Double Counting [Duality]
(Eingestellt am 17. Oktober 2024, 16:42 Uhr von 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 in circles also indicate how many circles in the puzzle that contain that digit.

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