Yin Yang killers
(Eingestellt am 22. März 2026, 21:07 Uhr von Killer Joe)
Hello.
Normal Sudoku rules apply.
Yin-Yang shading:
Color the grid using two colors such that:
Each color forms a single orthogonally connected region and no 2×2 block of cells is entirely one color.
The digits along each line sum to the same total.
Along each line, the Yin-Yang coloring separates odd and even digits; that is, all odd digits on a line are one color and all even digits are the other color.
Digits separated by a white dot are consecutive.
Have fun.
Lösungscode: Row 9, first 6 digits

This was fun! Thänk you! This was my first 3*. But it wasn’t hard for me. Maybe this is more a 2* or i‘m getting better haha

Enjoyed briefly thinking I had hopelessly broken the puzzle within the first minute or two.

Very lovely! One of my favorite of the last many I’ve done.

Having the polarity not stay constant across the entire YY threw me a few times. Luckily, a bit of YY knowledge led me to figuring out the line sum very quickly, and after that was a pretty steady and fun solve. It's nice when the two constraints play off each other, rather than filling most of the YY out and then going back for sums, or vice versa.

Very nice flow, some cool logic in there that makes the solve pretty quick if you spot it, but also very satisfying.

Beautiful puzzle! Important for future solvers: the odd/even coloring can change per line. The rules are clear about that, but it needs careful reading. Thanks!

Great puzzle! This may be odd to say, but I really like the yin-yang pattern that results here - it feels "rare" :)
