How Nonogram Square works
A clue of 5 on a row 5 cells wide means every cell is filled. A clue of 2 and 2 means two blocks with at least one empty cell between them, as the tutorial explains. The CrazyGames description says every cell can be worked out by logic without guessing.
A first move to consider
Begin with the tutorial. It shows a row with the clue 5; drag across the row to fill all 5 cells, and it moves on to a row with two blocks. On a full puzzle, fill the longest clues first and mark cells you know are empty with an X.
The controls
CrazyGames lists the left mouse button to fill a cell or mark an X, with the pen button switching between them, plus Z to undo, Y to redo and the plus and minus keys to zoom. Dragging filled a whole row in our check. CrazyGames flags the game as working in iPhone and Android browsers; touch was not tested.
After a mistake
According to the CrazyGames listing, Z takes back the last change and Y puts it back. Our check did not confirm the undo, because the tutorial accepted the filled row at once.
Money and access
CrazyGames records no in-game purchases for this listing. The page links to a Google Play app, Nonogram Square: Picture Cross by GBong, which Google Play shows with ads and in-app purchases; that applies to the app. The browser tutorial showed neither.
Age and content
CrazyGames does not name a developer for this game. The linked Google Play app is rated 3+ there, a label for the app rather than this browser copy. The CrazyGames minimum age of 13 still applies to the site.
