How to Create a Cross Math Book for Amazon KDP

The Cross Math 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.

Calculations are done in reading order, without priority for multiplication or division, and all the numbers are whole numbers.

• Each row and each column of the grid is a calculation, and its result comes after the equals sign. Write the missing numbers in the empty squares.
• Always calculate in reading order: from left to right in the rows, from top to bottom in the columns. There is no priority for multiplication or division: 2 + 3 × 4 = 20.
• All the numbers are whole numbers. There is always a calculation with only one number missing to start from, and 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, 2 or 4 per page (1 or 2 in 6 x 9 inches for Hard). 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.

4. 4

   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.

• Add the "How to play" page: it explains that calculations go in reading order.
• Easy grids use only additions and subtractions.
• Mix the levels in one book to make the difficulty rise from page to page.

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.
