Black & Solve: Nonogram

Black & Solve is a nonogram (picross) logic puzzle game. Use the number clues on each row and column to fill cells or mark them empty, and uncover the picture hidden in the grid. How to play Each clue lists the lengths of the black-cell groups on that line. Groups are separated by at least one empty cell. Fill what must be black, mark what must be empty, and work line by line until the grid is complete. No guessing is required when the clues are followed through.
