- Anti-Knight restrictions apply, meaning identical digits may not be a knight's move away from eachother.
- Digits may not repeat on the diagonals.
- Normal killer sudoku-rules apply.
It's a (very) hard puzzle, but bifurcation is not needed. I do strongly advise keeping colouring pencils nearby...
Have fun!
Lösungscode: Row 6 followed by the diagonal from R9C1 to R1C9
