How to Create a 16 x 16 Sudoku Book for Amazon KDP

The 16 x 16 Sudoku wizard is available on every LogikLand plan, including the FREE plan, from the dashboard. Commercial rights, which you need to sell your books on Amazon KDP, come with the PRO and EXPERT plans.

The rules are those of the classic Sudoku, with boxes of 4 x 4 squares.

• The grid has 16 rows, 16 columns and 16 boxes of 4 x 4 squares.
• Every row, every column and every box must contain the numbers 1 to 16 once.
• Use the given numbers to work out the others. Every grid has a single solution.

These rules are printed at the start of your book when you add the “How to play” page.

1. 1

   Book settings

   Choose the language of your book (English, French, Spanish, German or Italian), enter its title, select the page size (8.5 x 11 inches or 6 x 9 inches), and decide whether to add a short “How to solve” page.

2. 2

   Puzzles

   Choose One level for a single difficulty, or Several levels to set a number of grids for each level in the same book.

3. 3

   Layout

   Choose the title of each puzzle (name, level and number, or the number only). Grids: 1 or 2 per page (1 in 6 x 9 inches). Hard level: 30 grids at most in a book. Solutions: 1, 2, 4 or 6 per page (1, 2 or 4 in the Large Print edition). Then set the top, bottom, left and right margins, from 0.25 to 2 inches. A page counter shows the estimated length of your book compared with the page limit of your plan.

   Generate, edit and export

   Click Generate Book. Your project opens in the visual editor, where you can change texts, fonts and positions, save your work, and download the book as a PDF or an editable PPTX file.

• Prefer the 8.5 x 11 inch format: the squares stay large enough to write two digits.
• Start with Easy grids: more than half of the numbers are given.
• Each generated book is checked for a single solution, so a Hard book takes a little longer to build.

Amazon KDP margin requirements depend on your trim size and your page count: the inside margin must be larger for thicker books. Check the official KDP margin guidelines, preview your file in the KDP previewer, and increase the margins in the Layout step if needed.
