A great puzzle, you don’t need to check it, it is already very good. If some prompt numbers are removed, it may become very difficult to solve them through normal logic.

The given number on the board should be the only solution that controls it. The number 6 is redundant, and the number 1/3/9 only needs to keep one of them.
