About Slitherlink
Slitherlink is an elegant loop logic puzzle. Draw horizontal and vertical segments between dots to make one single, non-crossing closed loop. Each numbered cell must have exactly that many of its four sides used by the loop.
How to play
- Connect adjacent dots with edges to form one closed loop.
- A number says how many of that cell’s four edges are part of the loop.
- The loop never branches or crosses itself.
Tips & strategy
- A 0 means none of that cell’s edges are drawn — mark them off.
- Corners with 3s and adjacent 3s have forced edges.
