- 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.

Another nice break-in. The diamond/cage constraints work really well with Yin Yang. Great puzzle.

Agreed with the other comments. Flowed super nice but felt a little easier (but could be because I've done the first two before this)

+1 to yttrio's comment. The challenge is now to make a puzzle with a bit lesser dots and cages. Come on timotab, keep the good work going on.

Maybe my brain has now just gotten a bit more used to this rule set, but this one felt particularly smooth to solve. For me, all the deductions flowed really well!
