Discriminating discrepancies
(Published on 23. August 2025, 05:30 by NicoD)
Rules
Normal sudoku rules apply.
Shade some cells so that all shaded cells are orthogonally connected, and all unshaded cells are orthogonally connected. No 2x2 area may be completely shaded or unshaded.
A shaded cell's value counts as its digit plus one, and an unshaded cell's value counts as its digit minus one.
Within a cage, digits must not repeat and their values sum to the small number in the top left corner.
Solution code: Row 9

I have solved at least 20 of your puzzles, and some of those I have had to guess at times. This puzzle is your best puzzle. It's difficult to see the break in, but when you find it the next steps open up the puzzle. And it's still tricky to the end. Thanks!

Loved how the yin-yang and killer logic each drove each other. Fun puzzle!
