As far as I know this ruleset is original, though I wouldn't be surprised if it's not - do let me know if you've seen it before! Either way, it should be fairly approachable!

Normal sudoku rules apply.
A digit, N, in a marked cell (green circle) describes how many of its neighbours are of the opposite parity to N. For example, a marked 3 would have exactly 3 even neighbours, and a marked 6 would have exactly 6 odd neighbours.
(For clarity: neighbours are orthogonal AND diagonal, and the grid does NOT loop around in any kind of cylinder or mobius strip. E.g. r1c5's neighbours are r1c4, r1c6, r2c4, r2c5 and r2c6)
Please remember to leave a rating! Thank you :)
Solution code: Row 5, left to right

Lovely parity puzzle, smooth flow and approachable.
The ruleset is familiar, though i can't say from where...

Thank you! Yeah it didn't seem outlandish enough to be completely original to be honest!!
