Play in Sudokupad
Irregular sudoku rules apply.
Place the digits 1-9 in each row, column, and marked region.
Kropki dots: Black dots indicate cells with a 2:1 ratio. White dots indicate cells with consecutive digits.
Negative constraint: All dots within a region are given.
Note: If it occurs in the grid, within a region, a pair of 1-2 will be marked with either a black or white dot.
Solution code: Row 6

felt like a .5* with the negative constraint -- i wonder how much harder it is without it

Indeed, I didn't see the negative constraint, still very doable

I think you can solve it without using the negative constraint, but it's quite a bit harder.

Not so hard if you REMEMBER THE NEGATIVE CONSTRAINT. ;)
