Monkey jumping off a building, very interesting name. Traditionally called ladder method, it actually means the same thing. The Robopard method we are talking about is actually 1 take the middle and then the upper right stairs to complete the Rubik's Cube.

There are only 1 basic solutions in the third-order magic square, and there are 8 forms, among which 7 forms are isomorphic solutions of 1 basic solutions, and the magic square itself has not changed.

Based on this, the stair method can be either going up stairs (left or right) or going down stairs (left or right), plus turning and going backwards.

But one thing, whether you choose to go up and down the stairs or so, the first number (usually starting from 1) must be placed in the middle of one side, and then you can take the stairs outside the Rubik's cube in the same way. When you meet a number, you will retreat to the opposite direction of the first counted edge and continue to take the stairs in the same way.

All odd Rubik's cubes can follow the above principles and be completed by ladder method.
