How to Create a Word Search Book to Sell on Amazon KDP
By WordGridly Editorial Team • Updated October 2026
Activity books and puzzle books represent one of the most profitable, evergreen niches in self-publishing on Amazon KDP. If you want to build a sustainable low-content book publishing business, this guide details the complete blueprint from niche research to interior PDF formatting.
1. Finding High-Demand, Low-Competition Niches
Generic puzzle books like "100 Word Searches" face immense competition. Instead, target passionate micro-audiences:
- Specific Hobbies: Gardening, woodworking, baking, knitting, birdwatching.
- Faith & Bible: Books of the Bible, women of faith, Christian hymns.
- Regional & Travel: National Parks of America, European capitals, Historic landmarks.
- Demographics: Large print word searches for seniors, easy puzzles for dementia patients, or travel games for teenagers.
2. Book Interior Architecture & Page Counts
Standard bestselling KDP puzzle books typically contain:
- Title & Copyright Page (Pages 1–2): Author name, copyright year, and pen name branding.
- 50 to 100 Puzzle Pages (Pages 3–102): 1 puzzle per page with large, readable grid and word bank.
- Solutions Section (Pages 103–128): 4-in-1 compact answer keys to save print costs.
3. Amazon KDP Printing Economics: Maximizing Margins
Amazon charges a fixed per-book print charge plus a per-page fee. By organizing solutions into a 4-in-1 grid, a 100-puzzle book requires only 125 total pages instead of 200 pages. This drops printing costs by over $0.80 per copy, dramatically increasing your net royalties on every sale.
