Parity confusion

I hope you enjoy the puzzle!


Normal sudoku rules apply.

Digits within cells with large white circles show how many odd or even digits are in the surrounding 9 cells (including the cell itself). It is up to the solver to determine if the circle refers to odds or evens. ALL possible circles are given.

Digits in cages must not repeat and must be either all odds or all evens.

Cells separated by a white dot must contain consecutive digits. Not all possible dots are given.

Solve online: CTC, f-puzzles

Example: A cell with a circle with 3 in it, must have exactly 3 odd digits or exactly 3 even digits in the surrounding cells (or both if the cell is on the edge of the grid). A cell without a circle with 3 in it cannot have exactly 3 odd digits or exactly 3 even digits in the surrounding cells.

Lösungscode: Row 4 digits from left to right.

Do all circles refer to either odd or even? Or can it be different per circle?
