Rules
Normal sudoku rules apply.
The grid is covered in fog. Placing a correct digit will clear the fog from that cell and potentially from other cells somewhere in the grid. No guessing is required.
Box borders divide blue lines into segments with the same sum.
A digit in a yellow circle indicates the number of odd digits which appear along the attached line.
A digit in a blue square indicates the number of even digits which appear along the attached line.
Solution code: Row 6

The fog was very useful for directing focus--I think I would have gotten lost without it
