October 13 Difficult Kindly Sudoku
The puzzle seems to have two solutions that work. One of them has two 7's in the 21 cage at the lower left, but still gives credit for a solution. (One solution has 3-5-6-7 in that cage, the other 2-5-7-7.)

What do you mean by "still gives credit for a solution"?

(I'm trying to reproduce this, but failed so far :( )

When I put 2-5-7-7 in the 21 cage (and solve the rest of the puzzle), the whole thing turns green and says I solved the puzzle.

Ah, I see. It's not even flagging the double 7 as an error...

But presumably you don't get points for that solution, right?

Re: October 13 Difficult Kindly Sudoku
I'm not sure. I entered it both ways, got green on both, but I don't remember which way I submitted it first (and therefore got the points for).

You got points for the correct one

In any case, thanks for the report

Re: October 13 Difficult Kindly Sudoku
All fixed now, thanks again for reporting.

Uncovered a tricky bug in the code that checks the solution numbers:
the numbers sequence was seen as a large integer, so the comparison
failed for large puzzles, because the integer was too large (!)

(although I would have liked that in that case the comparison says the
numbers are not equal..)

Edit: amazingly, one minute after I put up the fix, someone submitted
a solution with the double 7! (which now wasn't accepted)
(because they loaded the page earlier, the "submission prevention"
wasn't in there yet)
