Nonogram

Fill in the squares that the numbers describe and uncover a hidden picture! Nonogram is a relaxing picture logic puzzle: the numbered clues of every row and column tell you which squares to fill. Pick a 5×5, 10×10 or 15×15 grid from a set of hand-drawn pictures or play endless random puzzles, mark empty squares with crosses, use hints and undo, and watch the clues grey out as you finish each line. Every puzzle can be solved by pure logic, no guessing!

How to play Nonogram

Each number tells you how many filled squares sit together in a row in that row or column; several numbers mean several groups, in that order, with at least one empty square between them. Choose Fill and tap or drag across squares to colour them, choose Cross to mark squares you know are empty, and Erase to clear them (a right mouse click crosses). On a keyboard use the arrow keys to move, Space to fill, X to cross, Backspace to erase, U to undo, H for a hint, Z to zoom and M to mute. When a row or column matches its clue, its numbers turn grey. Switch on the warning button to see wrong squares in red with a mistakes counter, or leave it off for a real challenge. On a small screen press the magnifier to zoom: the board scrolls while the clues stay in view, and a tap marks a square. Every puzzle has exactly one solution that you can reach by logic alone: start with the longest numbers and the nearly full lines. Finish the picture to see it revealed on the win card with your time and score; hints cost points. The puzzle list saves your progress for each size, including the puzzle you are working on, and random puzzles are new every time. Happy puzzling! 🧩
