Nonogram 10x10 is the classic size: ten rows and ten columns, up to five runs per line, and a picture you can finish on a coffee break. Every grid is checked so it solves without guessing. No app, no sign-up and no interstitial before play; it works offline and every cell can be filled or crossed from the keyboard.

Ten cells is long enough that few lines are fixed from the start, so overlap is the main tool.
Work out the slack: line length minus the clue's runs minus one gap between each pair. A single run of 7 has 3 cells of slack, so its cells beyond the first 3 from either end, cells 4 to 7, are filled. A clue of 3 4 needs 8 cells, leaving 2 slack: the 3 fills cell 3 and the 4 fills cells 7 and 8. Any run longer than the slack gives you cells.
A filled cell on the border belongs to the first run from that side, so fill its whole length and cross the cell after it. When a line shows all its runs, the clue dims; cross its remaining blanks so the crossing lines can use them.
After a pass over the rows, do the columns. On 10×10, two or three rounds usually open the grid. Use the five-cell guides to count without mistakes, and turn off Show mistakes as you play in Settings if you want to solve without help, then use Check at the end.
This page plays 10×10 grids up to 560 px wide, the same size the Nonogram hub starts on.
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. 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.
The 10×10 nonogram keeps cells at least 36 px on a phone and scrolls sideways when needed, with a Scroll toggle so a drag does not paint. 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.
Up to five runs per row or column. At most two rows and two columns are empty.
Often five to fifteen minutes, depending on practice. Your best and average times are saved in this browser.
Yes. Every grid is verified by a line-logic solver, so one line at a time is always enough.
With the default setting it is striped red and the Mistakes counter goes up. Clearing or crossing it removes the mark.
A one-finger drag paints by default. Turn on Scroll to move the board with a drag instead; a tap still marks a cell.
