Anti-Knight Killer Sudoku #3

(Published on 11. February 2021, 23:20 by Phistomefel)

This puzzle is a killer sudoku with an additional anti-knight constraint.

The usual sudoku rules apply. Additionally, cells that are a knight's move away from each other, may not contain the same digit. We call an area surrounded by a dashed line a cage. Digits may not repeat within a cage. A number in the top left corner of a cage indicates the sum of all digits in this cage.

As a small recommendation: I think it is helpful to write down the candidates for the cells only when there are few of them. With the large cages, it otherwise becomes very messy, as I found out. ;)

The puzzle is also available online via F-Puzzles. Have fun solving!

Solution code: First and last row

Just incredible! I loved how sometimes, one digit would affect the whole grid greatly.

Beautiful puzzle! A great example of how to use the anti-knight constraint well, without ever becoming a tedious scanning exhibit.
