A nonogram (also known as picross, griddlers, hanjie, or Japanese crossword) is a logic puzzle where you fill in cells on a grid based on number clues. Each row and column has a set of numbers that tell you how many consecutive filled cells appear in that line. By combining clues from rows and columns, you can deduce which cells should be filled and which should remain empty.
Playing nonograms on free-nonogram.com is simple and instant. Choose your grid size — from a quick 5×5 puzzle to a challenging 20×20 brain teaser — select your preferred difficulty, and start solving. Click cells to fill them, or switch to cross mode to mark cells as empty. The clue numbers on each row and column guide your logic. When all filled cells match the hidden pattern, you win!
