Additionally, this clue is the sum of the digits in the 3x3 area centered on the cell with the clue. Digits can repeat in this area.
Solution code: Column 5

Nice two-part puzzle. The parity part flowed smoothly, but I also found the Sudoku part quite challenging. Thanks for sharing.

Great puzzle! I was very slow at one step in the solve, which lead to a long solve time. Therefore I rated it hard. Thank you
