Crossword puzzle books are the premium tier of puzzle publishing. While they're harder to create than Sudoku or word search, quality crosswords command higher prices ($9-$14), attract loyal repeat buyers, and face less competition from amateur publishers who can't meet the quality threshold.
🎯 Crossword Book Market Reality Check
- Market size: "Crossword puzzle books" gets 60,000+ monthly Amazon searches
- Competition: Very High (dominated by established publishers like Simon & Schuster, USA Today)
- Quality barrier: 80% of indie crosswords fail due to poor clue quality
- Price premium: Well-made crosswords sell for $9.99-$14.99 vs $6.99 for word search
- Repeat buyers: Crossword enthusiasts buy 10-20 books annually (highest in puzzle category)
- Production time: 3-5x longer than other puzzle types (worth it for premium margins)
Why Crosswords Are Different (And Harder)
The Quality Challenge
What makes crosswords difficult to automate:
- Clue quality: Automated clues are often awkward or ambiguous (biggest complaint in reviews)
- Theme integration: Professional crosswords have clever themes connecting answers
- Grid symmetry: Traditional crosswords follow strict symmetry rules
- Fill quality: Avoid obscure words and excessive 3-letter answers
- Difficulty calibration: Consistent difficulty requires human curation
The Reality: You Need Help
Unlike Sudoku or word search, you can't just generate 100 crosswords and publish. You need either: (1) premium software with quality databases, (2) manual curation/editing, (3) hiring puzzle constructors, or (4) focusing on niche formats where lower standards are acceptable.
Crossword Types & Difficulty Levels
| Type | Grid Size | Difficulty | Best Market |
|---|---|---|---|
| Easy/Beginner | 13x13 | Simple clues, common words | Seniors, beginners |
| Standard/Medium | 15x15 | Moderate vocabulary | General audience |
| Challenging | 17x17 or 19x19 | Cryptic clues, wordplay | Enthusiasts |
| Sunday Size | 21x21 | Varies (more answers) | Premium books |
| Quick/Mini | 7x7 or 9x9 | Fast solves (5-10 min) | Commuters, casual |
Crossword Generation Options
Option 1: Professional Software (Best Quality)
Crossword Compiler ($69-$299)
- Pros: Industry-standard tool used by NYT constructors, extensive word lists, quality clue databases
- Cons: Steep learning curve (1-2 weeks), manual refinement still needed
- Best for: Serious publishers planning 10+ books
- Output: Professional-quality grids, but clues require editing
EclipseCrossword (Free, Windows)
- Pros: Free, simple interface, good for basic crosswords
- Cons: Limited word lists, no theme support, basic clue suggestions
- Best for: Testing concepts, small projects (not recommended for commercial books)
Option 2: Hire Professional Constructors
Where to find constructors:
- Upwork/Fiverr: $20-$50 per quality crossword (15x15)
- Crossword Discord communities: Amateur constructors seeking portfolio work
- Puzzle Baron Forum: Experienced constructors available for commission
Cost analysis: A 100-puzzle book at $30/puzzle = $3,000 upfront investment. If book earns $3.50 royalty per sale, you need 857 sales to break even. Realistic with good marketing over 12-18 months.
Option 3: Curate Public Domain Crosswords
Sources for vintage crosswords (70+ years old, public domain):
- Archive.org newspaper collections (1920s-1940s crosswords)
- Old puzzle magazines from Project Gutenberg
- Recreate classic grids with modern clues
Modernization required: Vintage crosswords need updated clues (references to rotary phones, telegrams, etc. won't work). Expect 10-15 min per crossword to modernize clues.
Option 4: Niche Formats with Lower Standards
Formats where automation works better:
- Fill-in crosswords: Word bank provided (easier, lower standards accepted)
- Themed word lists: "Bible Crosswords" (limited vocabulary, specific clues)
- Educational crosswords: "Spanish Vocabulary Crosswords" (teaching tool, not entertainment)
- Large print simple crosswords: 9x9 grids for seniors (simpler vocabulary expectations)

Get Started FreeQuality Control: The Make-or-Break Factor
Essential Quality Checks
1. Clue clarity test:
- Read each clue - does it have ONE clear answer?
- Ambiguous example: "Bank" (could be riverbank or financial institution)
- Better: "Financial institution" = BANK
2. Vocabulary appropriateness:
- Easy books: 95% common words, 5% moderately challenging
- Medium books: 85% common, 15% challenging
- Hard books: 70% common, 30% challenging, no obscure words
3. Grid quality:
- Avoid excessive 3-letter words (max 20% of answers)
- Verify rotational symmetry (180-degree grid pattern)
- No unchecked squares (every letter crosses with two words)
- Balanced distribution of across/down clues
4. Solve every puzzle yourself or hire beta testers:
- Unsolvable puzzles = instant 1-star reviews and returns
- Hire 2-3 beta solvers on Fiverr ($5 per puzzle review)
- Total QC cost: $500-$1,500 for 100-puzzle book (worth it)
Common Automated Crossword Failures
❌ Red Flags in Generated Crosswords
- Circular clues: "Large cat" for LION and "Lion-like" for CAT (unhelpful)
- Dictionary definitions: "A large bovine animal" instead of "Farm milk producer"
- Obscure words: ESNE (Anglo-Saxon slave) - no one knows this
- Abbreviation overload: Too many abbrev. clues in one puzzle
- Cultural insensitivity: Outdated or offensive terms (run spell check + sensitivity review)
Book Structure & Formatting
Optimal Specifications
Trim size: 8.5" x 11" (standard), 7" x 10" (portable), 6" x 9" (travel)
Page count: 120-200 pages (50-100 puzzles depending on size/difficulty)
Paper: White interior (cream is harder to read grids)
Interior Layout Best Practices
- Grid size: 6" x 6" minimum for 15x15 puzzles (comfortable solving)
- Font: 9-11pt for clues, 12-14pt for grid numbers
- Clue formatting: Two-column layout (Across | Down) or single column
- One puzzle per spread: Grid on right page, clues on left (avoid flipping)
- Puzzle numbers: "Puzzle 23" clearly marked for solution reference
Front Matter Essentials
Page 1: Title page
Page 2: Instructions
- How to solve crosswords (for beginners)
- Difficulty level explanation
- Tips for solving (start with easiest clues, work outward)
Page 3: Sample puzzle with solution (builds confidence)
Solutions Section
Format options:
- Full-size grids: One solution per page (most user-friendly, higher page count)
- Compact format: 4 solutions per page in smaller grids (cost savings)
- Answer key only: List of answers without grids (compact but less helpful)
Pricing Strategy
| Book Type | Puzzle Count | Price Range | Royalty |
|---|---|---|---|
| Easy/Beginner | 80-100 | $7.99-$9.99 | $2.80-$3.60 |
| Standard/Medium | 60-80 | $9.99-$11.99 | $3.60-$4.40 |
| Challenging | 50-70 | $10.99-$13.99 | $4.00-$5.20 |
| Large Print (Seniors) | 50-80 | $9.99-$12.99 | $3.60-$4.80 |
| Themed/Specialty | 60-80 | $10.99-$14.99 | $4.00-$5.60 |
Price justification: Crosswords justify 20-30% higher prices than word search due to perceived quality and longer solve times. Don't compete on price - compete on quality.

Should You Create Crosswords?
Create Crosswords If:
- You have $3,000+ budget to hire professional constructors
- You're willing to invest in Crossword Compiler ($299) and learn it thoroughly
- You can manually curate and edit generated puzzles (5-10 min per puzzle)
- You're targeting premium markets (seniors, enthusiasts) who pay $10-$15/book
- You have experience with easier puzzle types and want to level up
Start with Easier Types If:
- Limited budget ($0-$500)
- Want faster time-to-market (crosswords take 3-5x longer)
- Prefer automated generation with minimal editing
- Testing KDP waters before major investment
- Prioritize volume (10 word search books vs. 2 crossword books in same time)
Alternative Strategy: Fill-In Crosswords
What are fill-in crosswords?
Also called "Criss-Cross" or "Word Fit" puzzles. Solvers place words from a provided list into the grid. No clues needed = much easier to create.
Fill-In Advantages
- No clue writing: Biggest time saver
- Easier QC: Just verify word list matches grid
- Lower skill barrier: Anyone can create these
- Still premium priced: $8.99-$11.99 (between word search and crosswords)
Recommended approach: Test market with fill-in crosswords first. If successful, invest in full crossword books.
Final Recommendations
Crossword book strategy:
- Start elsewhere: Build KDP experience with Sudoku or word search first (lower barrier)
- Test with fill-ins: Create 1-2 fill-in crossword books to test market interest
- Invest strategically: If fill-ins succeed, invest $300-$3,000 in crossword creation resources
- Quality over quantity: 1 excellent crossword book beats 5 mediocre ones
- Niche targeting: Focus on underserved niches (large print seniors, themed books) vs. competing with major publishers
Crossword puzzle books offer premium pricing and loyal buyers, but require significantly more investment than other puzzle types. For most new publishers, starting with Sudoku or word search, then testing fill-in crosswords before committing to full crossword production is the prudent path to long-term profitability.
