Right inverse, up inverse, right shun, up inverse, right inverse, up inverse, and then right shun. Then there is our formula 2: first, left-handed, up-spin of the stool, left-handed, up-spin, and then left-handed. First, we reset the four tall building blocks on the white layer above, and then we need to prepare the quad-core building blocks on the middle layer.

Then the upper side block and the middle four-core block are reset together, and then the upper four corner blocks and the middle four side blocks are reset. Hot wheels is essentially a variant of the third-order Rubik's Cube. Although it is difficult to observe after being disturbed, it is still a third-order Rubik's cube. The recovery process is nothing more than adjusting the direction of the center block after adding the thickest one.

The Five Magic is another kind of Rubik's Cube with 12 axis. Although the recovery formula of the third-order Rubik's cube can be applied, it is difficult to apply. In addition, as a WCA competition, the advanced gameplay of the five demons transcends the third-order category. Personally, I think Rubik's Cube is more difficult and interesting.

Rubik's Cube, also called rubik Biqiao Li Cube, was originally a mechanical educational toy invented by Professor Ern Rubik of Budapest Institute of Architecture in 1974. There are many ways to play Rubik's Cube, such as racing, blind twisting and single twisting. And the popularity will not drop for a long time. Every year, large and small activities are held in the evening, which is one of the most popular intellectual games.

Bridge test method:

Roux method was invented by Gilles Roux in 2003. This is a simple and easy-to-learn method and can achieve good results. Step: step four; Formula number 9-42; Average reduction steps: about 50. The idea of restoration is to make a block of 1x2x3 on the left and a block of 1x2x3 on the right.

Leaving the top layer and the vertical middle layer free to rotate. The next step is to restore the direction and position of the top four corner blocks, and the last step is to restore the remaining six edge blocks and four center blocks only by rotating U and M. This method can be said to be the method with the least number of steps in fast rotation reset, but it is not suitable for the reset with the least number of steps because there are many rotations in M layer.
