Rules: Place some pentominoes and/or tetrominoes in the given grid without repetition. Figures may be rotated and reflected but may only touch each other diagonally. All the points of diagonal contact are given as black/white circles. Figures fall in two categories - one that touch circles of a single color, and one that touch circles of both colors. All pentominoes belong in one of the two categories, and all tetrominoes are in the other.
