Counting Oddly
(Published on 13. July 2026, 07:28 by timotab)
- Normal Sudoku Rules Apply: Place the digits 1 to 9 once each in every row, column, and box.
- Digits in cages do not repeat, and must sum to the value in the top left corner of the cage.
- Clues in white circles indicate the total number of odd digits that border (orthogonally or diagonally) the two cells immediately touching the circle, not including the two cells themselves.
As well as setting puzzles, I also solve puzzles on YouTube. Please check it out!
Solution code: Column 1

I am not sure which was harder. Colouring the grid or solving for the numbers.
¯_(ツ)_/¯

That was a delightful puzzle! It took me several minutes to see the trick to start but once it got rolling it was a smooth ride.
