The Great Black Spot

(Eingestellt am 9. September 2020, 23:22 Uhr von Geelow98)

  • 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.

Undoubtedly 1-star puzzle. Both for difficulty and quality.

You don't need to use the disjoint grouping rule to solve.
