Normal sudoku rules apply.
Place the digits 1-9 in every row, column and 3x3 box.
Uni-parity lines:
A blue line only contains even digits.
An orange line only contains odd digits.
Disjoint groups:
Cells with the same relative position in their 3x3 box must be different.
(Example: r1c1 and r4c4 must be different)
Kropki:
Digits connected by a white dot must be consecutive.
Digits connected by a black dot must be of 1:2 ratio.
Solution code: Enter row 1 and 9.

Very cool, the disjoint group constraint makes this puzzle more difficult than it first seemed. '-'

I really enjoyed this thanks! The logic flows nicely and the disjoint groups are just tricky enough to make this somewhat hard.
