maybe the rule could be more specific, as in the digits 1-9 (each one time)
maybe I'm wrong, but I thought if it have 2 of the same digit its no longer a "true" magic square :)

@NurglesGift : I know that logic about Magic Squares. But are you sure this is 100% correct in irregular sudokus? As there could be double digits in a 3x3 square, maybe there are other Magic Squasres possible???

Thank you everyone!

Well you can find many places that explain Magic squares. but to make it simple. 5 must always be in the middle, the 4 corners must always be even. from that the puzzle will give you a 2-4 pair and a 9 in the middle of them.

It is so satisfying (and such a rarity) to solve a non-trivial sudoku without a single pencil mark. From fully colored straight to digits!
