The logical solution to level 24 is worth learning.
In this level, I summarized the previous levels and roughly guessed what it would look like when I was almost successful in the end. Then I transformed the problem into the path problem of the small white block, and went straight to the optimal solution (minimum number of steps). I guessed that the optimal solution would be The number of steps in the solution should not be many, so we can deduce the solution of up → up → return to the bottom → right → up (forming central symmetry) → rotation.
