About this game

A Nikoli logic puzzle where you draw a single continuous loop along grid edges

How to play

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).
