Although it's more of a Build-Your-Own Irregular, this Yin-Yang Chaos Construction was inspired by Jesper!
- Every digit from 1 to 9 appears once in every row, column, and region. 9 regions are to be determined. Every region is a set of 9 orthogonally connected cells.
- Shade some cells, so these conditions are all fulfilled:
-- All shaded cells are orthogonally connected.
-- All unshaded cells are orthogonally connected.
-- No 2x2 area is fully shaded or fully unshaded.
-- Each region is either fully shaded or fully unshaded.
- Digits in cells with one or more arrows are equal to the total number of shaded cells that appear in the indicated directions combined (excluding itself).
- Not all possible arrows or arrow combinations are given.
Hope you enjoy the puzzle! 😄 - Any feedback or comments welcome!
Solution code: Row 7 (left to right) with dashes for region borders. (e.g. 123-4-56-789)

really enjoyed that. the logic was challenging to find, but rewarding once you find it. thanks for setting.

Brilliant puzzle! It was very hard for me. I don’t know if I followed the correct logic path because I had to get around quite convoluted logics but managed to nibble away bit by bit into the puzzle.
The end image looks like the lion on Sri Lankan flag :)

I tested this puzzle back in September. I recall that it was a really fun solve!

Enjoyed testing this, some really unusual logic. And not too difficult.
