Normal sudoku rules apply.
Circled digits indicate how many of the up to 9 cells surrounding the circle (including itself) have the same parity (even/odd) as itself. Not all such circles are necessarily given.
If you enjoyed this puzzle and the logic of the circles indicating parity, check out my previous puzzle, Parity Hilarity:

not all such circles are given *or* not all such circles are necessarily given?

I fixed a mistake in the original upload (one of the circles was in the wrong position).

May you check the puzzle is somehow wrong.
