How to Play
Slitherlink is played on a grid of dots. Numbers in some cells tell you how many of the four surrounding edges are part of the loop. Your task is to draw a single closed loop so every clue is satisfied.
The loop cannot cross or branch. A 0 means none of its edges are used; a 3 means three are used. Edges shared by two clues must satisfy both.
Controls
Click an edge to draw it, click again to mark it as excluded, and a third time to clear.
Scoring
Completion time and accuracy are scored. Slitherlink rewards recognizing local patterns.
