To make a good sudoku puzzle book, you need to make sure that you puzzles are large enough to view for most people, have a good-sized gutter in the margin, and have the right level of difficulty for your audience.

Coloring Books

Kids love coloring books. These are popular all year round to keep kids busy, but they sell exceptionally well during Christmas. The following tool beats out the other options because it not only removes the color from images, but it also has an adjustable slider that allows you manipulate the final image to make it as clear as possible for your book.

I love doing crosswords and there are loads of people that still enjoy them. Making a good crossword book is more difficult than most other puzzles. This also means that there are fewer people are selling them online, so there’s much less competition.

My favorite free crossword puzzle generator is CrosswordLabs.

Color By Number

This is another difficult puzzle type to make. There will be a lot of trial and error before you get the final image done correctly, but once you’re done – you’ll have a product that most people are unable to create.

And now for the puzzle generator that I use to make a full-time income selling KDP puzzle books. Unlike the other puzzle generators I’ve used in the past, this tool gives me complete control of how the final product looks. Instead of having a website making the puzzle and being stuck with a final product that I don’t like – I can now edit everything, the position of the puzzles, fonts, sizes, number of puzzles per page, pretty much everything. The software creator even has a Facebook page that you can contact him on to request changes/additions to the software. The best part is that it’s an add-on for Powerpoint. If you’ve used PowerPoint before, you’ll know that it is the perfect tool for designing puzzles, and they can be easily converted into PDFs directly in PowerPoint.

There are constant updates and puzzles being added, but the current list of puzzles included consists of – sudoku, word search, crosswords, coloring pages, calcudoku, tic tac toe, nurikabe, kakurasu, number place, ABC path, hangman, missing vowels, word scramble, skyscraper, mazes, cryptograms, word puzzles, mine finder and warships.

This is the best puzzle generator I’ve ever come across.
