Too few puzzles and buyers feel short-changed. Too many and your printing cost eats your royalty. The right puzzle count depends on your format, your target audience, and how you are pricing the book. Here is what the data from top-selling KDP puzzle books shows.
| Puzzle Type | Minimum | Sweet Spot | Maximum |
|---|---|---|---|
| Word Search | 50 | 80–100 | 150 |
| Sudoku | 50 | 100–150 | 200 |
| Crossword | 25 | 50–75 | 100 |
| Word Scramble | 50 | 100 | 150 |
| Mazes | 50 | 75–100 | 150 |
The most consistently successful word search books on Amazon KDP have 100 puzzles. This number appears in titles — "100 Word Search Puzzles" — and buyers have been conditioned to expect it. It also fills enough pages at 6x9 to justify a $7.99 to $8.99 price point comfortably.
Books with fewer than 50 puzzles struggle to justify prices above $5.99, which significantly compresses the royalty. Books with more than 150 puzzles have high printing costs that eat into margins unless priced at $12.99 or above — a harder sell in most niches.
Sudoku buyers tend to be more dedicated puzzle solvers than word search buyers. They work through books faster and expect more value per purchase. The bestselling sudoku books on KDP frequently contain 200 or more puzzles across multiple difficulty levels.
A good structure for a sudoku book is 50 easy, 50 medium, and 50 hard puzzles — 150 total — with clear difficulty markers on each puzzle. This single volume serves beginners and experienced solvers without requiring a separate purchase.
Crossword buyers prioritize quality over volume. A book with 50 well-crafted crossword puzzles with accurate, engaging clues outperforms a book with 100 low-quality puzzles. The review quality on crossword books reflects this — buyers call out bad clues and incorrect answers explicitly.
For crosswords, aim for 50 to 75 puzzles and invest the extra time in clue quality. This pays off in better reviews, which drives more sales over time.
KDP requires a minimum of 24 pages for paperback books. Beyond the minimum, page count affects printing cost and royalty. Each additional page costs approximately $0.012 to print in black and white. A 200-page book costs about $2.40 more to print than a 100-page book — that comes directly out of your royalty or forces a higher price.
