By Conceptis Ltd.

Slitherlink are addictive loop-forming puzzles which were invented in Japan. Using pure logic and requiring no math to solve, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

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.

The game features 2-finger tapping for quick zoom, auto complete clues setting and a link segment highlighting option to help to avoid creating separate loops.

For more fun, Conceptis Slitherlink includes a Weekly Bonus section providing an extra free puzzle each week.

It's a bit annoying that it's too easy to draw a line accidentally.

The error check and the techniques section is helping learn faster. So fun!

I enjoy the game a lot. I just wish there were also free larger puzzles available. The zoom option also could be improved.

Great but difficult logic puzzle (2.1)

They have different difficulty levels and lots of puzzles to do without paying. Controls could be easier (eg an eraser would be nice, and my finger often misclicks on the iPhone.)

Great fun (1.1)

I love different types of logic puzzles and this one is definitely staying on my phone. My only complaint is that I wish it had an eraser (clicking each individual line segment to delete is frustrating when I really messed up). I love all the Conceptis games!

Awesome! (2.0)

A wonderful slitherlink app. Would be nice to have some larger puzzles for the iPhone not just iPad - should be possible with the zoom in feature.
