Clue Box #2
(Published on 16. July 2026, 22:26 by Twan2797)
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.
Region sum lines: Box borders divide a line into segments that have the same sum (all segments in the same box count towards the same total). Digits on a line may not repeat. Region sum lines cannot branch or split.
Dutch Whisper lines: Adjacent digits on the orange line must differ by at least 4. Digits on a line may repeat if allowed by other rules.
Enjoyed this one? See the other puzzles in the Clue Box series:
Clue Box #1: a Renban German Whisper puzzle.
Clue Box #3: a Zipper Killer puzzle.
Solution code: Column 9, top to bottom

If you are having trouble like I was, please note that digits can't repeat on region sum lines. It is VERY slow going without that :)
