This is a Saturday Crosslink puzzle.
When I first posted this variation, I suggested starting from scratch since this type is so different from standard Slitherlink. I’m going to retract that and recommend keeping in mind what you’ve learned from standard Slitherlink puzzles for this one. Just make sure to check very carefully that your logic still applies to these rules.
Also, it’s been pointed out to me that a rather unique element of a previous puzzle was very easy to miss without a clue. If you’re interested in finding out what it is, go back to puzzle 113 (it’s on the Author’s Favorites page). There is a hint below the solution if you can’t see what the trick is (it will be of limited help while solving though).
