Nonograms

How to solve nonograms (griddlers)

Every row and column contains hints telling you how many filled cells belong together.

• Numbers next to a row or column define lengths of filled blocks.
• If there are multiple consecutive numbers of the same color, each block is separated by at least one empty cell.
• In multicolor nonograms, differently colored blocks can touch each other without an empty cell between them.
• At the start or end of a row/column, no empty-cell gap is required.
• Rows and columns must be correct at the same time.
• Mark confirmed empty cells to avoid filling them later.
• Start with rows or columns with large clues and use overlap logic.
