The Phantom Locker

(Published on 18. March 2025, 04:16 by Sumanta(ANU))

This is a difficult version of the previous puzzle "Phantom Locker" I posted sometimes back. Try not to bifurcate and see if you can get the initial trick. Difficulty: 4 to 5, Enjoy:)

===Rules===

Anti-Knight Sudoku rules apply. (Cells connected by a single chess Knight move do not have repeated digits.)

Palindromes: The grey line is a Palindrome. (Digits read the same in both forward and backward directions).

Killer cage sum: The sum of the digits in a cage is given at the corner of the respective cages.

I have a question. Is the assumption for the killer cages that they CANNOT have repeats? I could test going down that route, but I don't really have the time to spend doing that if it's a fruitless search. Nice puzzle, otherwise!

Thanks,
Frank

@Hi Frank...Yes its an assumption that solvers know the killer cage sum rule :) :)...I shall try to be elaborative from the next time...Thanks for the solve and feedback.

Very nice! I noticed after 37 minutes that the puzzle was anti-knight, which could have saved me some time. Thank you
