Frequently asked questions

Is the Sudoku Book Maker free?: Yes. No account is required, the PDF carries no watermark and there is no limit on the number of books. Printing for personal, classroom or club use is permitted; resale is not. For commercial use, contact us.
How many puzzles can a book hold?: Up to 50, in any combination of the ten difficulty tiers. A 50-puzzle book is about 75 pages at one puzzle per page and about 45 at four per page, solutions included.
What paper size is used?: A4. Margins are equal on all sides and nothing prints within 17mm of an edge, so the layout is identical single-sided or double-sided. There is no bleed and no binding offset.
Are solutions included?: Yes. Every book ends with a solutions section, six grids to a page, and each puzzle lists the page number of its solution.
How is difficulty determined?: Each puzzle is solved by an engine limited to human techniques, with no guessing or backtracking, and receives a Peak Score from 1 to 100 based on the solve. The ten tiers are bands of that score.
Is the same book produced twice?: No. Each build draws a fresh selection from the library, so identical settings give different puzzles.
