Clue Box #1

(Published on 11. July 2026, 12:20 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.

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.
