Nonogram - picture cross game

Nonogram is a logic puzzle game where you reveal hidden pictures by filling grid cells according to number clues. Simple rules, infinite depth — start as a beginner and progress toward mastery with thousands of challenges at your pace.

The game works like this: each row and column displays numbers that tell you how many consecutive filled squares appear in that line. A clue of "3 6 2" means three filled squares, then a gap, then six filled squares, then another gap, then two filled squares. Use this logic to deduce which cells to color and which to leave blank, and a hidden image emerges. Every puzzle has exactly one solution, verified by computer before it reaches you.

Over 100,000 puzzles span difficulty levels from beginner to Extreme, organized by grid size from 5×5 up to 50×50. Black-and-white and colored nonograms both appear in the collection, so you can switch between styles as your skills grow. New puzzles download automatically from the server whenever you need fresh challenges.

Play in two modes: freely fill any cell you like, or activate error limit mode to add tension and sharpen your focus. The app auto-detects mistakes so you can correct them instantly, and unlimited hints let you ask for guidance without penalty. Undo moves as many times as needed — there's no pressure to get it right the first attempt. An easy toolbar streamlines input for larger grids, and the game saves your progress automatically so you can resume exactly where you left off.

Score rankings track your performance, and daily challenges refresh each day for those who want competitive benchmarking. Auto-fill features complete obvious rows and columns once you've solved them, speeding up the endgame without removing satisfaction. Clean, beautiful graphics and optional sound effects create a calm, focused playing environment.

Nonogram sharpens logical thinking during commutes, before sleep, or anytime you want a mental workout that feels like play. The puzzle format forces you to think ahead, spot patterns, and avoid errors — classic brain training that doesn't feel like training. Whether you crave five-minute sessions or deep puzzle marathons, the game scales with your available time and mood.

The app runs smoothly on phones and tablets alike, with an interface scaled for both screen sizes. Every puzzle is free; no paywalls block access to the full collection. Nonogram - picture cross game delivers thousands of hours of logic puzzles in one tidy package.
