Tutorial for Nonograms / Griddlers / Picross

Nonograms (known across the globe under different names) are games based on a descriptive code - associated with every row and column of a table - which specifies the length of each group of consecutive blue squares on that line. This Nonograms tutorial helps you practice game-solving for a single row based on this descriptive code.

For each given code, mark accordingly the squares where you are certain about their value (blue or empty). Leave question-marks on the squares for which you don't have enough information to make a decision.

To begin, select a specific quiz type.
