Fully Scrubbed
(Published on 11. May 2024, 19:42 by timotab)
- 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.

Bravo! Three stars based on the time it takes, but honestly more like two for each step along the way

This has to be one of the most unique yin-yang puzzles I've solved. What amazing setting!

Maybe I'm just a sucker for Yin Yang Sudoku hybrids where clues types perform multiple roles, but this whole series up to now has been very enjoyable for me to solve!

Best one in the series for sure.

@Schesam This puzzle is titled this way because the others in the series with largely the same rule set all have a cleaning themed name. No meta-hint was intended.

While solving and rereading the Title i got why you named it like that. But i didnt use that Knowledge and waited, till the Puzzle resolved it itself. Beautiful

Very nice ruleset. Fluent solve. Like all YY it takes a little time to solve but it's very satisfying.
Well done timotab.
