Surround each clue with lines to form one single loop! Each puzzle consists of a rectangular lattice of dots with some clues in various places. The object is to connect the dots surrounding each clue so that the number of lines equals the value of the clue and the lines around all clues form one continuous loop with no crossings or branches. Empty squares may be surrounded by any number of lines. Slitherlink are addictive loop-forming puzzles which were invented in Japan.

Great app, needs dark mode
This app sorely needs dark mode, as the background is completely white. In the future, drag to draw would also be nice. I pay for a new pack every week, but it would be nice if there was a large one-time option or maybe a monthly subscription for full access. Definitely a five star app if it had dark mode.
Not perfect but fun
There are some boards with multiple solutions kind of ruining the fun, but they are good puzzles for the most part

A fun challenge
Good puzzles
Love the logic
This game has simple rules, but it can definitely pose a challenge to up your logic processing. I love the puzzles, and also love that they can be reset so you can play again at a later time. Highlighting the lines to see how close you are in forming a loop is very useful. And, for me, I also really like being able to check for errors during the game.
This version improves performance and stability.
