Dishes Washed

- Normal Sudoku rules apply
- Yin-Yang: Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area is fully shaded or unshaded.
- Digits may not repeat in cages, and must sum to the value in the top left corner of the cage, if given.
- Cage totals indicate how many cells of the same colour (shaded or unshaded) are seen orthogonally from the position of the cell marked with a diamond in that cage, including itself. The 'other' colour blocks vision.
- Cells separated by a white dot are consecutive. Cells separated by a black dot are in a 1:2 ratio
- All dots lie on the border between the shaded and unshaded regions.

Fun puzzle! Difficult enough to require some thinking, but I never felt stuck either

Really great puzzle! Rather tough, probably the hardest f the series so far, but also one of the best of the series. Lots of really interesting deductions.

I love ying yang puzzles! This one I found quite difficult midgame. I'll admit at one point I just took one possibility nd ran with it, it turned out to be the right one but it was mere chance. Thanks for the puzzle!
EDIT: I did all the rest of your series, super enjoyable, thank you so much!

Great puzzle! Definitely the hardest in the series so far for me, but nothing unfair. This one had some particularly interesting logic sprinkled throughout the solve.
