Friday Puzzle #13 - Digital Pent-By-Number
Rules: Paint some squares in the grid so that the shaded squares comprise the entire set of pentominoes indicated below the grid. Rotation and reflection of the pentominoes is allowed, but no two pentominoes can touch each other, even diagonally. The clues on the outside of the grid indicate the sum of the digits in connected painted squares in that row/column in order from left to right or top to bottom. At least one unshaded square must separate different sums.
