Parity Caverns
(Published on 20. October 2023, 21:26 by yttrio)
Rules:
Normal Sudoku rules apply.
Digits in a given circle are odd. Digits in a given square are even.
Additionally, all digits in cells with given circles/squares count the number of cells which that cell sees in all orthogonal directions (including itself) of the same parity as itself (odd vs. even). Digits of opposite parity block the view.
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Play the example 6x6 in f-puzzles.
Play the example 6x6 in SudokuPad.
Solution code: Row 4
