Parity Party XXVIII, "Party Mirror"
(Published on 30. March 2023, 13:57 by glum_hippo)
Normal Sudoku rules apply. Fill each row, column, and box with the digits 1-9.
Clues along the edge of the grid are Parity Party clues. They indicate the sum of the digits seen from that standpoint, up to and including the first even digit, OR up to and including the first odd digit. A clue less than 10 might just equal the first seen digit (i.e., the sum of zero evens and one odd, or vice versa).
The odd/even parity of every cell is reflected across the puce diagonal. For example, R4C2 and R2C4 must have the same odd/even parity. (Thank you to zegres for popularizing this constraint!)
The digit in R9C2 is larger than R9C3, and R6C5 is less than R6C6.
Solve in F-puzzles or the CtC app.
Solution code: Column 8 (9 digits).
