My second addition to the modulo series. I thought it would nicely interact with yin yang shading. Have fun and leave a comment.

• Modulo Cages
• Modulo Yin Yang
• Fun Modulo 4
• Modulo Yin Yang 2

Normal sudoku rules apply.

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

Modulo 2 shading: The value of digits on shaded cells count modulo 2, meaning that even digits have the value 0, and odd digits the value 1.

Arrows: VALUES along an arrow must sum to the VALUE in the circle from which the arrow emerges. Digits and values may repeat along arrows if allowed by other rules.

Kropki pairs: The VALUES of digits in cells separated by a black dot are in a 2:1 ratio. The VALUES of digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.

Additionally cells separated by WHITE dots are shaded differently.

Here is a small example to clairify the rules:
