Slitherlink is a pure logic puzzle where your goal is to draw one single closed loop on a grid of dots. Some cells contain numbers. Each number tells you how many of the four sides around that cell must be part of the loop. Use logic to place fences, mark impossible lines, and complete the board without guesses. The loop must be continuous, closed, and unbroken. It cannot branch, cross itself, or form multiple separate loops. Every solved level has exactly one loop.

A numbered cell must have exactly that many fences around it. For example, 0 means no fences, 1 means one fence, 2 means two fences, and 3 means three fences. You can also place red crosses to mark where fences cannot go. Red and green area markers can be used as notes to help separate regions and follow the logic of the loop. Start with simple clues, use marks to eliminate impossible moves, and avoid closing a small loop too early. The final answer must always be one single closed loop. Whether you want a quick relaxing level or a serious logic challenge, Slitherlink offers thousands of puzzles across multiple difficulty levels with no purchases required.
