Hint 1 (2016-04-23 12:00Z)
Currently the sudoku clues are UNMATCHED, and there are 7 possible "solutions"
Hint 2 (2016-04-24 23:15Z)
I was going to just give the hint "Where do 1 across and 1 down go?", but realised I had made an error - I just edited the numbers of all the clues to be one greater than listed except 1 across (I had edited these on the day I posted due to comments about crossword numbering convention). This hint is therefore even greater (but it's my own fault of course!). Now...
"Where do 1 across and 2 down go?"
Hint 3 (2016-04-25 14:00Z)
What could $\text{clues}$ and $\text{remainder}$ be in the equation $\text{clues} = \mathcal f(\text{clues}, \text{remainder})$?
