Common questions

What you get, and how it works.

The questions the shop gets most often. If yours is not here, the address on the privacy page reaches a person.

Do I need an account or an email address?

Not for the samples. Every free file on this site is a direct download, with no form and no newsletter. The PDF books are sold through Etsy and the paperback through Amazon, and each store asks for whatever it asks for.

What do I actually get when I buy?

Five PDFs in one instant download: reMarkable 2, reMarkable Paper Pro, Kindle Scribe, US Letter and A4. The same puzzles are in every file, and only the page layout changes.

Why five files instead of one?

Because a page sized for one screen is the wrong size on another. Each file is drawn to its own device or sheet, so nothing is scaled down on arrival and the clue digits keep the weight they were given.

Can I print them?

Yes. The US Letter and A4 editions are laid out for home printing with the margins already set. Print at 100% rather than fit-to-page, and use the file that matches your paper.

Is there a printed book?

Only the complete collection. It is a 167-page paperback on Amazon, 8.5 by 11 inches, with all 150 puzzles and the answers at the back. The other books are sold as PDF downloads.

Is there an answer key?

Yes. The tablet editions give every puzzle its own full solution page, one tap from the grid and one tap back. The print editions collect the answers at the back so nothing is spoiled by a page turn.

What does one valid solution mean?

Every grid was checked by a solver before it went into a book, confirming that exactly one filling satisfies the clues and that deduction alone will reach it. You never have to guess, and a contradiction you find is real information rather than a flaw in the puzzle.

Which book should I start with?

The easy volume if nonograms are new to you, since its puzzles come out by reading single rows and columns. The complete collection if you already know you like them: it holds all three levels and costs less than the three books separately.

Is a nonogram the same thing as picross or hanjie?

Yes. Nonogram, picross, hanjie, griddler and paint by numbers are the same puzzle under different names, and these books work whichever one you learned it as.

Will they work on a device that is not listed?

Any PDF reader will open them. Pick the layout closest to your screen, or use a print edition on a larger tablet. Only the three e-ink layouts carry the two-way index links.

Can I use them in a classroom?

Yes, within the personal-use licence: print as many copies as you need for your own class or family. Reselling them or handing on the files is not covered.

Start somewhere.
