@thegriddle do you have any advice for first-time Area 51-ers? I don't have much experience with loop puzzles and this one seems rather large for a newbie like me. (are there good starter puzzles in your archive, perhaps?)
@sararielle Area 51 is a combination of Slitherlink, Masyu, and Cave/Corral, so brushing up on those could be a good place to start. https://thegriddle.net/15 is a good set of small and fairly-simple puzzles to start with. There are also plenty on https://puzz.link/db/ of varying difficulties.
