Pentominos (Blokus) (117)

Other names: Blokus, Blokus (Pentominoes), Penta Touch, Pento-Blokus, Pentomino Touch, Touching Pentominos

Shade some cells so that the shaded cells form the shapes of twelve different pentominoes. Each pentomino shape is used exactly once, but can be rotated or reflected. Pentominoes cannot touch along edges, but can touch at corners. If a corner is marked with a dot, then two pentominoes touch at that corner. If a corner is not marked with a dot, then two pentominoes do not touch at that corner.
