Nonogram
Numbers along the edges spell out runs of filled cells — read them carefully, paint the grid, and a hidden picture appears.
How to play
A nonogram is a logic picture puzzle. The numbers beside each row and above each column list the lengths of consecutive filled blocks in that line, in order, with at least one gap between blocks. Use the clues from rows and columns together to deduce which cells are filled and which are empty.
There's exactly one solution and no guessing is needed. Fill every cell correctly and the grid resolves into a picture.
- Each clue number is the length of a run of filled cells in that line.
- Runs appear in the listed order with at least one empty cell between them.
- Mark cells you've ruled out so you can focus on the unknowns.
- A clue greys out once its line is fully satisfied; finish all lines to reveal the picture.
Controls
- Desktop: left-click fills a cell, right-click marks an ✕ (empty), and click-and-drag paints a whole line at once.
- Phone & tablet: tapping toggles single cells, but the drag-paint and right-click marking use mouse events — this puzzle plays best on a desktop or laptop with a mouse.
- Toggle 'Show mistakes' to highlight any cells filled in error.
Game modes
- Three sizes — 5×5, 10×10, and 15×15 — for a quick warm-up or a long solve.
- Daily — the same seeded picture for everyone each day.
- Practice — fresh random puzzles on demand.
Tips & strategy
- Start with the fullest lines: a clue whose runs plus gaps nearly fill the line forces overlapping cells you can fill immediately.
- Cross-reference — every cell you fill in a row gives new information to its column, and vice versa.
- Mark known-empty cells aggressively; ruling out space is as useful as filling it.
- Solve faster for a higher score — the timer steadily eats into your points.
