About 40×40 Nonograms
A 40×40 Nonogram is a long focus session: more cells mean denser clue lists and fewer trivial full-line fills. Work methodically — clear forced fills, mark safe empties, then revisit lines.
Use Undo/Redo freely, keep Auto on for completed lines, and treat Hint as optional (unranked). The board scrolls when needed so cells stay readable.
