How do you play Slitherlink?

Draw a continuous loop along grid edges. Numbers indicate how many edges around that cell are part of the loop. The loop cannot cross itself and has no branches.

What do the numbers mean in Slitherlink?

Numbers 0-3 show how many of the four edges around a cell belong to the loop. Empty cells have no restrictions.

How is the loop validated?

The loop is valid when it forms a single closed loop with no crossings and no branches (each vertex has 0 or 2 edges).

Slitherlink is a logic puzzle where you draw a single continuous loop along grid edges. Numbers inside cells tell you how many edges of that cell are part of the loop.

How do you play Slitherlink?

Click on grid edges to toggle them as part of the loop. Each numbered cell must have exactly that many edges around it. The loop must be continuous with no crossings or branches.

What strategies help solve Slitherlink?

Start with 0 and 3 clues (they force all or no edges). Use X marks for edges you know are not part of the loop. Look for corners and edges where the loop is forced.
