3 order Rubik s Cube gameplay, 3 order Rubik s Cube advanced gameplay

It's been a long time since I've spelled a Rubik's Cube, and today someone suddenly asked, so let's talk about it. (My best time is 50 seconds).

The first layer: The first layer is self-taught, and it is very simple. Let's not talk about it.

The first layer and the first side are put together synchronously.

Second layer: Place the full side side down. Then align the middle of the second layer with the first layer to form a small inverted T-shape. Realign the middle of the third layer.

If the front is blue, the left is green, and the right is yellow. At this time.

The middle of the second and third layers is blue. The third layer is green above.

Use the left-shift formula: up-left-up+left+up+front+up-front-(up, down, left, right, front and back.) + refers to 90 degrees clockwise, - is the opposite, 2 fingers to 180 degrees).

If the front is blue, the left is green, and the right is yellow. At this time.

The middle of the second and third layers is blue. The third layer is yellow on top.

Use the right-shift formula: Up+Right+Up-Right-Up-Front-Up+Front+

When the second layer appears, the right side of the front is yellow. The second layer on the right and the left are blue with shortcut formulas.

Quick formula: Right + Up 2 Right - Up + Right + Up 2 Right - Up + Front - Up - Front + +

And so on, put the second layer together.

Third layer: After the second layer is put together. There will be 4 situations on the top surface (we will spell the word "ten" on the top surface next):

1.There is only one top color in the middle. Use the cross formula over and over again. Appearance 2

2.The top surface forms a top color. Turn the top face to turn the line into a vertical line. Use the cross formula again. Appearance 3

3.The top surface forms a right angle. One side up, the other side down. Use the cross formula again. Appearance 4

4.A "ten" word (needless to say in this case).

Cross formula: right-up-front-up+front+right+

Then the color. (The third layer is the same color as the side).

Color matching formula: right-up-right + up-right-top 2 right + top 2 Effect: The color of the top layer on the left remains unchanged. The remaining three sides of the middle color rotate counterclockwise.

until the color is the same in the middle of the four sides.

After the top cross is put together. Here are three formulas to spell out the top surface:

1.Left + Right - Up - Right + Up + Left - Up - Right - Up + Right + Effect: The top right corner of the top surface does not move. The lower right corner flips to the top of the upper left corner, the upper left corner flips back to the bottom left corner, and the lower left corner pans to the lower right corner.

2.Front + Right - Front + Left 2 Front - Right + Front + Left 2 Front 2 Effect: The top right corner of the top surface does not move. The rest of the triangles are translated counterclockwise for one round.

3.Left + Right + Up 2 Left - Right - Back + Front + Up 2 Back - Front - Effect: It's hard to say, just use it once after the six sides are good (this is also a shortcut formula).

Here is the most popular advanced gameplay of the third-order Rubik's Cube - the Rapid Recovery Method (CFOP). The formulas in this CFOP tutorial are somewhat long and very demanding on the technique, so you can appreciate the subtlety of the technique in the process of practicing. If you haven't learned how to restore it simply, you can learn how to get started with the Rubik's Cube before learning this tutorial.

This method is broadly divided into four steps:

1. Cross: There are 12 basic formulas, but several positions are relatively fixed.

2. F2L: When you first start learning F2L, you can first master the 3 basic rules and then study the principles of F2L, and then gradually memorize all the other 27 formulas.

3. OLL: There are 57 formulas here, so it is more difficult to memorize, but it is easier to confuse the ones that can be compared with the memory as much as possible, and find some obvious differences between them, as long as you practice more, you can quickly distinguish them.

4. PLL: There are only 21 formulas here, but the difficulty coefficient of several PLL techniques is very high, and more practice is required to achieve a satisfactory time to complete. (The figure below is a four-step analysis diagram).

The following is a general formula for the Rapid Restoration Method (CFOP) and the corresponding analytical diagrams

r u r' u'）（r' f）（r2 u' r' u'）（r u r' f'）、u z（u' r d'）（r2 u r' u' r2 u）z'（r u'）u’、（r u r'f'）（r u r'u'）（r'f r2 u'r'u'）、(r2 u' r' u') (r u r u ) r u' r )、r u r u2 ) r' l'u r u' l ) u2 r2 )

Personally, I think you can learn CFOP within 1 minute of playing the Rubik's Cube

If you're starting with the layer-first approach, then it's actually a simplified version of CFOP.

The formulas of the layer-first method are all extracted from the most basic part of the 119 formulas in CFOP.

Then break down the steps to simplify the situation of the Rubik's Cube to make it easy for novices to learn

Overall, the limitations are very large, and it is not easy to play within 30!!

CFOP method is an advanced version of the layer-first method, and it is now the most mainstream rapid reduction method in the world! (Not one!!) ）

CFOP seems more difficult than it does for many newbies, as it contains 119 formulas for standard conditions (standard conditions are the most basic).

Each formula is solved for a situation, so the overall certainty and number of steps are improved!

CFOP generally learns 119 formulas for standard conditions: cross, no formula, 41 for f2l, 57 for oll, and 21 for pll.

And then when you're sub20, you're ready to start learning all sorts of advanced content!

For example: non-standard, empty slot, four-way, X-cross, etc.

Of course, the primary gameplay is not only layer first, but also corner first, face first, color first, and bridge (in fact, this can be regarded as advanced gameplay!). And so on and so forth.

If you're learning something other than layer-first, it's a good idea to take the time to learn layer-first first, and then move on to CFOP to help you understand.

Personal hand-to-hand play is never copied!!

Advanced gameplay, in fact, to put it bluntly, is to memorize formulas, if you have time, you can still do it, but the hand speed can't be improved, and there's no way.

The spelling of the third-order Rubik's Cube is as follows:

1. Select one side of the Rubik's Cube as the bottom layer and make a cross structure on the bottom surface.

2. Restore the corner blocks of the bottom layer, r, u, r'、u'Do it three times in a row.

3. The middle edge is homeless, (u, r, u'、r'）、u'、f'、f、u）。

4. Set up a cross on the top floor, pay attention to the formula, and don't turn the wrong direction. f（u、r、u'、r'）f'Morning call.

5. First learn to judge the direction of the corner block, and then adjust the direction of the top corner block to make the color of the top surface bright. （r'、u）（l、u'）（r、u）（l'、u'）。

6. Finally, restore the position of the top corner block. l、f【（r'、u）、（l、u'）、r、u）、（l'、u）f'】l'。

Spelling the third-order Rubik's Cube needs to use the layer first method, the layer first method of the restoration step has 6 steps, several steps are used in the formula, the formula r, l, u, d, f, b respectively refers to the right, left, top (top), bottom (bottom), positive (front), back (back) layer, code suffix (') or (i) indicates a 90° counterclockwise rotation, and the layer code suffix (2) represents a 180° clockwise rotation.

The Rubik's Cube, also known as Rubik Cube, was first invented in 1974 by Professor Erno Rubick of the Budapest School of Architecture, Hungary. The Rubik's Cube has a variety of gameplay methods such as racing, blind twisting, and single twisting, and its popularity has endured, and it is one of the most popular intellectual games with large and small events held every year.

Tick up and down: rur'u'or lul'u'

After the above steps are completed, the following four situations will generally occur (point, one, 7, ten).

Solution: The center of the yellow noodles is pointed, we pick up the edges (the top is not yellow), and then reinstall it so that the yellow is facing up. It is divided into 7 shapes, 10 shapes, 1 shape, and point shapes.

Formation: Below.

22。Small fish formula 2 case.

After. 2. The last four left all use the small fish formula 1.

In the above picture, the two corner blocks are not yellow facing up, at this time we need to move the entire Rubik's cube so that the side of one of the corner blocks is facing back (relative to the chest), and adjust the position of the Rubik's cube (2 back) as shown below

Formed: As shown in the picture above, find the left side of the yellow side and place it. Now I make 1 male small fish.

25.All cross-shaped mockups.

This kind of cross-shaped face is the wrong Rubik's cube. Note that there are two corner blocks with the sides yellow on one side.

32.There is not a single border of the same color at both corners (1 in 6 probability) - first the yellow is facing forward, the others are arbitrary.

- After that, the form of the 31 will be formed.

33.Adjust the order of the top layer of edges and blocks to restore the Rubik's Cube.

Repeat 31 32 to form four sides of two roles and one to. Now the prism has not been done well.

331.Make three counterclockwise rotations.

Solution: First: Let the yellow side face up, and the freshly made side facing forward (chest) 332Make three clockwise rotations.

Treatment: First: Yellow side up, let the finished side be placed on the right.

333, cross swap.

First of all: the yellow side is facing up, and the other sides are free.

Secondly: do it again with 331 or 332 to form 331 or 332.

334, two side exchanges.

The gameplay of the third-order Rubik's Cube is as follows:

First, put the white block in the middle, face the top, and then make a white cross at the top, that is, the positions of the other colors should correspond to each other. Then place the white corner blocks, then let the middle edge blocks back into place, turn the white side downwards to find the red and green edge blocks. If the red and green edge blocks are on the top layer, rotate the top layer clockwise until the edge blocks are the same as the previous one.

If the red and green edge blocks are in the middle layer, but the position or color is wrong, make the red and green edge blocks in the front right position first.

Rotate again in one of the following orders, the top layer should be yellow, and the side blocks should be adjusted upwards to make a yellow cross. If you press the mantra once and the yellow cross does not appear on the top layer, you can repeat the mantra until it appears. Then adjust the yellow corner blocks of the Rubik's Cube around the cross, and there will be a misalignment between the yellow blocks and the colors of the sides.

According to the formula, position the yellow blocks at the four corners, and then adjust the color blocks on the edges to the corresponding positions, and it will be complete.

There are many ways to reduce the third-order Rubik's Cube, among which the "layer-first method" is the most suitable method for beginners to master. A third-order Rubik's cube, "from top to bottom" can be understood as "top", "middle", "bottom", the so-called "layer first" is layer by layer reduction. The third-order Rubik's Cube single world record is held by China's Du Yusheng in seconds, and the average world record is held by Poland's Tymon Kolasiński and the United States' Max Park.

1. The six sides of the Rubik's Cube are divided into six faces: upper, lower, left, right, front and back, which are represented by the letters U, D, L, R, F and B, and the bottom layer, middle layer, and top layer.

2. Establish a datum bottom, such as using red as the datum bottom, that is, the middle one is red as the bottom surface.

3. After selecting the bottom surface, turn the bottom surface into a cross shape. Turn the front and back sides to the same color as the bottom layer corresponding to the red cross on the bottom.

4. Turn the red corner corresponding to the bottom surface to the front right, and use the formula to turn it to the bottom color. The same goes for the other corners, turning the bottom surface into one color.

5. When rotating the middle layer, first turn the color of the upper layer and the middle layer to the same, turn it to the right or left side, and then use the formula five straight and four reverse or five reverse and four straight, and the other angles are the same, and the middle layer can be restored.

6. The top layer is also the least good layer, first use the formula to turn the top surface into a cross shape, if you do not succeed in trying several times, as long as the cross appears, you can restore the top layer several times.

7. Restore the four corners and four sides of the top layer, turn one side and one side and turn away to yourself, and use the remaining three sides with a formula, use a few more times to turn the side well, pair one of the corners, and then turn the whole Rubik's Cube to yourself 90 °, use the formula to turn the corners well, and the whole Rubik's Cube will be completely restored.

The gameplay of the third-order Rubik's Cube is as follows:

1. The formula letter means that in front of the F-front, the side you are facing behind the B-back, the back is facing you, (you can't see) the side R-right, the left side of the L-Left, the right side, the U-up, the top surface, the D-down, the bottom of the Rubik's Cube, the edges, corners and the center block, the edges are with two colors, the corner block is with three colors, the center block is the most central block on the surface, fixed.

2. Introduction to the restoration process of the Rubik's cube Establish the bottom cross Restore the first layer Restore the second layer of edges Establish the top layer cross Build the top layer complete top layer Restore the top layer corner blocks Restore the top layer of the edge blocks (restore the Rubik's Cube).

3. In the step of constructing the top cross floret, you need to put the four edged blocks with white on the top surface with the yellow center block first. To complete the bottom cross, you need to turn the small flower edges to the bottom layer, and you need to make the four edges of the bottom layer in the correct position and color.

4. To complete the restoration of the bottom layer, it is necessary to put the four corner blocks with white color into the bottom layer to complete the bottom layer, and the position and direction of the corner blocks need to be correct. To complete the return of the edges of the second layer, the four edges of the second layer need to be correct, and the four edges without the yellow color of the top layer need to be restored in turn.

5. In the step of restoring the third layer of the top layer cross, there will be four situations, you need to adjust the direction of the four top layer edges to build a yellow cross, and when building the yellow cross, you do not need to look at the position of the top layer of the edges, nor do you need to look at the top layer corner blocks.
