Nonogram
Play Nonogram puzzles, also called picross, online free in your browser. Numbers beside each row and above each column tell you the lengths of the filled blocks in that line. Use the clues across rows and columns together to work out which cells are filled, and a hidden picture appears. Every puzzle has exactly one solution, so it is pure logic, never guessing.
Play nonogram puzzles online free, the picture logic puzzle also known as picross, griddler or hanjie. The numbers along each row and column tell you the lengths of the filled runs, and you deduce which squares to fill until a small picture appears. There is no download and no sign-up, and you can start on a small five by five grid or move up to bigger boards as the row-versus-column technique clicks. Every puzzle has one solution, so it is solved by reasoning, never by guessing.

Tap a cell to fill it. Switch to Mark ✕ mode (or right-click on a desktop) to cross out cells you know are blank. The numbers count the lengths of the filled blocks in each row and column.
How to use it
- 1
Read the clues
Each number is the length of a run of filled cells in that row or column, in order, with at least one gap between runs.
- 2
Fill and mark
Tap a cell to fill it. Switch to mark mode, or right-click, to place an X on cells you have worked out must stay blank.
- 3
Reveal the picture
Cross-reference rows against columns to lock in each cell. When every filled block matches its clues, the picture is complete.
When it comes in handy
A logic puzzle with a payoff
Unlike a blank grid, a finished nonogram reveals a small picture, which makes the solve feel rewarding.
Pure deduction practice
Because every puzzle has one solution, progress always comes from reasoning, not from a lucky guess.
A scalable challenge
Start small at five by five and move up to larger grids as the technique of comparing rows and columns clicks.
Free, private & 100% in your browser

Frequently asked questions
- How do you solve a nonogram?
- The numbers on each row and column give the lengths of the filled runs in that line, in order. You work out which cells must be filled and which must be empty by comparing what each row clue allows against what each column clue allows. Filling a cell from a row clue often settles a column, which settles another row, and so on until the whole grid and its hidden picture are determined.
- What do the numbers mean?
- They are the lengths of the consecutive filled blocks in that line, listed in the order they appear, with at least one empty cell between blocks. A clue of 3 1 means a run of three filled cells, then a gap, then a single filled cell, somewhere along that line. A line with no filled cells shows a 0.
- Does every puzzle have one solution?
- Yes. Each puzzle is generated and then checked to confirm the clues force a single unique solution before you see it, so you never need to guess between two valid pictures. If you reach a point where you seem to be guessing, there is always a logical step you have not spotted yet.
- What is a good first step in a nonogram?
- Start with the biggest clue on each line, because long runs overlap themselves no matter where they sit. On a ten-wide row, a clue of 8 can only slide two cells either way, so the middle six cells are filled in every position and you can mark them right away. Do this for every row and column first, and those guaranteed cells give you footholds to work out the rest.
