Colorlink is a variation of Slitherlink. The clues now appear in different colors. For every color that appears, a closed loop of that color must be drawn so that it satisfies the clues of the same color. A clue of one color has no bearing on a loop of a different color. Two loops of different colors may intersect or pass through each other, but they may not coincide anywhere. The solution is unique.
Below is an example puzzle and its only solution.
- There may be numbers of the standard black color. This does not signify the presence of a black loop, but instead tells how many total segments of any color surround that space. This means that there may be black 4s.
