Traditional Third-Order Rubik's Cube and mirror cube

Generally, you have to play the traditional third-order Rubik's Cube first. mirror cube and the traditional third-order Rubik's Cube are restored in exactly the same way, except that the third-order Rubik's Cube looks at the colors, while mirror cube looks at the shapes (length, width and thickness). It is difficult to play at first, but it is still easy to restore as long as you master the skills. I restore the thinnest cube as the bottom layer first. I feel that mirror cube is more fun, and you will see strange shapes in the process of restoration.
