Normal Sudoku, Region Sum Lines, and Even/Odd rules apply;
Region Sum: on each blue line, the sum of all cells within a region is the same across all regions the line passes through;
Odd/Even: cells on a shaded circle are odd and cells on a shaded square are even.
I suppose this is a sort of sequel to 'One Loose Thread' . (which I am still very proud of). The solve path here is a bit longer/more gradual.
Solution code: row 1 (left to right) followed by row 9 (left to right)
