Vlad the Impaler - Parity mirror, killer sudoku
(Published on 19. August 2023, 08:14 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.
The puzzle is also available on Penpa and Sudokupad. Have fun solving!
Solution code: 5th row and 5th column

The CTC version has an incorrect solution entered for the checker.
Quite fun, took quite some colouring to get the first definite parity of a cell, flowed smoothly after that.

Much harder than I expected this to be. Excellent logic.
