I miss ATK (Anti-Knight Palindrome)
(Published on 1. December 2025, 15:52 by galium_odoratum)
Normal Sudoku rules apply.
Shading: Cells containing values exactly one greater than an immediate neighbour (diagonally or orthogonally) within their box are shaded. All the shaded cells are given.
Anti-Knight: Cells a knight's move apart cannot contain the same digit.
Palindrome: Digits along a grey line must read the same forwards and backwards.
XV: Digits joined by a V sum to 5. Not all Vs are necessarily given.

uhm, maybe it's by design, but the palindrome is not needed to solve at all, not sure if the "V" is needed, frankly I doubt it...

Fun puzzle with Smooth solving once you get your head around the constraint :)

Completely forgot about this constraint. Nice to see it revived!
