my mother gave me a book of puzzles and this is one of them. But unfortunately the book doesn't have instructions for it.

How do you play it?:confused:

Every 3x3 square should have the numbers 1-9 in them. Additionally every column and row overall should have the numbers 1-9 in them.

Hopefully that's what you're talking about. :wave: I haven't played sudokus since elementary school but they were pretty fun.
