1. First, restore the bottom corner block: in this step, restore all the bottom four corner blocks.
2. When the white chess turns right, use the algorithm 1, turn right first, R-U-R2-R-U-R2.
3. Use algorithm 2 to move forward, first go to the front, F2-U2-F-U-F2-U2-F.
4. Repeat 4 corner blocks to make the bottom layer.
5. Then restore the top color: In this step, restore the color of the top surfaces of the four corner blocks.
6. In case 6, first use Formula 2-2; In other cases, first use formula 2-1; In other cases, the formula 2- 1 is used first.
7. Then restore the vertex block: If this happens, rotate the vertex block of the same color to the position facing you.
8. Use this algorithm again: R-B2-R-F2-R2-B-R-F2-R2, and you can complete the reduction.
Pocket cube, also known as pocket cube, mini cube, small cube and ice cube, is a 2×2×2 cube structure. There are only eight corner blocks in itself, and there are no squares with other structures. The structure is similar to the third-order Rubik's cube, which can be restored by the formula of restoring the third-order Rubik's cube.
Production patent
The earliest patent of the second-order Rubik's Cube was applied by Professor rubik Arne on March 29th, 1983/kloc-0. The U.S. patent number is 4378 1 17, which we used to call the second-order Rubik's cube with R structure.
Li Yu 1998 10/kloc-0 of Taiwan Province Eastsheen Company applied for another second-class patent on October 27th. American patent. 5,826,871.571,we are used to calling it the second-order Rubik's cube with Dongxin structure. Others have some second-order patents on patterns, such as Mickey head and K ball.
