Welcome to Clue Boxes! I came up with this Sudoku series based on wooden puzzle boxes, where one small discovery leads to the next. Each puzzle works in a similar way: follow the clues, unlock the next step and see where they take you.
Rules:
Normal sudoku rules apply
Fog: All but one of the puzzle boxes are closed 'fog'. Fill in the correct numbers for the boxes to open.
Renban lines: Digits on the purple line form a set of consecutive digits in any order.
German Whisper lines: Adjacent digits on the green line must differ by at least 5. Digits on a line may repeat if allowed by other rules.
Greater than: The '>' symbol points to the lower of the two digits.
Enjoyed this one? See the other puzzles in the Clue Box series:
Clue Box #2: a Regional Sum Dutch Whisper puzzle.
Clue Box #3: a Zipper Killer puzzle.
Solution code: Column 5, top to bottom
