Normal Sudoku Rules apply but, instead of the usual 3x3 boxes, each irregularly-shaped 9 cell region must contain the digits 1 to 9. Digits in two orthogonally adjacent cells may not be consecutive. Cells separated by a knight’s move or a king’s move in chess cannot contain the same digit. In cages, digits must sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage.
