The Great Black Spot

(Published on 9. September 2020, 23:22 by Geelow98)

Rules:
  • Cells separated by a knight's move or king's move (in chess) cannot contain the same digit.
  • Consecutive digits cannot lie in two cells connected orthogonally (i.e. sharing an edge).
  • Blacked out box in the middle is not neccessary to solve the puzzle.

The standard Sudoku rules apply.

Inspired by Richard's Sudoku Variants Series (190) - Blackout Sudoku.
