Slitherlink - PuzzleMonster

Slitherlink, also known as Loop the Loop or Fences, is a logic puzzle about drawing a single continuous loop along the grid edges. Each numbered cell tells you exactly how many of its four sides the loop must use. The loop never crosses itself and never branches, so every puzzle has one solution you can reach by pure deduction.

Features:
• Tap an edge to draw a line, tap again to mark it crossed out, once more to clear
• Numbers fade to grey once they have exactly the right lines around them
• A clue turns red if you draw too many lines around it
• Undo any move with a single tap
• Three difficulty levels: 7x7 Easy, 10x10 Medium, 12x12 Hard
• Progress saves automatically, so you can stop and pick up later
• Stats and best times for every difficulty
• Plays fully offline
• No third-party ads, only occasional suggestions for other PuzzleMonster games

A calm, addictive deduction puzzle that rewards patient thinking. If you like Sudoku, Hashi, or Nurikabe, Slitherlink could be your next obsession.
