I found two solutions, one of them being "correct".
The other merely switches 2 digits column-wise, or row-wise.

Did the judges not see this?

bartus,

What is the alternate solution that you found? I just resolved the problem, and I came to a single solution again. I certainly may have made a mistake, but I'm pretty sure that my logic was sound.

Thanks,

Hey, I also checked, and it still seemed unique to me.

Never mind. I'm sooo stoooooopid (sometimes

)

I forgot the most basic constraint: "such that no two horizontally, vertically or diagonally adjacent cells contain a digit."

I checked and double checked my 'solutions' before deciding to post this. But I didn't check the actual constraints for this puzzle type...
Duh....

No worries, I've done the same thing too many times

Glad to see it was a misunderstanding, and not a duplicate answer. That would be bad
