#032: Rail Pool — "Broken Sign"
6 September 2022Welcome! This is the first puzzle originally made for this blog. The earlier posts are all backdated, as I wanted to keep a record of some of the better puzzles I made over the last few months.
I’m surprised how few “extra regions” I had to add to make this unique. That 2x2 on the left is a little unfortunate, but I’ll take it.
Solve it online:
Rules: Draw a non-intersecting loop through the centres of all cells. Some boldly outlined regions contain number clues. If a straight loop segment visits any cells of a clued region, its length must match one of these numbers. Each number must correspond to at least one such loop segment. Question marks represent any positive integer, but numbers cannot repeat within a region.
