Slitherlink Puzzles by KrazyDad

Slitherlink is an addictive logic puzzle that was first published by Nikoli in Japan. The puzzle consists of a grid of dots, with some clue cells containing numbers. You connect horizontally or vertically adjacent dots to form a meandering path that forms a single loop or "Slitherlink." The loop must not have any branches and must not cross itself. The clue numbers indicate how many lines surround the cell. Empty cells may be surrounded by any number of lines (from 0 to 3).

There is one unique solution, and you should be able to find it without guessing. You may find it helpful to make Xs between dots that cannot be connected.

Here are hundreds of free Slitherlink puzzles suitable for printing.
