I realise this is a minor issue, and it really shouldn’t bother me, but why do they publish the answer to the previous days Sudoku in the paper? Surely you can just look at your answer and check. If it is right, it’s right!
Interestingly, unless the Sudoku is “well-formed”, there may be multiple solutions. If all the conditions are met then your answer is correct, even if it doesn’t match the published version. There is no such thing as a “better” answer.
Honestly, what a waste of space. Put another puzzle in instead.
