Lupin's Loop 1 - No Shared Factors
(Eingestellt am 13. Mai 2026, 12:45 Uhr von Rab3aron)
Normal Sudoku rules apply.
Road: Draw a single road that travels orthogonally from cell to cell, never branching, crossing, or overlapping, and eventually closes into a loop. The road must pass through every house.
Traffic Lights: Borders marked with traffic lights are controlled intersections that the road cannot cross.
Segments: The bold 3×3 borders divide the road into segments.
No Shared Factors: Within each segment, all digits must be pairwise prime. That is, any two digits in the same segment share no common factor greater than 1.
Houses: A digit in a house equals the length of the segment containing it.
Speed Cameras: A digit in a speed camera counts how many road cells appear in the entire row of that camera, including the camera cell itself.
Note: A segment does not necessarily contain a house. Any segment of length 1 must contain the digit 1.
Lösungscode: Digits on the loop in column 6 from top to bottom.

Very beautiful construction!
I really enjoyed the logic behind finding the loop.
I’d say it’s around 3.5 stars for difficulty.
