Rules: Draw a non-intersecting path through the centres of some cells. Circles mark the ends of the path, if given.The path is divided into sections of five cells, forming non-overlapping pentominoes. Consecutive pentominoes along the path must have different shapes, counting rotations and reflections as the same.The path must visit every clue and the clue indicates which pentomino it is part of.
