#74 - Rail Pool
The rail pools were some of my favorite puzzles in WPC, so I felt like writing another one for myself. I wasn't going to go for the empty middle initially but the original clue layout I chose made it almost resolve uniquely already, so I tweaked it a bit until it worked out.
Difficulty: 3/5
(rules from Puzzle Rules)
Draw a non-intersecting loop through the centers of all cells. Clues represent the different lengths of the straight line segments that are at least partially contained within the region. Each number within a region must be represented by at least one line segment.
