- 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.

Tidied up rules, and changed some notation to be more standard. No substantive change in the puzzle

Nice puzzle. Not to hard if you are familiar with Yin-Yang.
