Frequently Asked Questions
Which book should I start with?
If the cube is new to you, start with Volume 1: the 4×4 and 6×6 cubes show how the faces connect before the 9×9 puzzles. If you already solve classic Sudoku, try Volume 2 or 3. The 365 book takes you from easy to extra hard over a whole year.
Which language is the book in?
Each purchase includes the PDF in all 14 languages; you choose the language when downloading.
How do I get the PDF after paying?
The PDF is ready on the confirmation page right after payment, and a download link is also sent to your e-mail. A link works for 30 days and 10 downloads per book; for three years you can request a new one with the same address.
Can I print PDF books on a standard home printer and how do QR codes work?
Yes. All PDF books are vector files in Letter size (8.5 × 11″) with generous margins, and they also print well on A4 when scaled to fit the page. Large 5.5 mm cells give plenty of room for pencil notes. Every puzzle includes an interactive QR code you can scan with your smartphone to instantly check your work or continue solving in 3D on play.cubesudoku.com.
Can I return a PDF?
Before paying, you ask for immediate delivery and confirm that you lose the right of withdrawal once the download starts. If a file is faulty or does not match its description, write to [email protected] and we will fix it or refund you.
