This post covers the most profitable and beginner-friendly types of puzzle and activity books you can create — even without any design background.
What Are Low-Content Puzzle Books?
Low-content puzzle books are books that primarily consist of repeatable game formats rather than traditional written content. They don’t require deep writing, but they do require thoughtful formatting and user-focused design.

- Educators, parents, travelers
Puzzle books are also a favorite among KDP authors because they:

- Require minimal writing
- Are suitable for bulk creation and series
- Can be evergreen or seasonal
- Perform well in print (especially 6x9” and 8.5x11” formats)
1. Sudoku Books
Sudoku is one of the most popular and trusted puzzle types in publishing. These number-based logic games are universally understood and highly addictive.
Why Sudoku Sells:
- Instant recognition — readers know what to expect
- Easy to produce in large batches

How to Create:
Use puzzle generation tools (like PuzzleGenerator.org) to export printable grids and solutions. You can create books with:
- 100 easy puzzles
- 3-in-1 difficulty books
- Daily Sudoku planners (1 puzzle per page)
- Large print versions for seniors
Add basic instructions, solutions, and a cover with clear difficulty level labeling.
2. Word Search Books
Word searches are engaging, educational, and perfect for kids and adults alike. They require minimal explanation and offer relaxing entertainment.
Popular Themes:
- Animals, countries, holidays, history

- ESL or language learning
- Inspirational and Christian themes
Tips:
- Use consistent grid sizes (e.g., 15x15)
- Group puzzles by theme
- Include an answer key section
- Use fun fonts and headers to increase perceived value
3. Crossword Puzzle Books
Crosswords require a bit more design effort, but they offer incredible value to the right audience. They appeal to older readers, hobbyists, and educated audiences.
Variations:
- Themed crosswords (e.g., Music, Sports, Cities)
- Easy crosswords for beginners
- Large print for older readers
- Classic American or British-style layouts
You can write your own clues or use automated crossword builders to streamline the process.
4. Cryptogram Books
Cryptograms are encoded phrases that challenge readers to decode messages. These books appeal to lovers of brain teasers and quote-based puzzles.
Formats to Try:
- Inspirational quotes
- Movie trivia
- Bible verses
- Famous speeches
Structure each puzzle on its own page, with a ciphered phrase and space for readers to decode. Always include a solution section at the back.
5. Maze Books
Mazes are visual puzzles that work well for both kids and adults. They can range from fun and simple to incredibly complex.
Creation Tips:
- Use maze generators with scalable difficulty
- Group puzzles by level (Easy → Hard)
- Add themed covers (e.g., “Animal Mazes for Kids”, “Challenge Maze for Adults”)
- Include a solution section with highlighted paths
Mazes are highly visual and benefit from clean, print-optimized design.
6. Word Scramble and Missing Vowels
These lightweight puzzles require players to unscramble letters or guess words with missing vowels.
Great for:
- Themed books (“Fruit Word Scrambles”, “US States Missing Vowels”)
- Vocabulary practice
- Language learners
- Holiday editions
Easy to generate in bulk, and pair well with images or illustrations.
7. Activity Book Hybrids
Many successful low-content books mix multiple puzzle types into a single themed activity book. This approach is ideal for kids or niche gift markets.
Examples:
-
“Farm Animals Activity Book for Preschool”
(Coloring pages, mazes, simple word searches) -
“Brain Games for Seniors”
(Large-print Sudoku, crosswords, word scrambles) -
“Holiday Activity Book for Kids Ages 6–8”
(Themed puzzles around Christmas, Easter, Halloween)
Pro Tip:
Organize your hybrid book into clear sections, label puzzle types, and include page numbers for answers.
Publishing Best Practices
Regardless of which format you choose, follow these KDP-ready tips:
- Use 8.5”x11” or 6”x9” trim sizes for puzzles
- Format pages with adequate margins (especially for printing)
- Include an answer section at the back
- Keep difficulty consistent and clearly labeled
- Design clean, readable covers that show the puzzle type
- Don’t forget your interior bleed settings if puzzles go edge-to-edge
If your audience is visually impaired or older, prioritize large-print formats and avoid overly decorative fonts.
