"Pocket Sudoku": 58K Searches, 100% Indie, One Big Winner
"Pocket sudoku" draws 58,046 monthly searches and 100% indie books. One title earns $15,350/mo; most chart with 0 reviews. See the angle.
The search phrase "pocket sudoku" gets 58,046 searches a month, up 402% from last month, and every charting book with the phrase in its title is independently published. That is an unusual opening for a low-content publisher. The demand is real and growing; the supply is not yet crowded by traditional houses.
The catch is that one book takes most of the money. Pocket Sudoku & Aesthetic Ink Tracing by Hoso Enzo is estimated at 960 units and $15,350 a month. The next best sellers earn $1,367 and $1,349. The keyword is not a lottery ticket, but it is a small, clearly defined market where a good cover and the right angle can still get traction.
Search demand is huge and still climbing
Monthly searches for "pocket sudoku" reached 58,046 in September 2026. That is up 401.7% from the previous month and 1,929.6% from a year earlier. The purchase rate is 2.5%, which works out to about 1,463 monthly purchases.
Those purchase numbers are modelled from search volume, not reported by Amazon, so treat them as a direction rather than a ledger. The direction is clear: this is a phrase people type when they want a small sudoku book, often for travel or a bag. The related suggestions confirm it: "pocket sudoku and ink tracing" and "pocket posh sudoku" both appear alongside the main term.
For a publisher, a 402% month-over-month jump can mean a seasonal spike or a new trend. The year-over-year number is large enough that it is not just one month's noise. Still, the data does not tell us why the searches rose, only that they did.
Competition: 1,328 products, but a low review barrier

There are 1,328 competing products for this phrase, a supply-demand ratio of 43.7. That ratio is searches per product, so a higher number is better for sellers. At 43.7, the phrase has more demand than the shelf depth suggests.
The review data explains why. Of the charting books analyzed, five have zero reviews and two have between 1 and 9. Only one book has 50 to 199 reviews, and one has 200 to 999. The median reviews across the analyzed books is 1. That is the barrier a new book has to clear: almost nothing.
That does not mean reviews do not matter. The top earner, Pocket Sudoku & Aesthetic Ink Tracing, has 60 reviews and a 4.2 rating. The lowest-priced charting book, Pocket Sudoku by Bonfire Publishing at $6.99, has 206 reviews and a 4.8 rating, but it is estimated at only 66 units a month. Reviews help conversion, but price and positioning seem to matter more here.

Where these books chart: Math Games, Travel Games, Sudoku
Show the data
| Category | Books |
|---|---|
| Math Games | 18 |
| Travel Games | 10 |
| Sudoku | 10 |
The charting books sit in three categories: Math Games (18), Travel Games (10) and Sudoku (10). Those counts are books per category, not sales, but they show where the phrase has traction.
Travel Games is the useful signal. "Pocket" implies portability, and a book that is genuinely 4 x 6 inches fits that category honestly. Math Games is a broader shelf where puzzle books compete with educational titles. Sudoku is the obvious home, but it is also where the phrase is most expected, so differentiation has to come from format or price.
If you publish into Travel Games, make the trim size visible in the title and on the cover. The Bonfire book does this with "Only 4 x 6 Inches in Size" and "Small in Size, Big in Fun." The phrase is doing the work of a keyword and a promise.
Price: the median is $11.99, but the top seller charges $15.99

The average price across the analyzed books is $11.99, and the median is also $11.99. The price ranges chart shows two books between $5 and $9.99, three between $10 and $14.99, and one between $15 and $19.99. Nothing is below $5 or above $20.
The top earner, Pocket Sudoku & Aesthetic Ink Tracing, is priced at $15.99 and still moves an estimated 960 units a month. That is unusual for a puzzle book. It bundles 100 medium sudoku puzzles with ink-tracing illustrations, which gives it a second use case and a reason to charge more.
The $11.99 cluster is crowded. Ana Shrimp has two books there, Aesthetic Pocket Sudoku at medium-to-hard and easy-to-medium, and Create Calm has Pretty Pocket Sudoku - Easy at $9.99. If you enter at $11.99, you are competing on cover and title, not price.

Estimated monthly revenue for the top book is $15,350, based on its sales rank of 605. The next books earn $1,367 and $1,349. That is a steep drop. The keyword has one clear winner and a long tail of small sellers.
The winning title is Pocket Sudoku & Aesthetic Ink Tracing: Volume 1 | 100 Medium Sudoku Puzzles & Ink-Tracing illustrations for Focus, Creativity & Mindfulness. It is a mouthful, but every part is a keyword: pocket, sudoku, aesthetic, ink tracing, medium, mindfulness. The related suggestion "pocket sudoku and ink tracing" shows people are already searching that combination.
The author, Hoso Enzo, is publishing under a KDP account. The book has 60 reviews, which is far above the median of 1. That review count did not appear overnight, but it is not an impossible wall either. The lesson is not to copy the title exactly; it is that a second activity can justify a higher price and a broader search footprint.
New releases are still finding room
Two of the analyzed books are new releases from September 2026. Pretty Pocket Sudoku: Progressive Hard Logic Puzzles by Marie Therese published on September 11 and has a rank of 1,279,586, estimated at 3 units a month. The easy volume published on September 3 and has no rank data in this set. A third new release, Pocket Sudoku Puzzle Book for Adults by Mr Alex Liam, published in September 2025 and has a rank of 2,154,371, estimated at 0 units.
These are not breakout numbers. They are early. A book published two weeks ago will not have reviews or rank history. The data cannot tell us whether they will climb. What it does show is that new books are entering the phrase, and the review barrier is low enough that a new title can chart without a review history.
If you publish a new pocket sudoku book, plan for the first month to be quiet. The top book has 60 reviews; the median is 1. The gap is time, not magic.

How to angle a new pocket sudoku book
Start with the format. "Pocket" is the promise. A 4 x 6 inch trim size is the standard in this set, and the Bonfire book makes it explicit in the title. If your book is 6 x 9, it is not a pocket book, and the keyword will disappoint buyers.
Then pick a second hook. The top earner adds ink tracing. Ana Shrimp adds "aesthetic" and progressive difficulty. Create Calm adds a design series name, the Blue Bauhaus Series. Marie Therese adds "screen-free brain games" and volumes. The phrase alone is not enough to stand out on a shelf of 1,328 products.
Price around the median at $11.99 unless you have a bundle that justifies $14.99 or $15.99. The $6.99 book with 206 reviews is not the volume leader, so low price is not the winning move here. And put the phrase in the title exactly: "pocket sudoku" appears in every charting title, and the related searches are variations on it.

FAQ
Is "pocket sudoku" a good keyword for a new KDP book?
Yes, if you can publish a genuinely small book. The phrase gets 58,046 monthly searches and every charting title is indie. The median review count is 1, so a new book can chart without a review history.
How much money do pocket sudoku books make?
Estimates from sales rank show a wide range. The top book earns about $15,350 a month, but the next books earn $1,367 and $1,349, and several new releases are estimated at 3 units or fewer. The average is pulled up by one winner.
What price should I charge for a pocket sudoku book?
The median price is $11.99, and most charting books sit between $10 and $14.99. The top earner charges $15.99 because it bundles ink tracing. A $6.99 book with 206 reviews is estimated at only 66 units a month, so low price is not the advantage.
Which categories should a pocket sudoku book be listed in?
The charting books appear in Math Games, Travel Games and Sudoku. Travel Games fits the pocket format best, and Sudoku is the expected home. Use both, and make the trim size clear in the title.
