I am sorry but I had to remove the previous puzzle... no matter the modifications, it always had multiple solutions :( This has an unique one, please forgive me.
This sudoku can be solved like a normal one; but numbers 1 and 2 never repeat in both diagonal directions like in the famous "N chess queens problem". Not hard to solve knowing that.
Solution code: 1ST row, then 2ND column

I was looking for a warm up queen sudoku and this came up. Perfect for who wants to learn the variant! :)
