Slitherlink: Fences and Loop

One Loop One Solution

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Draw one perfect loop using logic. Infinite puzzles, offline play, light/dark mode, and 100 challenge levels included. Slitherlink is a classic logic puzzle played on a grid. Some cells contain number clues. Your goal is to draw a single continuous loop along the grid edges so that every clue is satisfied. Each number tells you how many of its four sides must be part of the loop. The loop cannot branch, cross itself, or form multiple smaller loops. Every puzzle has exactly one correct solution and can be solved using logic and deduction alone — no guessing required. Simply tap the space between two dots to switch edge states: line → X → empty. Mark lines to build your loop and use X to eliminate impossible edges. Enjoy unlimited fun with infinity puzzle generation, so you will never run out of challenges. Play offline anytime, anywhere. Choose Quick Mode with Easy, Medium, or Hard difficulty, or test your skills in Challenge Mode with 100 handcrafted levels. The game supports both light and dark mode for comfortable play day or night. Clean design. Pure logic. Endless puzzles.
