The 12 Puzzle Book Types Ranked
1. Sudoku (★★★★★ Best Overall)
| Metric | Rating | Details |
|---|---|---|
| Competition | Medium | 10,000+ books but high demand absorbs supply |
| Profit Potential | Very High | $8-$12 price point, strong series sales |
| Creation Difficulty | Easy | Automated generators, no themes needed |
| Repeat Purchase | Excellent | Buyers purchase 3-10 books annually |
Why it wins: Universal appeal, language-agnostic, endless variations by difficulty level. Top publishers earn $20K-$50K/month with Sudoku portfolio. Best for series building.
2. Word Search (★★★★☆ Excellent)
| Metric | Rating | Details |
|---|---|---|
| Competition | High | 30,000+ books, but niche themes break through |
| Profit Potential | High | $6-$10 typical, volume sales compensate |
| Creation Difficulty | Easy-Medium | Needs theme research, generators available |
| Repeat Purchase | Good | Buyers purchase 2-5 books annually |
Why it's profitable: Theme-based differentiation allows niche dominance (dog lovers, travel, Bible verses). Large print versions for seniors are highly profitable sub-niche.
3. Crossword Puzzles (★★★☆☆ Good)
| Metric | Rating | Details |
|---|---|---|
| Competition | Very High | Dominated by established publishers |
| Profit Potential | Medium | $7-$10, harder to differentiate |
| Creation Difficulty | Hard | Requires quality clue writing, time-intensive |
| Repeat Purchase | Excellent | Loyal buyers, high consumption rate |
Challenge: Quality crosswords are hard to create. Automated generators produce poor-quality clues. Best for publishers willing to invest time in manual curation or hire puzzle creators.
4. Mazes (★★★★☆ Excellent for Kids)
| Metric | Rating | Details |
|---|---|---|
| Competition | Low-Medium | Under-served compared to other types |
| Profit Potential | High | $6-$9, strong gift market |
| Creation Difficulty | Easy | Generators available, themed variations |
| Repeat Purchase | Medium | Parents buy 1-3 books per child annually |
Sweet spot: Kids ages 4-10. Add coloring elements for double value. Themed mazes (dinosaurs, princesses, vehicles) perform exceptionally well.
5. Logic Puzzles / Brain Teasers (★★★★☆ Excellent)
| Metric | Rating | Details |
|---|---|---|
| Competition | Low | Niche audience, limited quality books |
| Profit Potential | Very High | $9-$14, premium pricing accepted |
| Creation Difficulty | Medium-Hard | Requires puzzle design skills or sourcing |
| Repeat Purchase | Good | Enthusiasts buy multiple books |
Types include: Number sequences, pattern recognition, lateral thinking, Kakuro, KenKen. Target audience is highly engaged and willing to pay premium prices.
6. Coloring Books (★★★★☆ Excellent for Specific Niches)
| Metric | Rating | Details |
|---|---|---|
| Competition | Very High | Saturated, but niches still profitable |
| Profit Potential | Medium-High | $6-$12 depending on complexity |
| Creation Difficulty | Medium | Need artwork or AI generation skills |
| Repeat Purchase | Medium | 1-2 books per buyer |
Profitable niches: Swear word coloring (adults), mandala (stress relief), specific animals (dogs, horses), occupation-based (nurses, teachers). Avoid generic "adult coloring books."
7. Dot-to-Dot (★★★☆☆ Good for Kids)
| Metric | Rating | Details |
|---|---|---|
| Competition | Medium | Moderate supply, consistent demand |
| Profit Potential | Medium | $5-$8, strong educational angle |
| Creation Difficulty | Easy-Medium | Need illustration skills or software |
| Repeat Purchase | Low-Medium | Parents typically buy 1 book |
Best approach: Combine with coloring (dot-to-dot reveals image, then color it). Target ages 3-8. Themed books (animals, vehicles, holidays) perform better than generic.
8. Cryptograms (★★★☆☆ Niche but Loyal)
| Metric | Rating | Details |
|---|---|---|
| Competition | Low | Small market but underserved |
| Profit Potential | Medium | $6-$9, niche pricing power |
| Creation Difficulty | Easy | Quote selection + encryption software |
| Repeat Purchase | Very Good | Dedicated fans buy multiple books |
Content angle: Famous quotes, Bible verses, motivational sayings. Themed collections (Mark Twain quotes, Churchill quotes) can dominate tiny sub-niches.
9. Picture Puzzles / Spot the Difference (★★★☆☆ Good)
| Metric | Rating | Details |
|---|---|---|
| Competition | Medium | Moderate market saturation |
| Profit Potential | Medium | $6-$10, visual appeal drives sales |
| Creation Difficulty | Medium-Hard | Need photo editing skills or AI tools |
| Repeat Purchase | Medium | Casual buyers, 1-2 books |
Creation tip: Use royalty-free photos, create duplicates, add/remove small details using Photoshop or GIMP. Kids versions perform better than adult versions.
10. Fill-In Puzzles (★★☆☆☆ Moderate)
Competition: Low | Profit Potential: Low-Medium | Difficulty: Hard
Similar to crosswords but with word bank provided. Easier for solvers but harder to create quality puzzles. Small but dedicated audience. Not recommended for beginners.
11. Jumbles / Anagrams (★★☆☆☆ Niche)
Competition: Low | Profit Potential: Low | Difficulty: Easy
Easy to create but limited market appeal. Works better as part of mixed puzzle books rather than standalone. Consider including jumbles as bonus content in word search books.
12. Number Search (★★★☆☆ Underrated)
Competition: Very Low | Profit Potential: Medium-High | Difficulty: Easy
Hidden gem opportunity! Like word search but with numbers (phone numbers, dates, sequences). Appeals to number-oriented people. Very low competition makes it worth exploring.
