Author/Opus: This is the 5th puzzle from guest contributor Freddie Hand.
Rules: Variation of Slitherlink rules. Draw a set of eleven pentomino-shaped loops (i.e., all but one of the given shapes) consisting of vertical and horizontal segments between the dots. Numbers inside a cell indicate how many of the edges of that cell are part of the loops. The pentomino-shaped loops cannot be in adjacent cells that share an edge or corner, and may be rotated or reflected.
