Parity Fun 8

(Published on 11. January 2026, 09:34 by galium_odoratum)

This variation allowed surprisingly interesting deductions. It might be a bit harder than the average puzzle on this series, but hopefully still approachable. Have fun!

Normal Sudoku rules apply.

Even parity sandwich sums: Blue digits outside the grid indicate the sum of the digits sandwiched between the rightmost and leftmost even digit of the row/topmost and bottommost even digit of the column.

Odd parity sandwich sums: Orange digits outside the grid indicate the sum of the digits sandwiched between the rightmost and leftmost odd digit of the row/topmost and bottommost odd digit of the column.

Ambigous sandwich sums: Black digits outside need to be determined by the solver whether they are even or odd parity sandwich sums.

The SudokuPad link has the wrong sandwich sum on column 7, and the post here has the wrong one on row 7.
