Play nonogram puzzles in your browser, from a quick 5×5 to a long 20×20, plus a daily 15×15. Every grid is checked by a line-logic solver before you see it, so it can be finished without guessing. No app, no sign-up and nothing to dismiss before you play; it works offline and every cell can be filled or crossed from the keyboard.
Nonogram board is loading.
Every puzzle here can be solved one line at a time. You never need to hold two lines in your head at once: settle what you can in a row, and the crossing columns gain new information.
Push a run as far left as it can go, then as far right. Cells covered in both positions must be filled. In a line of 10, a run of 7 covers cells 4 to 7 wherever it sits. For a whole clue, add the runs and the single gaps between them: if a clue 4 3 in a line of 10 needs 8 cells, each run has only 2 cells of slack, so its cells beyond the first 2 are certain. A line whose clue plus gaps equals its length is fully determined.
Crosses are as useful as fills. When a line has all its runs, cross the rest. When a filled cell sits against the edge, the run it belongs to must start there, so you can fill its full length and cross the cell after it. Cells too far from any run are empty.
Each new fill or cross in a row is a new fact for a column. Go back and forth: rows, then columns, then rows again. Big clues are the best place to begin, and short clues in long lines usually wait until their crossings have narrowed them.
If you are stuck, the hint names one cell and why: Overlap, Forced fill, Line complete or Forced empty. Because every puzzle is line-solvable, a hint always exists unless there is a mistake, and then it points at the mistake first.
There are four sizes: 5×5, 10×10, 15×15 and 20×20. Between 55 and 65 percent of cells are filled. To keep clue margins tidy, a line has at most 3 runs on 5×5, 5 on 10×10, 7 on 15×15 and 8 on 20×20, and there is at most one empty row or column per five cells of size.
After a pattern is drawn, its clues go to a solver that looks at one line at a time and fixes a cell only when every placement of that line's runs agrees. The pattern is kept only if this settles every cell and matches the picture, which also proves the solution is unique.
Show mistakes as you play is on by default: a wrong fill is striped red and the Mistakes counter goes up. Turn it off to play without help and use Check when you want to see wrong fills.
Picture logic puzzles were created in Japan in the late 1980s, where printed grids of numbered clues turned into small black-and-white pictures when solved. Through the 1990s they spread to newspapers and puzzle magazines around the world under many names, among them griddlers, paint by numbers and picture cross puzzles. Nonogram is the common generic name today.
Printed nonograms are usually hand-made pictures. The puzzles here are random dot patterns instead, generated fresh and checked by a solver, so there is an endless supply and each one is guaranteed fair.
The hub plays 10×10. The daily is a 15×15 grid generated from the date, the same for everyone, with a new one at midnight UTC.
The timer starts on your first stroke and pauses when you switch tabs. Stats per size stay in this browser: played, won, win rate, best and average time, and your daily streak. Undo and Redo cover every stroke. The first two hints on a puzzle are free; if ads are switched on later, more hints offer a short ad or a 30-second wait. Wins come with share text, and random puzzles have a code such as A7K3Q that replays them.
Nonogram grids scroll inside their frame on a phone instead of shrinking, a Scroll toggle stops a drag from painting, and every cell can be filled or crossed from the keyboard. Tidy Puzzles runs entirely in your browser: there is no app to install, no account to create and no interstitial before you can play. After the first visit the game also works offline, because each puzzle is generated on your device from a seed. Every board can be played with the keyboard alone, on a phone or a desktop, and your stats and unfinished puzzles stay in this browser rather than on a server.
Use the number clues beside each row and above each column. They give the lengths of the filled runs in that line, in order, with at least one empty cell between runs. Fill cells that must be part of a run until the picture is complete.
Not here. Every puzzle is checked by a line-logic solver before you see it, so it can be finished one line at a time without guessing.
A cross is your own note that a cell is empty. It never counts as a mistake and is ignored when checking whether you have won.
Other names for the same puzzle. Nonograms have been published under many names since they spread from Japan in the 1990s.
Start with 5×5 to learn the idea, then move to 10×10. 15×15 and 20×20 take longer and reward working both directions.
They make random dot patterns rather than drawings of objects. That keeps the supply endless and every puzzle verified solvable.
Yes. Arrow keys move, Space or Enter fills, X crosses, Home, End, Page Up and Page Down jump to the edges, and H asks for a hint.
It points to one cell and gives the reason, such as Overlap or Line complete. If you have a wrong mark, it shows that first. Apply hint marks the cell for you.
