I miss ATK (Anti-Knight Palindrome)
(Published yesterday, 15:52 by galium_odoratum)
This is a tribute to Abdul the Killer, who (as far as I know) invented this lovely shading rule set. Since no one else seem to publish puzzles anymore using this shading rule set, I tried to create a puzzle on my own. If you are already familiar with this kind of rule set, I expect the difficulty to be 1.5* - 2.5*.
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.

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

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