About this puzzle book

800 sudoku puzzles in four levels as a hyperlinked PDF for BOOX, with a tappable difficulty page, a checklist for each level and every answer at the back.

The Sudoku Puzzle Book for BOOX is a hyperlinked PDF with 800 sudoku puzzles, 200 at each of four levels: Easy, Medium, Hard and Very Hard. Each puzzle gets its own page with the grid drawn across the full width of the screen, so there’s room to write a digit in every square and still fit small pencil marks in the corners.

We checked every puzzle with a solver before shipping the file, and each one has exactly one solution. The answers sit at the back of the book, grouped by level.

What is inside

800 puzzles, one per page, numbered 1 to 800.
Four levels of 200 puzzles each. Easy puzzles start with 62 numbers filled in, Medium with 53, Hard with 44 and Very Hard with 35.
A Choose difficulty page with one tappable box per level.
A list for each level with every puzzle as a tappable row and a tick box to mark the ones you’ve finished.
A How to play page with the rules and a short solving method.
Answers for all 800 puzzles, six solved grids per page.

How the levels work

The levels are set by how many of the 81 squares are filled in when you start. Easy leaves 19 to solve, which makes a good warm-up. Very Hard starts with 35, so most of the grid is yours to work out and you’ll lean on pencil marks a lot more. The puzzles are numbered straight through the book: Easy is 1 to 200, Medium 201 to 400, Hard 401 to 600 and Very Hard 601 to 800.

How navigation works

Everything runs in your BOOX’s built-in PDF reader, with no extra app to install. The cover opens on a contents page, and every list, puzzle and answer page has a breadcrumb at the top that takes you back a level in one tap, plus arrows to the previous and next page. Each puzzle page has a small Answer link in the corner that opens the page with its solution, and the number on each answer links back to its puzzle. The links are standard PDF links, so tapping them works in the reader.

The PDF also carries bookmarks for the cover, the contents page, each section and the answers, for any reader that shows a PDF’s outline.

Getting it onto your BOOX

After checkout you get one download for the BOOX you picked. Grab it on a computer or phone first so you have a copy you can find again.

Then send it from your computer with BOOX’s BooxDrop transfer and open it in the built-in reader. Write on any page with the stylus.

It’s a digital download. There’s nothing to print or ship, and the PDF is yours to keep and download again.

Frequently asked questions

Which level should I start with?

If you’re new to sudoku, start on Easy: each puzzle has 62 of the 81 squares filled in, so there are only 19 to work out. If you already solve newspaper sudoku, Hard (44 given) or Very Hard (35 given) will feel closer to what you’re used to.

Will I see the answer to the next puzzle by accident?

The answers are at the back of the book, grouped by level and six to a page, so you only see them when you go looking. The Answer link on each puzzle page takes you to the page that holds its solution.

Can I erase my answers?

Yes. Your writing sits on top of the PDF page, so the eraser removes your digits, lines and pencil marks and leaves the printed puzzle as it was.

How do I get the file?

After checkout you can download it from your order confirmation page, your order email or the Downloads tab in My Account.

Which BOOX models does this fit?

The BOOX Tab Mini C (7.8″), Note Mini C (8.5″), Note Air 10.3″ and Tab Ultra 13.3″. Each size gets its own file drawn for its screen, so choose yours at checkout. Other BOOX models need a different file.

Can I print it?

It’s laid out for the tablet screen, not for paper. You can print pages for your own use, but they come out at the tablet’s page size rather than a full sheet.
