Kurotto Killer Sudoku
(Eingestellt am 29. Juli 2022, 04:21 Uhr von KNT)
Rules:
Normal sudoku rules apply.
Some cells in the grid must be shaded. A digit in a circle indicates the total count of shaded cells in orthogonally connected groups sharing an edge with that cell. Cells with circles cannot be shaded.
Every orthgonally connected group of shaded or unshaded cells forms a killer cage, i.e, a collection of cells in which no digit may repeat. A cell with a number in its top left corner indicates the sum of the digits in its orthogonally connected group.
Here is an example puzzle. It can be played here.

High 5 for me (in both senses)! I found this brutal, but I perservered for the intricate and clever logic.

Phew ! That one was quite challenging all the way through ! I was worried I might have broken it in the end because it seemed I had a shading disambiguation problem. And then the revelation came, and it was a perfect ending ! Thanks +++ again !!
