pH Anti-Knight Killer Sudoku
(Published on 18. July 2020, 16:49 by udukos)
Normal Sudoku rules apply.
Additionally, this puzzle is a killer sudoku with an anti-knight constraint.
Cells that are exactly a knight's move away from each other, may not contain the same digit. An area surrounded by a dashed line will be called a cage. Digits may not repeat within a cage. A number in the top left corner of a cage indicates the sum of all the digits in that cage.
Also, note the inequality sign in the grid.
The killer cage without the sum is not required for the solution. It's just their to maintain the symmetry.
Solution code: 7th column and 9th row

Edited the grid to increase the difficulty. The solution remains the same.
