Logic Masters Deutschland e.V.

Foggy Unique Constraints

• German Whispers: Adjacent digits along striped green lines must differ by at least 5
• Renban: Digits on thick purple lines must form an unbroken set of consecutive digits
• Region sum: Thin blue lines are divided into sections by the 3x3 region border lines, wherein each section must have the same sum (All region sum lines do cross at least one border)
• Black Kropki Dots: Digits with a black dot between them must be in a 1:2 ratio
• White Kropki Dots: Digits with a white dot between them must be consecutive
• V: Digits with a V between them must sum to 5
• X: Digits with an X between them must sum to 10
• Squares: Cells with squares must be even
• Each unique constraint type above must not contain any repeated digits anywhere within its specific constraint type (I.E. if a renban line has a 3 on it, no other renban line may contain a 3 in this puzzle)
• The grid is covered in dynamically cleared fog, placing a correct digit may clear fog elsewhere in the puzzle, no guessing is required
• Normal sudoku rules apply
