Puzzle rules
Normal Sudoku Rules apply.
Cells a chess king's move apart must contain different digits.
In a cage, digits may not repeat and sum to the total in the top left corner (if given).
On a green German Whisper line adjacent digits differ by at least 5.
Digits separated by a white dot are consecutive.
If two digits are separated by a black dot, one is twice the other.
Not all dots are necessarily given.
