Free Printable Slitherlink Puzzles
Slitherlink, which some puzzle books call Loop the Loop or Fences, is drawn on a lattice of dots. Link neighboring dots into a single closed loop, with no crossing and no branch, so that each number shows how many sides of its square the loop uses: 0 for none, 3 for all but one.
Grids come in 5x5, 7x7 and 10x10 at Easy, Medium and Hard, with the 5x5 and 7x7 sizes also printed four to a sheet. Each grid hides exactly one loop.

About the slitherlink puzzles
How slitherlink works
Some squares between the dots hold a number from 0 to 3. Draw short lines from dot to dot until they close into one loop.
- One loop: a single closed path that never crosses or splits, so each dot has either two lines or none.
- Numbers: a number counts how many sides of its square are on the loop; an empty square sets no limit.
Slitherlink grid sizes: from 5x5 to 10x10
- 5x5: 36 dots, the size to learn the patterns.
- 7x7: 64 dots, room for a winding loop.
- 10x10: 121 dots, a loop that crosses the whole page.
Slitherlink difficulty levels
- Easy: plenty of numbers, solved by counting sides and applying the two-lines rule at each dot.
- Medium: fewer numbers, each read together with the dots at its corners.
- Hard: some sides call for a test, a line or a cross assumed until a rule breaks.
Slitherlink terms explained
- Side: the gap between two neighboring dots, part of the loop or not.
- Cross: a small x marking a side that cannot be part of the loop.
- Corner pattern: what a number in a corner forces, such as the two outer sides of a 3.
Printing the free slitherlink sheets
- Each size has a page with one grid per sheet, and 5x5 and 7x7 also have one with four framed grids per sheet.
- Sheets go from Easy, first, to Hard, last.
- Every sheet is available in PDF, SVG or WebP, sized for A4, and the whole page as a book PDF.
- The sheets show no loop; the Slitherlink generator makes new grids along with the loop that solves them.
