Nonogram Square: Picture Cross

Solve logic puzzles with Nonogram Square: Picture Cross, a nonogram puzzle game featuring 4,000+ grids across multiple difficulty levels and game modes.

Nonograms—also called picross, picture cross, griddlers, hanjie, and paint by numbers—are picture logic puzzles where you decode number clues to fill cells and uncover hidden images. The rules are straightforward: numbers along each row and column reveal how many consecutive cells to fill. Use logic and deduction to complete the grid and reveal the picture. Whether you're a beginner or a puzzle expert, you'll find endless challenge and satisfaction.

Three game modes keep the experience fresh. Classic mode offers 100+ puzzles ranging from small grids perfect for learning up to large, complex layouts for seasoned players. Expert mode pushes your skills to the limit with the hardest nonograms available. Daily Challenge delivers one new puzzle every day—build your streak and maintain your habit of daily logic training.

Our signature Mosaic mode sets this game apart. Solve thousands of puzzles up to 25×25 that combine into stunning large images, like assembling a jigsaw puzzle piece by piece. Available in both Classic and Expert difficulties, Mosaic transforms puzzle-solving into an epic creative journey.

Every puzzle is completely free—all 4,000+ grids are unlocked with no paywall restrictions. Intuitive touch controls let you tap and drag to fill cells, with pinch-to-zoom for detailed work on large grids. Made a mistake? Undo and redo as many steps as needed. Your progress auto-saves, so you can pause anytime and pick up exactly where you left off. Google Cloud Save syncs your game across all your devices, letting you switch between phone and tablet seamlessly.

Play offline—no internet required—making Nonogram Square perfect for commutes, travel, or any moment you want to unwind. Dark mode eases eye strain during late-night solving sessions. When you're stuck, the hint system gets you back on track without spoiling the solution.
