Slitherlink
Easy — 5×500:00
ClassicAbout easy slitherlink
Easy slitherlink uses a 5×5 grid. About 70% of cells have number clues, and you will see plenty of 0s and 3s. A 0 lets you immediately exclude all four edges. A 3 in a corner forces two edges right away. Between these two patterns, large chunks of the loop fill themselves in.
Focus on the two core rules: numbef clues dictate how many edges belong to the loop, and every line segment must connect into one closed path. When you run out of obvious moves, check vertices. If a vertex already has two lines, its remaining edges are all excluded.
Once 5×5 takes you under 3 minutes, try medium.
