onlinegamesbrowser.comHow to play
Beside every row and above every column sits a clue made of numbers. Each number stands for an unbroken run of filled cells, listed in the order they appear, and runs are always separated by one or more blank cells. So a clue of 2 4 means two filled, a gap, then four filled. Satisfy every clue and the filled squares form a picture. Each puzzle has one answer that logic reaches without guessing.
- Choose a grid from the Puzzle list: 20 numbered puzzles from 5×5 to 20×20, or a random one in any of those sizes.
- Fill a cell with a tap, or drag across a row or column to fill a stretch in one go.
- Mark squares you know must stay empty with a cross. On a phone, switch from Fill to Cross.
- A clue turns gray once its line matches it.
- Finish every line and the picture is done.
Controls
- Touch: tap or drag to fill, or flip the mode to Cross to mark cells that stay blank.
- Mouse: click or drag to fill, and right click to cross out.
- Keyboard: arrow keys move, Space fills, X crosses out, and Z undoes.
- Undo, Hint and Check sit under the board.
Tips
- Begin with the largest numbers. In a line of 10, a block of 8 has to cover the middle 6 squares no matter where it starts.
- Add the blocks plus one gap between each pair. If that total equals the line's length, the line is solved outright.
- A 0 clue means the entire line is blank: cross it all out straight away.
- Every cross you place is information for the crossing lines. Alternate between rows and columns as you go.
- Stuck? Hint first points out a wrong square if you have one, otherwise it reveals the next square that a single line can prove.
FAQ
What is a nonogram?
A logic puzzle that hides a picture. The numbers next to the rows and over the columns describe the runs of shaded cells in each line, and the finished grid forms an image. They are also known as hanjie or paint by numbers.
Will I ever need to guess?
No. Before a puzzle is shown, a solver makes sure the grid can be completed one line at a time by pure deduction, so there is exactly one answer.
Do the crosses count toward the answer?
No. Crosses are only reminders for you. The puzzle looks at the filled squares alone.
Can I play nonograms at school?
The nonogram game runs in an ordinary browser tab with nothing to install, so a school Chromebook can play it. Whether the page opens on a school network is the school's call, and if it is blocked there, only the IT team can change that.
