This was originally created for the Yin Yang Journey puzzle pack. Links to previous puzzles in the pack are below:

Rules:

Normal Sudoku rules apply.

Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.

The shaded cells act as a parity line: if two orthogonally connected cells are both shaded, then one of those digits must be odd and the other must be even.

A digit in a cell with an arrow counts the total number of shaded cells seen in the direction of the arrow (not counting the cell itself).
