About this game

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. 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.

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. To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.

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

Takes a minute to get used to knowing when it'll automatically put in an x instead of a line where you tap, but after that, it's pretty easy to play! I love the number of free puzzles they give you. They have options to help you if you get stuck or made a mistake. They have free weekly puzzles, and when you run out of freebies, you can buy more puzzles for very cheap! The company that makes this also makes some very good puzzle magazines. Let's keep supporting them!
