Normal sudoku rules apply. The grid is partially covered in fog. Correctly placing digits may clear fog somewhere in the puzzle. Correct digits do not necessarily clear fog from their own cells. Counting constraints: A digit on a constraint indicates the total number of times that digit appears on ANY of the constraints below. No cell contains more than one constraint. A) German whispers: Adjacent digits along a green line must have a difference of at least 5; B) Dutch whispers: Adjacent digits along an orange line must have a difference of at least 4; C) Nabner lines: No two digits on a yellow line may be the same or consecutive; D) Renban lines: Pink lines are filled with a consecutive set of non-repeating digits; E) Counting circles: A digit in a black-outlined counting circle indicates the number of times that digit appears in a counting circle; F) Odd circles: A digit in a gray circle must be odd; G) Kropki: Digits separated by a black dot have a ratio of 1:2 (i.e. one is double the other).
