Free printable slitherlink

Slitherlink is a logic puzzle where you draw one closed loop along the dots so each number has exactly that many loop segments around it. Solvers who like careful deduction and clean, visual puzzles often enjoy working through each clue until the path closes cleanly.

This page offers a free, high-resolution printable puzzle image sized for a 6x9 inch page, plus a matching solution page. Both files are free PNG downloads with no signup required, ready to print at home or in the classroom.

How to play

  1. Scan the grid for numbers with only a few possible edges around them.
  2. Draw loop segments where a clue forces them, and mark edges that cannot be used.
  3. Connect segments into one continuous closed loop that never branches or crosses.
  4. Check every number has exactly the right count of neighboring loop segments.

Print the PNG at 100% scale (no fit-to-page) on letter or A4 paper with normal black ink so the 6x9 inch layout stays crisp and easy to solve.

Frequently asked questions

Where can I find the Slitherlink solution?

The matching answer key is included as a second image on this page. Download the solution PNG alongside the puzzle so you can check your loop when you finish, or keep it for later if you prefer to solve without peeks.

Is this free printable Slitherlink really free to use?

Yes. You can download both PNG files at no cost, with no signup required. They are free to print for personal use and classroom use. If you want to publish full puzzle books for Amazon KDP, SmartKDP also sells a complete puzzle book studio.

Who is this Slitherlink puzzle good for?

It suits anyone who enjoys logic puzzles that reward patient deduction. Beginners can start with clearer clues and build confidence, while experienced solvers will still appreciate the careful reasoning needed to close a single valid loop.

How should I print the puzzle and solution?

Download the free high-resolution PNGs and print them at 100% scale on letter or A4 paper so the 6x9 inch layout stays sharp. Use standard black ink for clean lines, and print the solution on a separate sheet if you want to keep the puzzle page unmarked.
