Using the only cloud app that lets you produce icons powered
themed Sudoku books in minutes — not months!
And a simple search on Amazon will prove it!
Sudoku puzzle books have been a top-performing category for years among buyers of all ages.
They’re simple, engaging, mentally stimulating, and highly addictive — which makes them one of the most consistently purchased puzzle formats worldwide.
What makes Sudoku so powerful is its universal appeal.
Kids enjoy it as a fun logic activity, adults use it for focus and relaxation, and seniors love it as a gentle but effective brain-exercise solution.


Teachers, parents, hobbyists, commuters, and puzzle fans all fall within this single buying audience.
And here’s the best part — Sudoku is a repeat-consumption puzzle.
Once someone starts solving it, they rarely stop at one page, one puzzle, or even one book. Completing a Sudoku only builds the desire to solve the next one.
This creates a steady, evergreen, year-round market for publishers, making Sudoku books one of the safest, most stable, and most profitable puzzle niches on Amazon KDP — with continuous demand and unlimited publishing possibilities.
While the demand is established, the supply of regular
Sudoku books on KDP makes the market crowded
They are mixing up a variety of Sudoku variants that are not only challenging but add a lot of variety for those longing for quality content in the Sudoku niche – and let me tell you there are thousands of such enthusiasts waiting to buy the right puzzle books.
You don’t have to believe me.
There’s undeniable proof that Amazon shares with us. Take a look at some of the example books below. See how they all feature Sudoku varieties that are different from the standard 9X9 grids.








And they are doing really well.
See the number of reviews and the ratings on the books above.
But then, we don’t just want you to compete with others –
we want you to annihilate the competition…
Wondering what that is?
I am going to spill the beans right here…
Most hard core Sudoku solvers want very hard Sudokus to solve.
That’s how they earn their bragging rights.
And you don’t have to take this on my face value.
Being in the trenches helps me understand the needs of our potential buyers and when I share those with you, I oftentimes have enough proof to back my statements.
Check out these random feedback collected from various Sudoku book listings on Amazon KDP.

Let’s face it.
You are not going to impress hard core Sudoku solvers with the standard 9X9 grids.
And you already know that high quality Sudoku variants are the way to go.
Think of replacing the regular numbers with placeholder icons.
It dramatically increases the difficulty, because the solver’s brain must decode each icon or symbol, map it to its underlying value and then apply Sudoku logic.
Suddenly, a familiar puzzle feels brand new again.
It becomes a hybrid Cryptogram × Sudoku experience.
A format that’s rare, exciting, and virtually unavailable on Amazon KDP.
Because this niche blends the cryptic aspect with Sudoku variants, it opens the door to entirely new publishing possibilities that most creators don’t even know exist yet.
And because this niche is massively underserved, the opportunity for you to publish premium-quality cryptic Sudoku puzzle books is enormous.
Fire up your favorite design tool, search for the right advanced grid format, generate a valid puzzle, and verify that it has exactly one unique solution. Now choose a matching icon theme, assign images or symbols in place of numbers to add an extra layer of difficulty to the puzzle. If you have the right skills it may take a few hours to get a puzzle done, but it’s not really undoable.

Now repeat that manual creation process a few hundred times to produce enough content for a complete Sudoku puzzle book. Once you have a few hundred puzzles, make sure you create the solutions for each one of them and then you are all set to move on to the next and probably the most exciting part of this process.
Once you finally assemble all the puzzles and solutions into a manuscript, upload the file to Amazon KDP and let Amazon sell, pack, ship your books to the customers and cut you a nice little royalty check month after month.

To create regular Sudoku puzzles manually, you already need PowerPoint, Illustrator, Canva, or Affinity. But to create cryptic Sudoku puzzles — where each number is replaced with a unique symbol or icon — you need even more skill. You must manage grid formatting, visual consistency, symbol alignment, and logical placement — all at once. Most indie publishers simply don’t have the design precision or visual logic mastery this niche demands.


Each puzzle involves assigning and verifying icons, ensuring logic validity, and checking that every row, column, and box follows Sudoku rules — without any visual repetition errors. Ask yourself honestly…do you really have the time, energy, or creative patience to build hundreds of visually themed, logic-correct cryptic puzzles manually? For 99% of indie publishers, the answer is a hard NO.
When you replace numbers with icons, solution creation becomes exponentially harder. You must ensure every icon is in the right place and corresponds correctly to its symbol key. One mismatch — even a single swapped icon — instantly makes your solution pages useless and destroys your book’s credibility.


Beginner Sudoku solvers might forgive a small printing or numbering error. But, hard core Sudoku solvers won’t. For them accuracy and unique solutions are non-negotiable — and will leave 1-star reviews for misaligned icons, duplicated symbols, or puzzles that can’t be solved. You don’t get a second chance in this niche — once trust is broken, it’s gone for good.
Designers who can handle Sudoku construction and visual logic using icons are rare — and they charge premium rates. Even if you pay them, you’ll still need to manually cross-check every symbol, verify every puzzle, and test every page before publishing. That means you’re paying money and losing time at the same time.


Once you start producing 100-120 page cryptic Sudoku books, you’re suddenly managing: icon mapping and puzzle creation, symbol-to-solution verification, formatting and trim-size layout and testing each puzzle for logic validity. It’s not just work… it’s stress multiplied by ten. One misaligned icon or missing symbol can ruin your entire Amazon listing overnight.
Even if you manage to build one cryptic Sudoku book manually…you can’t do 10. Or 20. Or 50. Not without a team. Not without automation. Not without hundreds of hours of trial, error, and layout corrections. That’s why big publishers dominate this niche — they have systems and design teams.


You’re not just working with numbers anymore — you’re combining symbol design, logic flow, and visual patterning. It demands precision, patience, and perfection. Unless you’re both a designer and a puzzle theorist, it’s almost impossible to pull off consistently at scale.
I can’t overemphasize the importance of having one and only one unique solution for your Sudoku puzzles. This is the most significant feature that hard core puzzle solvers need and when they don’t get it they make themselves heard. Creating these Sudokus with unique solutions manually is next to impossible.

The entire process of creating expert-level cryptic Sudoku puzzle books manually is so complex, so time-intensive, and so error-prone…that it’s virtually impossible for most indie publishers to enter this market — let alone profit from it on Amazon KDP.
Even established publishing houses are struggling in the niche which is why you won’t really find high quality icon based Sudoku books with these exotic puzzles.


This is despite the big publishing houses having…
The barrier to entry is simply too high.

Sure, you can try to manually design icon-based Sudoku puzzles — swapping numbers for symbols, ensuring every row and column follows Sudoku logic, and aligning hundreds of icons perfectly…but now that you know what it really takes, you already see the problem: It’s slow, design-heavy, logic-intensive, and absolutely unscalable. One book might be possible. A series of ten books? Forget it.

You could try hiring freelance designers or puzzle creators who understand both Sudoku logic and visual symbol placement — but the few who can do that charge premium rates. And even if you pay them, there’s no guarantee your grids are valid or your icons are mapped correctly. Which means you’ll still be stuck checking every single puzzle manually. One mismatched symbol equals 1-star review which in turn means ruined listing.

You can hire puzzle designers, graphic artists, proofers, and QA checkers…but now you’re not running a publishing business anymore — you’re running a payroll, a project-management system, and a constant quality-control cycle. And none of that is cheap.
We know this because we’re indie publishers too — and we’ve already faced every single one of the struggles you’re dealing with right now.
We’ve tried doing it all manually…
We’ve tried outsourcing…
We’ve tried managing design teams, logic testing, and endless rounds of revisions…
And all of it proved one thing:
Without the right tool, creating cryptic Sudoku books at scale is almost impossible.
That’s why we wanted to build a solution that eliminates every one of these roadblocks.


Hey, my name is Niranjan Pradhan.
I am a low content publisher on the Amazon KDP platform and I run my printables business on Etsy as well.
Along with my business partner BP Mishra, over the years we have created some high quality software apps to streamline our own publishing businesses and have extended the opportunity to our tribe to leverage the software we create to further streamline their own processes and grow their publishing businesses.
If you know me and Bings, then you already know one thing:
When we build something for the KDP community, we don’t do “basic.”
We engineer tools that completely remove the bottlenecks publishers struggle with.
We only release apps that we personally use in our own publishing business.
We’ve poured months of development into the symbol-mapping logic engine, the smart validation system, the icon library framework, and the auto-solution generator — so you can finally create visually stunning, icon-based Sudoku books without the stress, the logic puzzles, or the manual layout headaches.

And let’s be clear…
This isn’t just another “Sudoku generator.”
It’s a complete professional-grade system for producing the kind of visually cryptic, high-value Sudoku books that stand out from the sea of number-based puzzles.
Once you start using this, you’ll instantly see why we built it…

Simply put, there’s nothing else on the market that lets indie publishers create icon-based, visually cryptic Sudoku puzzles at scale — without needing design skills, coding skills, or logic expertise.
Cryptic Sudoku Puzzles Generator (CSPG) was built to solve a very specific problem for a very specific audience:
Indie publishers who want to grow their KDP business with premium-quality crossword puzzle books.

for visually engaging puzzle books at scale!
The all-time favorite among serious Sudoku fans — five overlapping 9×9 grids combined into one massive challenge. But here’s the difference: instead of numbers, each grid cell is filled with symbols or icons from your chosen library — adding a layer of visual logic that’s as fascinating as it is addictive.

And get puzzle lovers to buy from
you again and again!
Let’s be honest: the people who buy icons based Samurai and Star Sudoku books aren’t casual solvers.
They’re serious, experienced puzzle fans who crave real challenges — something fresh, something unique…something they haven’t seen a hundred times before.
That’s exactly why Cryptic Sudoku books are catching attention — they’re not just about logic; they’re about visual pattern recognition and symbol-based reasoning.
But just like with traditional Sudoku, solvers get frustrated when a book labeled “hard” turns out to be way too easy.
That’s how even beautiful puzzle books end up with reviews like:
“Too easy.”
“Finished the whole book in one sitting.”
“Not worth the money — no real challenge.”
In the expert-level Sudoku market, control over difficulty is everything.


And that’s where Cryptic Sudoku Puzzles Generator (CSPG) gives you a massive advantage.
Instead of guessing what’s “hard enough,” you control both the visual and logical complexity before your book is ever published.
With CSPG, challenge isn’t random — it’s engineered into the system.
That means no disappointed buyers — and a loyal audience that keeps coming back for harder, smarter, more engaging puzzles.

Select your cryptic Samurai or cryptic Star Sudoku template and instantly generate a fully formatted puzzle — no math, no design apps required.
Choose how challenging you want your puzzles to be by adjusting the number of visible boxes and grid logic. Hard, harder, or extreme — it’s your call.


You’re not stuck with fixed templates. Move elements, resize them, change fonts, add headings, swap instructions — you’re in full creative control.
When you create high end icon based Sudoku puzzles while it’s challenging to solve the problem which is a good thing, it can be a pain to solve as the user can’t just draw the icons to solve it. That’s when you might want to have the flexibility of showing an index where each icon is matched to a number and then subsequently the user solves the problem.

Change grid styling, fonts, text blocks, difficulty labels and more — all inside the CSPG editor. No external design software needed.
You get access to ten high quality icon sets built into the application to power the icon based Sudoku puzzles. Each set has way more than the ten you need for each number from 1 through 9 - that means more options for you to pick and choose from.

Choose from KDP-friendly trim sizes in a single click. The app formats the puzzle to fit your size automatically.
Add page numbers (or remove them) in seconds. Choose from multiple numbering styles and apply them to the entire book instantly.


The hardest part of puzzle book creation is now instant. Solutions are automatically generated and perfectly matched to each puzzle — no manual checking. You can have solutions with numbers only, icons only or as a mix of both.
Toggle print margins on and off to ensure every page is upload-ready for Amazon KDP, Etsy, Lulu, or your POD platform.


Add titles, instructions, page notes, difficulty badges — as many or as few as you like — anywhere on the page.
Publish premium-looking books with full access to a massive built-in font library. No extra licenses, no installs, no hassle.


Download puzzles or full books in ready-to-publish PDF, JPG, or PNG — great for KDP, Etsy and TPT.
Work visually with precision. Every element snaps perfectly into place on the canvas — no more eyeballing margins on the WYSIWYG editor.


Duplicate headings, instructions, icons, labels, or even the actual puzzles in one click. And it’s not just limited to the page you are working on. You can actually copy and paste elements across pages. Works on both Windows and Mac.
Created the perfect layout? Clone it, and the app will generate a brand-new puzzle on the copied page — keeping formatting intact.


Move pages up, down, or reorder your manuscript instantly — no dragging files around in Word or Google Docs.
Work at the level you’re comfortable with — whether you want a full-page view or granular detail editing.

Yes, we provide step by step video training on how to use the various features included in the Cryptic Sudoku Puzzles Generator app.
Cryptic Sudoku Puzzles Generator is a cloud based application. Therefore the software works on your computer irrespective of whether you have a PC or a Mac.
No, we recommend and test the application to work properly on Google Chrome. So if you use Google Chrome as your browser you will have no trouble using the app. In the other apps some or all features may not work as we do not test for other apps at all. Google Chrome is easy to install and free to use and chances are you are already using it to browse the internet.
In case you get stuck with the app and need help we have got you covered. We have got an extremely responsive support team waiting to help you out. On top of that we have solid communities built around our products where you will have other like minded business builders helping you out.
Yes you can, but the price may increase in the future! Also we may decide to strip down the features and retain the current price. So either way the product will be way more expensive in the future. Now is the best time to get in at the current discounted price.
Yes! There are three upgrade offers in the funnel that you will learn about after you make the front end purchase on this page. The first upgrade gives you access to pro features as described on the respective sales page. The second upgrade is a premium product that gives you access to six different rare high end and engaging Sudoku variants to help you scale your business even further. The third upgrade is a done-for-you design pack consisting of illustrations and icons that work seamlessly with the Sudoku engines. You will learn the details of what is included in each of the products on the respective sales pages that you will see after you purchase the front end product.
When you purchase the front end product, you will be taken through the funnel where you will first see the first upgrade and then you will see the second upgrade and then the third upgrade. The prices of the upgrades are mentioned on the respective sales pages
Yes, the app creates solution pages for the Cryptic Sudoku puzzles.
You don’t have to buy any of the upgrades to make the front end application work. Think of the upgrades as additional features available for a fee if you want to pick them up to make your workflow more streamlined. If you wish you can pick and choose one or more of the upgrades to add to your purchase. They are not mandatory. The only reason why we strongly recommend you take a look at the upgrades is because they are jam packed with a tremendous amount of value. And the launch price is the lowest it will ever get.
Yes! At no point in time you will be forced to make a purchase. On each of the upgrade pages you will find buy buttons that you can use to purchase the upgrade offer if you like. Likewise you will see a “No Thanks” link at the bottom of the page that you can click on to skip the upgrade and move forward in the funnel.
Because we think it is irrelevant and does not add value to our users’ experience! We do not want our customers to make a buying decision for the front end product based on the upgrade offer. We want YOU to make a buying decision of the front end based on the merit of the front end product. If you see you get enough value in exchange for your money then we would love to have you onboard. If you do not find the front end product offering value for the money then we would love to part ways and still be friends, no hard feelings!
You are probably right!
A “Download” happens when you click on any of the download buttons and that ends up downloading a single file or zipped file to your local computer. So if you create just one puzzle page and download it that would count as 1 credit used. If you create a 10 page puzzle book and download the entire book in one click then that would count as 1 download credit as well.
No! You can’t. You cannot create any content to sell on such platforms using the app.
Yes! At the moment when you are reading this the product is available for a low one time fee. However we reserve the right to increase the price without any prior notice.
With this purchase you get access to 100 downloads per month.
No. As a founding member you would get this at no cost in your dashboard.
No. As a part of your monthly puzzle apps subscription you would get access to this app in your dashboard, so you don’t need to buy this.
No. As a part of your monthly Charter membership subscription you would get access to this app in your dashboard, so you don’t need to buy this.
Yes, if you need access to the Cryptic Sudoku Puzzles app then you would have to buy it because this is a puzzle app therefore this is not included in the math membership.
Great question! As we grow we have been advised by our legal counsel to define the term “lifetime deal”, which is a good thing for us as well as our current and future customers. By “lifetime deal” it means you will get access to the app in its current shape and form for as long as the app continues to exist. On a minimum we are committed and bound to support the existing features and all buyers for the next three years after the purchase.
Yes! You can sell your books on Amazon KDP, Etsy and through your own ecommerce websites. You keep 100% of the profits. When you sell your books to the end user you sell them with personal use rights, so your customers can use the books for their personal use.

No! You can’t. This purchase allows you to create and use books where you sell those to the end user and thus make a profit from selling the books you create. You cannot sell the puzzles or puzzle books to a client who uses the assets or the book you sold for commercial use by selling them or giving them away in any shape or form.
