Clashing Chameleons
(Published on 1. May 2025, 18:24 by the_cogito)
Rules:
- Normal Sudoku rules apply.
- Shade the boundary between adjacent digits if and only if they sum to an even number. Shaded boundaries must divide the grid into exactly 2 regions. There may be shaded boundaries that lie within a region without fully dividing it, as allowed by other rules.
- A digit in a cell with one or more arrows indicates the total number of shaded boundaries in the directions of all arrows combined.

We need to see more puzzles exploiting these ideas. The symmetry break in this one is exquisite.

Awesome puzzle! Adding this to my favorites. It was a joy discovering the consequences of the ruleset and figuring out how to apply them to solve the puzzle.
