## How to make a nonogram

1. Pick a difficulty. Choose a grid size from a gentle 5 by 5 up to a 15 by 15. Larger grids have more rows and columns to track, so the solve takes longer.
2. Generate the puzzle. Press Generate puzzle. You get a fresh grid with row and column number clues, and a hidden picture that the clues reveal. Every puzzle is proved to solve by logic, with no guessing.
3. Print the two pages. Press Print / save PDF. You get two pages: the empty grid with its clues on page one and the solved picture on page two.

## Publishing a whole book?

This tool makes one puzzle for home or the classroom. To make a nonogram book you can sell on Amazon KDP, Publisher Studio generates hundreds of graded picture-logic puzzles across a difficulty curve, at any KDP trim, as a print-ready interior and solutions PDF.

## Questions

**What is a nonogram?**

A nonogram, also called a picross or griddler, is a picture-logic puzzle. The numbers beside each row and column are the lengths of the filled runs in that line. You shade cells until every clue is satisfied, and a picture appears.

**Is this nonogram generator free?**

Yes. Pick a difficulty, generate a puzzle and print the grid plus its solved picture, with no sign-up and no watermark. It is free for classroom, home and personal use.

**Does every puzzle solve by logic alone?**

Yes. Every puzzle is generated so that row and column deductions alone reveal the whole picture, with no guessing, and that is verified by the same solver our Publisher Studio uses. A puzzle is never ambiguous or unsolvable.

**Does it include the answer?**

Yes. Every puzzle prints as two pages: the clues on page one and the solved picture on page two, so you can check your work.

**What size are the pages?**

The free tool prints at 8.25 by 11 inches, a popular large-print size. Our Publisher Studio will export the same book at any KDP trim, from 5.06 by 7.81 up to 8.27 by 11.69, as a print-ready 300 DPI interior.
