Logic Masters Deutschland e.V.

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.
