Killer in the Mirror - Parity mirror, killer sudoku
(Published on 14. August 2023, 12:48 by Mr.Menace)
- Normal sudoku rules apply.
- Killer sudoku rules apply. Digits in a cage add up to the cage total mentioned in the cage. Digits may not repeat in a cage.
- The diagonal from r1c1 to r9c9 acts as a parity mirror. Each cell has the same parity as the cell reflected in the mirror, i.e. if r2c6 is even, r6c2 is also even.
- Cells marked with a grey square contain even digits.
The puzzle is also available on Penpa and Sudokupad. Have fun solving!
Solution code: 5th row and 5th column

Are the gray squares also even, or is they just decoration?

They are indeed even. I will add it to the rules.
Thanks for pointing out!
