How to play Nonogram

Nonograms — also known as picture cross, picross, griddlers, or paint-by-numbers puzzles — are logic puzzles where the numbers reveal a hidden pixel picture. Play free nonogram puzzles online right here: choose a quick 5×5 grid to learn the ropes or a 10×10 grid for a proper brain teaser. The clue numbers outside the grid tell you the lengths of the runs of filled squares in that row or column, in order, with at least one empty square between runs. For example, a row clue of "3 1" means a block of three filled squares, then a gap of one or more, then a single filled square. Start with the biggest numbers: a 10 in a 10-wide row fills the whole line, and large clues overlap themselves no matter where they sit, so you can lock in their middle squares immediately. Use × marks on squares you know must stay empty — that is half the logic. Click or tap to fill a square, tap again to mark it with an ×, and drag to paint several squares at once; on desktop you can also right-click for × marks or solve entirely with the keyboard. The puzzle solves itself into a little picture the moment every filled square is correct — no guessing needed, every puzzle is hand-drawn pixel art. Stuck? The hint button fills one correct square for a 30-second time penalty. Beat your best time on 10×10 boards.
