Nonogram

• Shading
• Numbers
• Patterns

Reveal an image by deducing which cells must be filled from the clues.

1. Each clue lists, in order, the consecutive filled groups in a row or column.
2. At least one empty cell must separate two groups on the same line.
3. Choose size and difficulty independently. Fill, mark ×, drag, undo and ask for a logical hint.

• Add clue groups and their minimum gaps in a line; when little space remains, overlap reveals cells that must be filled.
• Start with lines whose groups and required gaps leave the fewest placements.
• Mark known empty cells with × to reduce the remaining possibilities.
• Five-cell separators help orientation on larger boards.

Nonograms, also known as Picross, popularized revealing pixel pictures through row and column number clues.

• Start with lines whose groups and required gaps leave the fewest placements.
• Mark known empty cells with × to reduce the remaining possibilities.
• Five-cell separators help orientation on larger boards.

• Where should I begin? Add clue groups and their minimum gaps in a line; when little space remains, overlap reveals cells that must be filled.
• What makes this game different? Choose size and difficulty independently. Fill, mark ×, drag, undo and ask for a logical hint.
