[This is a repost from our archives with new notes at the top (original post here): This puzzle was perhaps easier than the Wednesday Slitherlink; by time standards it is about the same, but this grid is larger. However that was partially by design as this TIME puzzle would be on a weekend many readers of that magazine might click over to the site due to a world puzzle championship article. This is a puzzle that isn’t too hard if you try to intuit how the loop goes, but it is not using as many common patterns to get started.]
