#120: Ring Pool
21 September 2023I made this one for a speed setting contest on the CtC Discord server. The prompt was to make a hybrid of any two genres, and the idea of combining Rail Pool and Ring-Ring had been on my todo list for a long time.
Sadly, the version I submitted to the contest was broken, because I overlooked a segment length. I’m quite happy with how this turned out, but I think this variant could use a bigger grid, because of how constrained it is.
Rules: Draw rectangular loops through the centres of empty cells so that every cell gets used. The sides of different loops may intersect each other, but not turn at their intersections or otherwise overlap each other.
Some boldly outlined regions contain number clues. If a side of a loop 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 side.
