Nonogram (Picross) Puzzle Maker – Design & Play

A Nonogram, also known as Picross, Griddlers, or Hanjie, is a logic puzzle where you fill cells in a grid based on numeric clues. Each row and column has a sequence of numbers indicating the lengths of consecutive filled cell blocks. By combining row and column clues, you deduce the hidden pixel-art image.

Each number represents a contiguous block of filled cells. For example, "3 1" on a row means there is a block of 3 filled cells, followed by at least one empty cell, then a single filled cell. The order of numbers matches the order of blocks. A "0" means the entire row/column is empty.

In Design mode, click any cell to toggle it between filled and empty. The row and column hints update automatically in real-time. Create your pixel art, then switch to Play mode to solve it as a puzzle. You can also use the preset patterns or share your design via a link.

In Play mode, the filled cells are hidden. Use the Fill tool (left-click or press F) to mark cells you believe are filled, and the X Mark tool (press X) to mark cells you're certain are empty. Use the row/column hints to deduce the pattern. Click Check Solution to verify your progress.

Start with rows/columns that have large numbers (close to the grid size) or many blocks. Use the overlap method: if a block is long enough, some cells must be filled regardless of its position. Mark cells you know are empty with X to narrow down possibilities. Look for rows/columns that are nearly complete. Check for contradictions between rows and columns.

The tool supports 5×5, 8×8, 10×10, 12×12, and 15×15 grids. Smaller grids (5×5 and 8×8) are great for beginners and quick puzzles. Larger grids (12×12 and 15×15) offer more challenging and detailed pixel-art designs. The tool is fully responsive and works on mobile devices.
