This is a small, independent site for nonograms — picture logic puzzles, also known as Japanese crosswords or griddlers. It is not affiliated with any puzzle publisher.
Every puzzle here is checked before it is published. A solver walks the grid using only single-line reasoning — the kind a person actually does — and a picture is only published if that reasoning finishes the whole grid. When a grid finishes that way the answer is also the only possible one, so there is never a point where the sensible move is to guess and see.
The hint does not just open a square. It names the rule it used and lights up the line that rule was read from. The idea is that the hint teaches you the move rather than spending it for you.
What this site does not do: it has no accounts, no leaderboards, and no way to submit your own picture, because it is a set of static files with no server behind it. Your progress and your times stay in your own browser and are never sent anywhere.
All artwork here is original. If you believe a picture resembles something you hold rights to, please get in touch and it will be removed.
