Large nonograms
A 15 by 15 nonogram is the largest size the free tool makes: thirty lines of clues and a picture with real detail. It is a long, satisfying logic solve for someone who has the smaller grids down, and like every puzzle here it is proved solvable without guessing.
Larger grids have more lines to track. Every puzzle solves by logic, with no guessing.
Customise colours
Clean drops the title band and footer, leaving the grid.
Two pages: the puzzle and its solved picture. Every puzzle is proved to solve by logic alone, by the same engine as our KDP studio.
