Printable 15x15 Nonograms (Hard), Pack 2
Fifteen-by-fifteen nonograms are long, absorbing solves with clue lists up to the edge of the grid. Print one per sitting, keep a sharp pencil, and mark empty squares as you go.
Pack 2 of 5 has four nonograms with an answer key on the second page. Between 61 and 67 percent of the squares end up shaded, so no two grids look alike.

How to solve
- Read the clues: The numbers beside a row (or above a column) are the lengths of its shaded blocks, in order, with at least one empty square between blocks.
- Start with big blocks: A block longer than half the line always covers its middle squares, wherever it slides.
- Mark the empties: Put a dot or an X in squares that must stay empty. They cut lines into smaller pieces.
- Cross over: Every square you settle in a row is new information for its column, and the other way round.
