Nonogram: Offline Logic Grids

Follow the numbers and uncover an abstract pattern in this offline nonogram game. Row and column clues describe groups of filled squares. Use fills and crosses to bring both directions into agreement. Explore 120 uniquely solvable pattern grids in 5 × 5, 7 × 7 and 9 × 9 sizes. Completed line clues fade to help you read the remaining work. These are logic patterns, rather than a gallery of named picture illustrations.

HOW TO PLAY
1. Numbers show the lengths of filled groups in each row and column, in order.
2. Leave at least one empty cell between groups. A zero means the whole line is empty.
3. Tap to cycle filled, crossed out and blank. Match every row and column clue.

WHEN YOU WANT A LITTLE HELP
Hints reveal one answer or safe cell. They are answer aids, not explanations of a logical deduction.
