The white square is solid. This is obvious. If you can't see which one can jump, you can jump directly by pressing the space to see which one is solid (that is, white square).
It is recommended to jump from the right to the second floor (the second white solid square from right to left).
Jump to the third floor on the right (the first piece of white from right to left)
Jump to the left of the fourth floor (third white from right to left)
Jump to the fifth floor on the right (the first piece of white from right to left)
Jump to the left on the sixth floor (from right to left, the fourth and fifth blocks)
Jump to the left of the seventh floor (the leftmost white one)
Jump forward on the eighth floor. The white one in front of you. )
Go to the top floor. Then look down. Skip the white one.
I hope this helps.
