X-Parity

(Published on 19. February 2021, 17:31 by LKegel)

Normal sudoku rules apply. Furthermore, clues on top and to the left of the grid give the amount of even numbers in the first X cells from that position, where X is the first cell seen from that position. Clues below and to the right of the grid do the same, but with respect to odd digits. This is emphasized by the E and O in the corners.

Question marks denote an unknown value, and can be different per question mark (basically, they serve the aesthetic purpose of avoiding ugly gaps in the clues :) )
