Normal sudoku rules apply. Fog may be cleared by placing correct digits. All given lines in this puzzle are German whisper lines. Adjacent digits along a line have a difference of at least 5. Each line has its own color. Elements of the same color are connected. Additionally you have to build your own Between lines by matching clues (footprints to footprints, cookie crumbles to cookie crumbles etc). The clues act as the circled endpoints of a between line. All such lines must be connected by choosing the shortest possible orthogonally connected path that does not share any cells with any other line, including the German whisper lines. Digits along a Between line must be between the digits on the circled ends of the line. Digits in a cage do not repeat and sum to the value in the top left corner. Digits separated by a white dot are consecutive. On a black dot, one digit is double the other.
