From the developer:
This program helps you solve existing SlitherLink puzzles as well as create new ones. Slither Link (also known as Fences and Loop the Loop) is a logic puzzle played on a rectangular lattice of dots. Some of the squares formed by the dots have numbers 0 to 3 inside them. The objective is to connect horizontally and vertically adjacent dots so that the lines form a single loop with no loose ends.
