The following puzzle is the next part of a particular small project from mine, which mixes some of the hybrid ideas between latin square/sudoku and different shading genres; and the very first genre coming into my mind that I haven't done in a while is actually Yin Yang.


Yin Yang is the one genre I've always been intrigued to set an engaging hybrid with and I accomplished it well with the first entry of it. Since the first part used inclusion-type arrow, this next part here will tackle on exclusion-type arrow.

The setting process of this was actually not so linear overall since honestly, I've been very busy in real life - including working around my mental health for a while, and the entire process kept being interrupted a lot here. At the end I felt like I might've created something even quite crazier than the first part there.

This is easily one of the most consistent and rewarding puzzles I've ever set and I'd even thought of some reconsideration at one point, but shoutout to my friend Calvinball for testing this one and the convincing feedback that led me to this final decision.
Let's see how this goes:


Rules:

- Normal Sudoku rules apply: every row, column and 3x3 box contain digits from 1 to 9 each once.

- Yin Yang: Divide the entire 9x9 grid into two regions of cells with two different shading colors so that each region forms a single orthogonally connected area, and no 2x2 area in the grid may be covered by a single region.

- A digit in a cell with arrow[s] is equal to the combined amount of cells in the indicated direction[s] that share the OPPOSITE color as that arrow cell.

- A white dot implies that within the four cells surrounding that dot, the sum of the cells belong to one color must be the same value as the sum of the cells belong to the other color. Not all white dots are given.
