Nonogram
Follow the row and column clues to reveal a small picture. Twelve puzzles, two grid sizes, one solution each.
Numbers are runs of filled squares in order. Separate runs with at least one empty square. For example, 2 1 means two filled, a gap, then one filled. Right-click to mark a square empty, or use the × mode on a phone.

Frequently asked questions
How do I read a clue such as 2 1?
It means a run of two filled squares, at least one empty square, and then a run of one filled square, in that order. There can be empty squares before, after or between runs. A clue of 0 means the whole line is empty.
Do I have to mark every empty square with an ×?
No. The puzzle is complete when every required square is filled and no extra square is filled. Crosses are notes to help your reasoning. On a phone, switch to Mark empty; on a computer, right-click a square. Tapping a mark again removes it.
Do the pictures have more than one solution?
No. Each of the twelve pictures is checked by a solver that enumerates valid row patterns and tests them against the column clues. Only pictures with exactly one solution are included. The collection has six 5 by 5 starters and six 10 by 10 pictures.
What do Check and Hint do?
Check reports how many squares you have marked incorrectly without changing the board. Unmarked squares are not treated as mistakes. Hint fixes one square whose fill state differs from the solution and tells you its location. The hint counter remains visible, including if you undo that hint.
Why did a clue turn green even though the picture is unfinished?
Green means the filled runs in that line match its numbers. It does not independently prove their placement is right; the crossing lines still need to agree. Completion checks the entire picture, not just how many clues are green.
About this tool
Nonograms are picture logic puzzles. The hidden image is described by runs of filled squares rather than by colors or drawing instructions. Each row and column adds a constraint, and the picture emerges as you find the squares that both sets of clues require.
Begin with a line that is completely determined. On a five-square row, a clue of 5 fills the entire row, while 2 2 fills two squares, leaves the middle one empty and fills the final two. For a clue of 4, the three central squares must be filled no matter which end contains the gap. These overlaps are useful starting points.
After placing a run, check its crossing lines before adding more guesses. Marking empty squares makes completed runs easier to see and prevents accidentally joining two runs that should stay separate. On the larger boards, darker lines divide the picture into groups of five for easier counting.
The collection is finite and curated: twelve small pictures, each verified to have one solution. Check and Hint are optional, so you can choose how much help to use. Progress is kept only while this page stays open; reloading begins the first picture again.
