Nonogram — logical deduction & patterns

💡Benefits

Nonogram (a Japanese crossword) is a pure logic puzzle: from the number clues the child deduces which cells must be filled AND which must stay empty. It strengthens deductive reasoning, working memory and spatial perception (Diamond, 2013). It builds the habit of acting on proof rather than guessing.

🎮How to play

Next to each row (left) and column (top) there are numbers — these are groups of consecutive filled cells. For example “3 1” means: first 3 cells, then at least one gap, then 1 cell. In Fill mode tap cells to fill them, and in Mark mode place an ✕ on cells you believe are empty. The puzzle is solved when the filled cells exactly match the hidden picture. 3 levels: 5×5, 10×10, 15×15.
