About this game

Draw one loop. That's the whole rule... and it gets deep fast.

LineLoop is a modern take on Slitherlink (also known as Fences or Takegaki), the classic Japanese logic puzzle: connect the dots into a single closed loop so every number touches exactly that many edges. No guessing, no luck, no timer breathing down your neck — just clean, satisfying deduction.

WHAT'S INSIDE
• 450 handcrafted logic puzzles, every one verified to have exactly one solution
• Four difficulty tiers, from 2-minute warmups to expert grids that fight back
• Daily Loop — a fresh puzzle every day, with streaks to keep (and repair when life happens)
• Star ratings and 22 achievements to chase
• Smart hints that check your work when you're stuck
• A hands-on tutorial that teaches you in 60 seconds — no walls of text
• Clean, minimal design that gets out of your way, in light or dark mode
• No account, no clutter, small download

HOW TO PLAY
Tap between two dots to draw a line; tap again to erase it. Each number tells you exactly how many sides of that cell the loop passes through — a 3 wants three edges, a 0 wants none. Close the loop with no branches and no loose ends, and savor the moment it snaps shut.

The first levels teach you the logic; by the Hard tier, every clue counts. If you unwind with Sudoku, Nonogram picture cross, Picross, Kakuro, or loop puzzles like Zip, this relaxing-but-sneaky brain teaser is your next obsession.

FREE & PRO
The free version is fully playable, supported by ads. LineLoop Pro is a one-time purchase: no subscription, ever. It removes all ads, unlocks fully offline play (no wifi needed), and adds 3 free hints every day.

Made by a small studio that answers its reviews. Found a bug? Have an idea? Send feedback right from Settings. Every message still gets read.

Draw the line. Close the loop. Just one more puzzle.
