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
Perfect Square on Round 4
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,
