Hello,
Can anyone explain why the answer, "457389261" for 11A is not true? I feel that there are two correct sets of answer for that sudoku. Both "457389261" and "487359261" are correct.
Thanks

Dear Torontonian Zekeriya,

in your solution there is created new perfect square in second column between cells [2,2] and [3,2] = 25!
But there is no grey square. All grey squares are already marked and that's why your solution can't be correct.

I hope that my explanation is understandable.

Best,
Karel (Admin)
