Dutch Flat Mates: Minimum Lines
(Eingestellt am 12. August 2026, 07:00 Uhr von Jobo)
Hello, enjoy this puzzle!
All feedback and comments will be much appreciated!
Happy to return as a guest setter for the Dutch Flat Mates series by Flinty, this time with Minimum lines!
Maximum lines should come along soon.. :)
Rules:
- Normal sudoku rules apply.
- Every 5 in the grid must have a '1' directly above it or a '9' directly below it. It may have both, but it doesn't need both.
- Digits on a lime green line can never be lower than the length of the line.

Lösungscode: Row 7.

Fun puzzle, but not that smooth for me. Maybe it was just my scanning, but I had some finding the needle in the haystack situations where I just happened not to look in the right places. I like the ruleset though, the max lines are quite elegant.
