A Nonogram (also called Picross, Griddler, or Hanjie) is a logic puzzle where you fill a grid based on number clues for each row and column. Every valid Nonogram has a unique solution derivable through pure logic.

What cognitive skills do Nonograms build?

Nonograms develop logical deduction, constraint-satisfaction thinking, working memory, and systematic problem-solving. They are a form of pure logic puzzle requiring no domain knowledge.

Do Nonograms require guessing?

No. A well-formed Nonogram is always solvable through logical deduction alone. If you feel stuck, a new constraint will become apparent from a different row or column.

Is MindPlay Nonogram free?

Yes, completely free with no account required.
