Double Counting
(Published on 17. October 2024, 16:42 by timotab)
- Normal Sudoku rules apply: place the digits 1 to 9 in every row, column, and box, once each.
- A circle's neighbourhood includes the cell containing the circle, and any cell touching it (on an edge or corner). The digit in the circle is the number of cells in its neighbourhood that have the same odd-even parity as the circled digit.
- Digits cannot repeat in cages, and must sum to the value in the top left corner of the cage, if given.
- Digits in circles also indicate how many circles in the puzzle that contain that digit.
Solution code: Row 8, then column 8.

Please stop requiring 18 digit solution codes, it's overkill and hostile to mobile users
