Play the puzzles for free, as much as you like, for personal enjoyment. No account is needed and nothing is charged.
The puzzle pictures and the written explanations on this site are original work. Please do not republish them in bulk or feed them into another puzzle catalogue. Linking to a page is always welcome.
The site is offered as it is. Puzzles are checked by an automated solver before publication, but if you find a grid that cannot be finished by logic alone, that is a defect worth reporting rather than a puzzle to be guessed at.
The site may change or disappear. Because your progress lives only in your browser, it is not backed up anywhere and cannot be restored.
This puzzle type goes by several names. This site calls it a nonogram and does not use the name Picross, which is another company's product name. Any names mentioned belong to their respective owners.
