Anti-Knight Uprising
(Published on 4. April 2024, 05:42 by Scruffamudda)
Normal sudoku rules apply.
The digit 9 is Anti-Queen and must not see itself by chess Queen's move.
A digit in an arrow cell shows the number of Anti-Knight cells seen in the direction of the arrow (not including the arrow cell). Once a digit has been identified as Anti-Knight all cells containing that digit are Anti-Knight cells. Anti-Knight digits must not see themselves by chess knight's move.
Solution code: column 9

At first I thought it was a bit chewy in the middle, nice start, but I very much disliked the middle part. reading the comments I knew it had to be me though.. so next day, fresh start and whaddya know, it's indeed a great puzzle start to finish ;-) Thank you

Happy, happy – that's my first solved 4 star sudoku.
Thank you very much for setting the puzzle, I enjoyed every second of solving it :-)

This is the first puzzle I dared to try to solve from Logic Masters (and I did it successfully)
I always watched cracking the critic but never dared to try a puzzle 100% on my own!
I encountered a deadly pattern at the end with some 5&8 in box 1 and 2 and since they were the last digits I needed I flipped a coin because I couldn't find what was I Missing, but otherwise I'm incredibly happy how I was able to solve it (even if it took me 2 hours and 6 minutes).

Really awesome puzzle! Note that the rule that 9 is anti-queen is missing here, took me a while to notice it on the SudokuPad page.
