik's Cube back and forth. Here's how:

Tool: A Rubik's Cube.

1. First of all, return the corner blocks of the pyramid cube to their positions, and then choose a random color to put the center blocks together.

2. If the yellow surface is selected as the bottom surface, then the surface corresponding to the corner block without yellow is the yellow bottom surface 3 to restore the yellow bottom surface, put the yellow bottom surface in the position of the bottom surface, and observe whether there is a yellow edge in the edge position of the upper corner block.

3. Next, restore a layer, after restoring the center block, there are only three color blocks left in the first layer without restoration, which is very simple, using the restoration skills of the third order Rubik's Cube layer, pay attention to the position of each color block.

4. After restoring a layer, you need to restore the center block of the entire Rubik's Cube, there are a total of 4 central blocks of the pyramid Rubik's Cube, and the center block of 3 4 is restored after the restoration of a layer, and there is still one difference between the second layer and the top layer, so that the diamond-shaped color of the top layer is consistent with the first layer, and you only need to rotate the second layer and the top layer.

5, turn up the left corner block, turn the upper corner block to the right, turn down the left corner block 6 when one side is spelled, choose the other side to start spelling the Rubik's Cube, this time continue to choose to spell the yellow side, and finally find that all the faces have been spelled.

Notes:

Don't use too much force when rotating the Rubik's Cube, otherwise it will be easy to break the Rubik's Cube, and you may also hurt your fingers, which will outweigh the losses.

The third-order Rubik's Cube of the square is difficult.

Just looking at all the changes, the third order is an astronomical number, and the triangle.

is much less. The triangular one is also called the "pyramid Rubik's cube", while the square one is the ancestor of the Rubik's cube, the third-order one. It takes time to learn the third step, the seven-step tutorial, and you also have to memorize formulas and judge various situations.

The pyramid has few changes, and it can be restored by luck. And it is simply impossible to recover by luck after the disruption of the third order.

The composition of the Rubik's Cube.

The third-order Rubik's Cube consists of a central axis connected to six central blocks and 20 blocks of different structures, which, when connected together, form a single unit, and either side can be rotated horizontally without affecting the other blocks.

Fourth-order Rubik's Cube. Compared with the third order, it is much more complicated, its composition is divided into two categories, one is a sphere in the center, and each outer number contains a small piece connected to the slide rail of the center ball, which will slide on the slide rail along the direction of force when moving. The second type is the fourth-order Rubik's cube with the axis as the core, which is very complex in composition, and there are many additional parts in addition to the central ball and peripheral blocks.

As a racing activity, the fourth-order Rubik's cube composed of the second type moves quickly and is not easy to get stuck in high-speed rotation.

Fifth-order Rubik's Cube. The composition is even more than the fourth-order Rubik's Cube. It takes a long time to invent a new high-level Rubik's cube, because it is necessary to consider not only the feasibility of the project, but also whether the cube can be stably used for rotation after being made by the cracked cherry fruit.

It is for this reason that the fifth-order Rubik's Cube is the highest level of the official Rubik's Cube, and its structure is not something that the average enthusiast can imagine.

The Pyramid Cube tutorial is as follows:1. The first step: the small angle is good for the big angle, as shown in the following figure

2. The second step: the corner block homing (adjust the color direction of each corner block), as shown in the following figure:

3. Step 3: Complete the bottom layer, as shown in the figure below

4. Step 4: Complete it all, as shown in the figure below

Tips & Tricks:The Golden Character Morning Carrying Tower Cube has four outer corner blocks, four inner corner blocks and six side blocks. Its color arrangement can be changed by rotation.

The axis rotating block can be rotated without changing the state. The 6 side blocks can be rotated freely. The four top blocks can rotate themselves independently of the others.

The four top blocks can be rotated with the axis rotation block, which will form a scrambled state with only the color of the side blocks changing, and since only 6 side blocks can confuse the Rubik's Cube restorer, the number of states is not as good as the second-order Rubik's Cube.

It is also easier to recover than the second-order Rubik's Cube, so don't be fooled by the complex appearance of the land core.

The Pyramid Cube is played by matching the colors of the blocks. The specific operation process is as follows:

Tools Ingredients: Prepare a pyramid cube.

1. The first vertical step: the small angle is good for the big angle, as shown in the figure below

2. The second step: the corner block homing (adjust the color direction of each corner block), as shown in the following figure:

3. Step 3: Complete the bottom layer, as shown in the figure below

4. Step 4: Complete it all, as shown in the figure below

Tricks to play the Pyramid Rubik's CubeThe Pyramid Cube has four outer corner blocks, four inner corner blocks, and six side blocks. Its color arrangement can be changed by rotation. The axis rotating block can be rotated without changing the state.

6 side blocks can be rotated freely. The four top blocks can rotate themselves independently of the others, and we can use this trick to slowly spell out the magic.

The four top blocks of the pyramid cube can follow the axis rotation block to rotate the shed, so that it will form a chaotic state with only the color of the side blocks, because only 6 side blocks can cause confusion to the Rubik's Cube restorer, because the number of states of the He clan is not as much as the second-order Rubik's Cube, and it is easier to recover than the second-order Rubik's Cube, so don't be confused by its complex appearance.
