Shade the False Killers
(Published on 12. January 2022, 18:30 by RockyRoer)
The Rules
- Normal sudoku rules apply.
- Numbers cannot repeat inside a killer cage.
- Numbers outside the grid, when given, indicate how many cells in that row or column must be shaded.
- Killer cages are either entirely shaded, or entirely unshaded. A killer cage total is shaded if and only if it is value is incorrect.

Are digits permitted to repeat in an unshaded cage or in a shaded cage?
Reply: numbers may not repeat in cages, regardless of shading.
