@DVFrank: You're welcome! Yeah, after the initial interactions the anti-knight logic is tricky but I'm glad it was rewarding to finish :-)

Wow, what an amazingly intricate construction! Took me an absolute eternity, but the finale was completely worth it! Hats off! :^)

Everytime I manage to solve one of your sudokus, I learn something. Another beautiful puzzle! :-)

Thanks tenaliraman for your kind words. I learn a lot too from both setting puzzles and solving puzzles by setters like yourself and many more on this wonderful portal. :-)

This is magic for me to be honest. Absolutely beautiful, crazy but beautiful. Took me an hour to realize that I put the 7's wrong and spent another hour and a half to do it again.
I'll never experience the moment I finally place the digits like this again, just too good. Just wonder how in the world can you even come up with such idea like this?

Wow, I never expected this to be so highly received. I'm really thrilled you had a magnificent experience! I have solved a few puzzles and set one with a similar kind of ending. Here is a list of a few puzzles that come to mind in rough order of difficulty:
clover's Anti-Knight Palindrome Thermo Sudoku (id=0004NY)
My (Partially) Anti-Knight Magical Queendom Sudoku (id=0003UA)
emmettcito's Irregular Miracle Sudoku (id=00043A)
AFrayedKnot's Anti-Knight Arrow Sudoku on CTC: https://www.youtube.com/watch?v=5D0byP3psnQ
In this puzzle, the symmetrical design helped ensure that there was a possibility of a late disambiguation. I failed in my first try, but when I looked at the finished grid, I then changed one of the arrows (in box 6) which did change the later logic.

Thank you very much! Very nice setting with such delicate interactions between arrows.

Took me 3 hours. Absolutely beautiful puzzle!
---
Thanks katsudon1cho for the persevering with it! Very well done in discovering the logic :-)

Wow! That was amazingly resistant to cracking. I actually placed all the digits except the 7’s in less than two minutes - but it took a lot of colouring and time to start placing them :-)
---
Thanks Godrick for the lovely feedback. In my first draft, the arrow sums cracked almost immediately. I'm really pleased you enjoyed the final version of the puzzle. :-)

Wow that was a mental workout! Beautiful interactions between the arrows, what a clever puzzle.
