Knight Sweeper/ Springer Kehrmaschine
(Published on 30. April 2021, 16:13 by Ryx)
Normal Sudoku rules apply
Litte Killer - numbers along the indicated diagonal must sum to the number beside the arrow. Digits may repeat along the diagonal.
All non-circled cells obey the anti-knight rule.
For each number N from 2 to 7, the following is true: There are N circled cells that contain the number N. All circled cells that contain the number N must be connected through a chain of chess-knight moves. The chain may branch.
There are also 8 circled 8:s. Each circled 8 sees exactly one other circled 8 by a chess-knight move.

This puzzle was inspired by Phistomefel's "Chaos Construction: Minesweeper" puzzle (https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0005TN), that I recently saw solved by Simon on Cracking the Cryptic. Somehow I got it in my head "Knight sweeper", when hearing "Minesweeper" or I think at some point Simon said "Nine Sweeper".
And shout out to Goran H for improved rule description!

Fun knight's tour variant! Thanks, I really enjoyed it :-)
Ryx: You are very welcome. It was a real challenge to set, mainly because I approached it from the wrong end of the logic. Glad you enjoyed it!

This is a very good puzzle! Even though you were inspired by Phistomefel's puzzle, this is very much your own unique creation in a very different style. Very well done and very creative!
