A Few Good Cages
(Published on 22. March 2025, 06:27 by Belamis)
Sudoku: Normal Sudoku rules apply.
Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
The shaded cells act as a German Whispers line: if two orthogonally connected cells are both shaded, then the digits in those cells must have a difference of at least 5.
Killer: Digits do not repeat in cages, and sum to the digit in the top left corner.
Cages include one shaded cell and one unshaded cell. In addition, a shaded cell within a cage indicates the number of shaded cells visible vertically and horizontally from that cell including itself, where unshaded cells block view.
Solution code: The shaded cells in column 6

I really enjoyed this, the logic is really clean and pleasant. Alas I screwed up initially by miscounting or something which I feel bad about because again, the logic was really nice and clear :D
Thank you again

Way easier and smoother than I originally thought given how small the clues are, very enjoyable though

Very impressive flow from such a minimalist starting point.
