Slitherlink (Pentominoes) (564)
Other names: Pento-slitherlink
Instruction:
Draw some loops that only consists of line segments between the dots along the dotted lines. Different loops may not share dots. A number inside a cell indicates how many of the edges of that cell are part of the loop.
Each loop must have the shape of a pentomino. No two loops may be shaped like the same pentomino; rotations and reflections are considered the same shape.
Notes:Variants:
- All twelve possible pentominoes should be found.
- Each number to the top or left of the grid reveals the number of cells in that row or column that are inside any loop(s).
