It’s the first advent Sunday and we want to go for a walk. Nala doesn’t know where we planned to go yet so it’s a surprise for her and she loves to explore her surroundings! Normal sudoku rules apply. Digits in a cage must sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage. Help Nala find the path around the lake by following these rules: The path must be orthogonally connected and visit all cells of all cages. The path forms a loop (ie it has no start or end points). The path can touch itself diagonally, however it is not allowed to touch orthogonally (ie no cell on the path can share edges with more than two other cells on the path). Digits along the path differ by AT MOST 2. Cells separated by a white dot contain consecutive digits. Cells separated by a black dot contain digits in a 1:2 ratio (ie one digit is double the other). Not all possible dots are given. The grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
