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.
