Word search books are one of the most consistent sellers on Amazon KDP. They require no writing, no expertise, and can be created and published in a single day. This guide walks you through every step — from generating your first puzzle to uploading your finished book.
Creating a word search book for KDP requires very little. You need a free Amazon KDP account, a puzzle generator, and a way to export your puzzles as a PDF. You do not need design software, writing skills, or any paid subscriptions.
The tools you will use are all free. PuzzleForge handles puzzle generation and PDF export directly in your browser. Amazon KDP handles publishing, printing, and distribution at no upfront cost — they take a percentage of each sale.
The most important decision you will make is choosing your niche. A generic "word search book" competes with thousands of titles. A targeted niche — large print word search for seniors, Bible word search for kids, dog breed word search — faces far less competition and attracts buyers who search for exactly that.
Pick a niche you can build multiple books around. A series of 10 books in the same niche builds brand recognition and cross-sells naturally on Amazon.
Once you have your niche, create your word list. A typical word search book has 50 to 100 puzzles, each with 15 to 30 words. For a senior-focused book you will want larger grids and fewer, simpler words. For a kids' book, smaller grids with bright themes work best.
Use PuzzleForge to generate your puzzles. Select your page size, grid size, and word list. You can bulk generate up to 50 puzzles at once and export the entire set as a single PDF with answer keys at the back — exactly the format KDP expects.

Open PuzzleForge →KDP requires your interior file as a PDF. The most common sizes for puzzle books are 8.5x11 inches for standard activity books and 6x9 inches for digest-sized books. PuzzleForge exports at the exact size you select, so no additional formatting is needed.
| Page Size | Best For | Min Pages |
|---|---|---|
| 8.5 x 11 in | Large print, activity books | 24 |
| 6 x 9 in | Standard puzzle books | 24 |
| 5 x 8 in | Compact travel editions | 24 |
KDP requires a minimum of 24 pages for paperback books. A 50-puzzle book with answer keys will comfortably exceed this. Make sure your PDF has at least a title page, a brief introduction, all puzzles, and an answer key section.
Your cover is what sells the book on Amazon. KDP provides a free Cover Creator tool that is sufficient for getting started. Canva is a popular free alternative with more design flexibility. The key elements are a clear title, your niche keyword visible on the cover, and a clean professional design that matches your target audience.
KDP will give you exact cover dimensions based on your page count and size. Use these dimensions precisely — a cover that does not match will be rejected during upload.
Go to kdp.amazon.com and sign in. Click Create a New Title and select Paperback. Fill in your title, subtitle, author name, and description. Choose your categories — look for Puzzles & Games or Activity Books. Add relevant keywords in the keyword fields — this is how Amazon's search algorithm finds your book.
Upload your interior PDF and your cover file. KDP will run a print check and flag any issues with margins or resolution. Fix any flagged issues before publishing. Once approved, click Publish and your book will be live on Amazon within 72 hours.
Pricing depends on your page count and the royalty structure you choose. KDP offers 60% royalties for books priced between $2.99 and $9.99 through their expanded distribution. For a 100-page word search book, a price of $6.99 to $8.99 is competitive and profitable.
KDP will show you the minimum price based on printing costs before you finalize. Set your price above that minimum to earn a royalty on each sale.
Publishing one book is a starting point, not a strategy. The publishers who earn consistently on KDP build series — 5, 10, or 20 books in the same niche. Each book cross-promotes the others through Amazon's "Also bought" algorithm.
Optimize your book description with the same keywords your buyers search for. Update your books periodically to keep them fresh in Amazon's algorithm. Consider running Kindle Countdown Deals or Free Book Promotions to boost early visibility.
