Uh huh, every time the 3rd order Rubik s Cube reaches the end of the four pieces in the middle

Why is your Rubik's Cube this color scheme again?。。

Is the one to the left of yellow red? Is it right that yellow is orange?

If so, I'm starting to describe:

Red is facing itself, green is facing up, and yellow is on the right.

Turn the red layer 180°, the waist layer to the right 90°, the right hand yellow layer 90° upward, the waist layer to the right 90°, the right hand yellow layer to turn 90° upwards, the waist layer to the right 90°, the right hand yellow layer 180°, take a breath and continue, the waist layer to the left 90°, the right hand yellow layer up 90°, the waist layer to the left 90°, the yellow layer to the left 90°, the yellow layer to the left 90°, the waist layer to the left 90°, the waist layer to the left for the last time 90°, the right yellow layer to turn 180° last, the red layer to turn 180° to finish.

To memorize this set of movements, just see how many are repetitive movements, and organize them yourself to remember.

I'm sure you'll also encounter the situation where these two pieces of waist are facing the opposite direction. If that's the case, you don't need to turn 180 at the beginning and 180 at the end.

In fact, there are countless solutions to deal with such a situation, but the lack of regularity of the movements will cause difficulties in your memory. The solution I've provided you with is easy to remember, and you can still use it in the future, no matter how advanced you are.

The "Eight Immortals Guiding the Way" chapter in the Rubik's Cube Washing the Marrow Sutra can give you a clearer understanding of these finishing methods, but you need to understand some of the symbols of the expressions first.

In the second part of the restoration, the wrong block is replaced with the same formula.

The reason may be that the small pieces of 2 3 6 on the bottom surface of the surrounding area are not returned to the third step.

Methods of restoration:

Place the 2 corners where you want to swap positions on the right-hand side:

Right 90 counterclockwise - top 180 - right 90 clockwise - top 90 - right 90 - top 90 - left 90 - top 90 - top 90 - right 90 - top 90 - 90 - left 90, end.

For good crosses (as a whole, all of the side crosses are good), according to the following formula 3, for the top surface, 4 for the four corners.

Top surface, four corners of the formula four:

Equation 1, f (r u r' u'）f'

Equation 2, r' u2 r u r' u r

Equation 3, r b' r f2 r'b r f2 r2 equation 4, (r u' r）（u r u r）（u' r' u' r2）。

Step 1: The bottom edge is returned to position (also known as the bottom cross, the process of correct restoration of the bottom four edges).

Step 2: Bottom corner homing (restoring the four corner blocks of the first layer of the Rubik's Cube): Equation 2-1:

rur'Equation 2-2: (f'u'f) Step 3: Middle Ridge Homecoming (the step of restoring the four edges in the middle layer of the Rubik's Cube):

Equation 3-1: (u'f'uf）（uru'r'Equation 3-2: (uru'r'）（u'f'uf）

Step 4: The top edge position (also known as the top shelf cross, the top surface color of the top four edges is the same as the color of the top center block): Formula 4: f(rur'u'）f'

Step 5: Top Corner Position (the step in which the top color of the four top corners of the Rubik's Cube is adjusted to the top surface): Equation 5-1: R'u2rur'ur equation 5-2: u'ru'u'r'u'ru'r'

Step 6: Apex Corner Homing (the other two sides of the four vertex corners of the face position are the same color as the center block of the corresponding face): Equation 6: rb'rf2r'brf2r2

Step 7: Vertice homing (the color of the other side of the four vertex ridges that have been placed is the same color as the color of the center block of the other four faces): Equation 7: (ru'r）（urur）（u'r'u'r2）

There are two special cases for the final step of the Fourth-Order Rubik's Cube Raider:

1. Swap two opposing edge block groups.

2. Straighten a set of edges.

Fourth-Order Rubik's Cube: The official name in English is rubik's revenge, literally translates to "Rubik's Cube Revenge". It consists of 56 blocks, including 24 center blocks, 24 edge blocks, and 8 corner blocks.

There are a total of 7,401,196,841,564,901,869,874,093,974,498,574,336,000,000,000 variations, i.e. approximate species. The fourth-order Rubik's cube is generally reduced by the downgrade method.

I played the Rubik's Cube a few years ago, and now I still retain the restoration method of the Rubik's Cube, and I tried it again recently, but I didn't expect to remember it.

Found directly from the Internet, it seems relatively easy, you can try it, there are two special cases.

This kind of opposite exchange, two adjacent sides can also use this method, and after the exchange, it should be the case of three or four edges of the third order.

This is a flip of a two-sided block.

In fact, the only special case of the fifth-order Rubik's cube and the two special cases of the fourth-order Rubik's cube have not been remembered how to solve them, so every time I encounter them, I have to open the mobile phone to see the solution
