Shigai Royalty Review
Is This KDP Mystery Puzzle Maker Worth It?
Creating a good puzzle book for Amazon KDP is more involved than filling pages with random activities. With deduction mysteries in particular, the puzzle logic has to work, the solution needs to be unique, the clues must remain consistent, and the finished interior still has to be formatted properly for publishing.
That combination of puzzle construction and book design creates a fairly high barrier for publishers who like the mystery niche but do not want to build every case manually.
Shigai Royalty is designed to remove much of that technical work. It is a cloud-based puzzle-book creation platform from Ike Paz and Luke Bowes that generates deduction-style mystery cases, verifies that each puzzle has one logical solution, lets you customize the characters and setting, and prepares book interiors for Amazon KDP or printable marketplaces.
What caught my attention is that Shigai Royalty is not simply producing decorative puzzle pages. The deduction engine is the central part of the system. The platform is designed to check the underlying logic before a puzzle reaches the finished book, which addresses one of the biggest practical problems with creating this type of content at scale.
In this Shigai Royalty review, I will look at what is included, how the book-creation workflow operates, the optional upgrades, who should consider it, and the limitations worth understanding before purchasing.

What Is This App?
Shigai Royalty is a browser-based publishing tool built specifically around logic-driven mystery puzzles.
Instead of asking you to manually devise suspects, room positions, clues, elimination rules, solutions, hints, and formatted pages, the software handles the underlying deduction structure and then gives you controls for shaping the finished book.
The core concept resembles a location-and-suspect logic puzzle. Readers use clues and deduction to determine which character is responsible for the mystery rather than working through a traditional number-based Sudoku board.
The important distinction is the verification engine.
According to the product information, each generated board is mathematically checked so there is exactly one solution that can be reached through deduction. That matters because a visually attractive puzzle is not particularly useful if readers eventually discover that two solutions work or that the clues lead nowhere.
From a publishing perspective, Shigai Royalty combines three normally separate jobs:
- generating the puzzle logic;
- preparing the reader-facing case, hints, and solutions;
- laying those pages out for publishing.
This makes it more specialized than a general design program. Canva, PowerPoint, or another graphics application can certainly help you arrange puzzle pages, but they do not automatically construct and verify the deduction logic behind them.
Shigai Royalty also runs entirely in the cloud. The official FAQ states that there is nothing to download or install and that it works on Mac, PC, and modern browsers.
Who’s Behind The Creation?
Shigai Royalty was created by Ike Paz and Luke Bowes.
Ike Paz has previously worked on publishing-related products including Royalty Prints, Crispy Prints, Techo Royalty and Nurie Creator. His product line has generally focused on simplifying book and printable creation for people working in the self-publishing market.
Luke Bowes contributes digital product development experience, with the two creators also associated with Kuro Nazo.
Previous customer feedback around other publishing tools from the same creators can also provide some context about their track record in the KDP market. These testimonials are not reviews of Shigai Royalty itself, so I would not use them as direct proof of this product’s performance. However, they can help show that the creators have an existing user base and prior experience serving self-publishers:
Previous customer feedback from other KDP tools by the creators, included here as background on their publishing track record.
That background is relevant because Shigai Royalty is clearly built around a specific publishing workflow rather than being a general-purpose AI tool repackaged for KDP.
The software does not attempt to write every possible kind of book. Its main purpose is narrower: make deduction mystery puzzle creation easier to produce, customize, format, and export.
What’s Included In This Shigai Royalty?
The $19 front-end contains the core puzzle-generation and publishing workflow. Some of the more advanced mystery modes, artwork packs, design controls, and export formats belong to the optional upgrades, which I will cover later.
Verified Deduction Engine
This is the feature that gives Shigai Royalty most of its practical value.
Every generated puzzle is intended to have exactly one valid solution. The software constructs the case and verifies the deduction logic before the puzzle is prepared for the book.
For publishers, this removes a difficult quality-control problem.
Building one deduction puzzle manually is manageable if you understand logic-game construction. Building 40 or 100 of them while checking every possible combination becomes much harder.
Shigai Royalty automates that verification process instead of leaving publishers to test every board themselves.
Five Difficulty Levels And Flexible Grid Sizes
You can create grids ranging from 6×6 through 16×16 and choose among five solver-calibrated difficulty levels, running from Easy through Dragon.
This gives publishers more room to segment books.
You might create an easier collection for readers encountering deduction games for the first time and a separate book built around larger grids and more demanding cases.
The ability to vary difficulty also makes it easier to avoid producing a catalog where every interior feels essentially identical.
Custom Casts And Rooms
Shigai Royalty lets you personalize names, genders, character roles, room names, and portraits.
You can use available artwork or upload your own images.
That opens up more useful publishing possibilities than simply changing a book cover.
For example, the same underlying puzzle format could be adapted around:
- a Victorian house;
- a cosy village;
- holiday guests;
- a family-themed mystery;
- a wedding gift;
- a profession-specific cast.
The practical value comes from matching the presentation to a defined audience while keeping the puzzle engine underneath intact.
Custom Characters
You can also add your own character names and roles instead of relying entirely on preset suspects.
For niche publishers, this is useful because character selection can become part of the product concept rather than merely decoration.
A mystery built around bakers, hotel guests, household staff, teachers, or another themed group can feel more intentional than a generic set of suspects.
Furniture And Room Customization
Shigai Royalty also allows objects inside rooms to be changed.
What makes this more interesting than ordinary graphic customization is that the platform is described as re-verifying the puzzle after the change. You can therefore alter parts of the environment without knowingly breaking the underlying solution.
For publishers producing multiple books, this can help create visible differences between interiors while preserving the deduction structure.
Hints And Step-By-Step Walkthroughs
A difficult logic puzzle can become frustrating if readers have no way to recover after getting stuck.
Shigai Royalty addresses this with a progressive hint ladder and complete deduction walkthroughs for the solution pages.
This is one of the more reader-focused features in the package.
Instead of forcing someone to jump immediately from “I am stuck” to seeing the final answer, you can provide intermediate assistance. The walkthrough then explains how the puzzle is solved rather than merely revealing the culprit.
That makes the finished book more accessible to people learning this style of puzzle.
How-To-Solve Tutorial
The platform can insert a worked 4×4 mini-case that introduces readers to the solving process step by step.
This is especially useful if you are publishing for an audience unfamiliar with deduction grids.
A specialized puzzle book should not assume every buyer already understands its rules. Providing an instructional example before the main collection reduces that friction without requiring the publisher to design a tutorial from scratch.
Full KDP Page Designer And Bulk Mode
Shigai Royalty contains a page-design environment for preparing the interior.
Documented controls include KDP trim sizes, fonts, margins, difficulty badges, legends, puzzle-grid placement, page count, case headings, and page numbering. Bulk mode can generate a sequence of puzzles and their corresponding solution pages as one project.
This is where the software becomes more than a puzzle generator.
Generating a case is useful, but KDP publishers ultimately need a properly organized interior. Combining generation and layout means fewer manual transfers between unrelated applications.
Eight Book Languages
The front end supports:
- English
- Spanish
- French
- German
- Italian
- Portuguese
- Dutch
- Polish
The described workflow first verifies the puzzle logic and then renders the clues in the selected language.
That distinction is useful because translating the presentation should not require reconstructing the entire puzzle.
It potentially gives publishers a way to adapt an existing concept for several language markets, although translation quality should still be reviewed before publication rather than assuming every generated phrase is ready to publish unchanged.
Two Artwork Packs
The front-end offer includes two artwork packs: Illustrated and Flat Avatar.
These provide ready-made visual identities without requiring publishers to source every character portrait independently.
Additional artwork styles are associated with paid upgrades, so buyers should not assume the front-end contains every visual pack shown elsewhere in the overall product range.
Voice Control
The product information also describes voice-based controls for changing elements such as grid size, cast, theme, and difficulty.
For example, a user can request a different grid dimension or adjust the difficulty without manually changing every corresponding field.
It is a convenience feature rather than the main reason I would buy the product, but it fits the overall goal of reducing repetitive configuration.
Murder Mystery And Heist Modes
The core offer includes both murder-mystery and heist-style cases.
This gives the front end at least two different narrative directions instead of tying every project to exactly the same “find the killer” theme.
More specialized variants are reserved for Pro and Elite.
PDF And PNG Export
The front-end offer includes print-ready PDF export for paperback interiors and unlimited high-resolution PNG exports for printable products.
This allows one project to support more than one distribution format.
The PDF can be prepared for a KDP paperback, while PNG pages can be used when creating downloadable printable products for suitable marketplaces.
PPTX and SVG capabilities appear in higher-tier offers rather than being part of the basic front-end package.
Four Bonus Tools
The front end also includes four publishing-oriented bonuses:
- PDF Page Mover lets you reorder, insert, swap, or delete pages inside a PDF.
- KDP Keyword Finder is intended to assist with Amazon keyword research.
- Description Helper supports creation of book descriptions.
- QR Book Generator creates QR codes that can point readers toward another book, a website, bonus page, or other destination.
These are secondary to the deduction engine, but they make sense within a publishing workflow because they address tasks that come after the puzzle itself has been created.
How You Can Use It?
The documented workflow gives a clearer picture of Shigai Royalty than the feature list alone.
I would describe the process as configure, generate, add front matter, export, and then publish.
The demonstrated book project starts in Bulk mode. From there, the book settings are selected before generation begins.
Step 1: Select the book format
Choose the trim size for the project. In the demonstrated workflow, 8.5×11 inches was selected because the larger layout gives the puzzle grid more room.
That is not the only possible publishing strategy, but it shows that trim size is handled as part of the book-building process rather than after the puzzles have already been generated.
Step 2: Configure the mystery
Next, choose the mystery type, suspect count, and related project settings.
As the suspect count increases, the grid can become larger, so this selection affects the complexity and appearance of the finished puzzle.
Step 3: Choose the visual settings
The workflow then moves through presentation settings such as artwork treatment, color choice, floor treatment, and the case header.
For KDP publishers watching print cost, the demonstrated example specifically chose black and white rather than a color interior.
That is a practical reminder that design decisions influence publishing economics. The prettiest option is not automatically the best option for every paperback.
Step 4: Set the difficulty and page count
Choose the desired difficulty, decide how many puzzle pages to generate, and enable page numbers if required.
In the demonstrated project, 40 puzzle pages were selected. Because solution pages were also included, this created substantially more interior pages than the puzzle count alone.
Step 5: Add the project to the generation queue
Once the settings are ready, select Add to Queue.
The system then builds the puzzle pages and corresponding solutions.
This bulk step is one of the main advantages over constructing individual puzzles and layouts manually.
Step 6: Add instructions
After the main book has finished generating, an instructional/how-to-play section can be added.
This ordering matters. In the documented workflow, the book needed to finish before these additional pages were added.
Step 7: Add the copyright page
Enter the author name and create the copyright page.
That gives the interior another piece of standard front matter without requiring the publisher to leave the software and rebuild the PDF elsewhere.
Step 8: Export the interior
When everything is ready, go to Export and select Single PDF.
The completed interior can then be downloaded with the puzzle pages, solutions, copyright information, and how-to content included.
The demonstrated workflow also references a Book Cover Generator after finishing the interior. However, the clearest verified core workflow here is the interior-generation and export process, which is what I would evaluate Shigai Royalty on first.

Who Should Try Shigai Royalty?
Shigai Royalty makes the most sense for publishers who specifically want to enter or expand within puzzle and activity publishing.
Amazon KDP publishers are the most obvious audience. If you are already publishing puzzle, activity, or low-to-medium-content books, the software can add a more specialized product type to your catalog.
Beginners without puzzle-design experience may also benefit. The official FAQ specifically states that users do not need writing or puzzle-design experience because the engine generates the cases, clues, hints, and solutions.
Printable sellers can use the high-resolution PNG exports to turn puzzle pages into digital products instead of relying only on paperback sales.
Niche publishers should appreciate the cast, room, theme, and character controls because these make it easier to adapt the same underlying format to different audiences.
Publishers targeting several languages may find the eight-language support useful for repurposing a successful concept.
There are also people for whom Shigai Royalty is less compelling.
If you mainly create novels, nonfiction books, journals, or completely unrelated activity formats, this is a specialist tool and much of its value may go unused.
It is also not a substitute for market research. Generating a technically valid mystery book does not prove that customers want that theme, cover, title, keyword, or difficulty level.
And publishers looking for every advanced mode and design option inside the $19 package should review the upgrades carefully, because several of the more sophisticated features are not part of the front end.
Why Is It Worth Checking Out?
The biggest reason I think Shigai Royalty deserves consideration is that it automates the part of puzzle publishing that is genuinely difficult to reproduce with a generic design tool.
Creating a grid is easy.
Creating a grid with suspects and attractive artwork is also relatively easy.
Creating dozens of deduction puzzles where every clue remains consistent and every puzzle has precisely one defensible solution is another problem entirely.
That is where the verified deduction engine changes the workflow.
Instead of spending most of your time checking whether each case actually works, you can focus more attention on the niche, presentation, cover, title, reader experience, and overall catalog strategy.
Bulk generation adds another layer of convenience. The documented workflow shows that a publisher can configure the book once, queue dozens of pages, generate the associated solutions, add instructions and copyright material, and export a combined PDF.
The customization also matters.
If Shigai Royalty only produced one fixed murder layout with the same suspects and graphics, publishers would quickly produce books that looked interchangeable. Custom characters, rooms, furniture, difficulty, language, and visual settings give you more room to build a distinct concept around the underlying engine.
There is also some useful real-world evidence that this type of puzzle book already has buyers on Amazon. One KDP earnings screenshot for a murder-mystery puzzle title shows $312.64 in estimated royalties from 82 processed orders. That does not mean a new Shigai Royalty book will produce the same result, but it does show that mystery-puzzle titles can attract paying customers when the niche, presentation, and listing are right:
Amazon KDP earnings example for a murder-mystery puzzle title showing $312.64 in estimated royalties and 82 processed orders. Individual results vary.
Not every puzzle book produces a large result, of course. Another KDP example for a whodunit-style puzzle book shows $10.65 in estimated royalties from three processed orders. I actually think this smaller result is useful context because it shows the range of outcomes publishers can experience. Some titles may gain traction, while others may start slowly or remain small sellers:
A smaller Amazon KDP earnings example from a whodunit-style puzzle book, showing that results can vary significantly between titles.
Commercial rights are another important part of the value equation. The official FAQ states that users receive commercial rights to the books, pages, and puzzles they export.
For a $19 launch price with no recurring fee on the stated front-end offer, that creates a relatively accessible entry point for someone who already has a realistic KDP publishing plan.
A broader KDP dashboard example also shows €258.08 in estimated royalties from 88 processed orders during the selected month. Because the screenshot does not identify every title behind those orders, I would not treat this as proof of what one Shigai Royalty book can earn. It is better viewed as an example of the type of ongoing sales activity that an active KDP catalog can generate:
Example of a KDP dashboard showing €258.08 in estimated monthly royalties and 88 processed orders. This is an individual earnings example, not a typical-results claim.
The key word is publishing plan.
Shigai Royalty can simplify product creation, but it does not eliminate the work around choosing a viable niche, designing an appealing cover, writing compliant metadata, setting prices, creating a strong listing, monitoring competitors, and improving products after publication.
That is why I see it primarily as a production accelerator rather than an automatic publishing business.
The Price
Shigai Royalty is available for a $19 one-time payment during the launch period, with no recurring fee on the front-end offer. The price may increase after launch, so it is worth checking the current offer before purchasing.
The front end includes the core deduction engine, five difficulty levels, 6×6 to 16×16 grids, custom casts and rooms, eight languages, Bulk Mode, KDP page design, PDF and PNG exports, training, bonus tools, and commercial rights.
For most users, the $19 version provides enough to start creating mystery puzzle books. The optional upgrades mainly add extra puzzle variants, artwork, advanced customization, additional export options, and educational formats.
One important point: all sales are final, so there is no standard money-back guarantee.
The OTO Details
Three optional upgrades are documented.
You do not need to treat every upgrade as mandatory. The front end already contains the core deduction engine, bulk generation, customization, language support, PDF/PNG export, commercial rights, and publishing tools. The upgrades mainly broaden what types of books and designs you can produce.
OTO 1: Shigai Royalty Pro – $57
Pro expands the platform with additional puzzle styles and stronger visual customization.
It includes:
- Lying Killer and One Wasn’t There variants;
- Choose-the-Culprit mode;
- 9 kid and family modes;
- Kawaii artwork;
- premium page design;
- self-check ciphers;
- completion certificates;
- custom fonts;
- Floor Studio;
- custom furniture uploads;
- unlimited PDF and PPTX export.
This upgrade makes more sense for publishers who want to move beyond standard adult mystery books into family, gift, or youth-focused products.
OTO 2: Shigai Royalty Elite – $187
Elite is the advanced creative tier.
It adds features including:
- five premium mystery variants;
- Grand Mystery and Accomplices formats;
- IF-THEN conditional clues;
- coded cipher clues;
- 11 seasonal modes;
- a custom scenario builder;
- all 14 artwork packs;
- Elite textured styling;
- Large Print, Pocket, and Black & White edition variants;
- World Builder;
- a One-Click Story Book Wizard;
- KDP pre-flight and front-matter tools;
- additional SVG export capabilities.
Elite is more relevant to publishers planning a broad catalog than to someone who simply wants to test whether mystery puzzle books fit their business.
OTO 3: Genten Royalty – $47
Genten Royalty moves into educational math mysteries rather than simply adding more visual options to the same product.
It includes a Math Mystery Studio, support for grades 1–6, around 50 math-skill generators, 163 themes, 95 kid-safe worlds, five case generators, nine book languages, and simulation-verified cases.
This upgrade is therefore aimed more at educational and children’s publishing.
My preference for a new buyer would be to evaluate the front-end workflow first. Upgrade only when you can identify a specific publishing concept that genuinely requires one of the additional tiers.
Pros & Cons
Pros:
- The deduction engine is designed to verify one logical solution for each puzzle.
- Grid sizes from 6×6 to 16×16 provide meaningful difficulty and layout variety.
- Five difficulty levels make it possible to build books for different reader skill levels.
- Bulk generation reduces the manual work involved in assembling larger interiors.
- Custom characters, rooms, portraits, and objects support niche-specific book concepts.
- Progressive hints and walkthroughs improve the experience for readers who become stuck.
- The how-to-solve tutorial helps onboard complete beginners.
- Eight supported book languages provide options beyond English-only publishing.
- Print-ready PDF and high-resolution PNG exports support both paperbacks and printables.
- Commercial rights are included with exported content.
- The core offer has no stated recurring fee.
- Four bonus publishing tools extend the workflow beyond puzzle generation.
Cons:
- Shigai Royalty is highly specialized, so it is not a general KDP book creator.
- Some desirable mystery modes, kid-focused formats, artwork packs, PPTX export, SVG tools, and advanced design controls require paid upgrades.
- The $19 price is a launch price and is stated to increase after launch.
- Sales are final, so there is no standard money-back trial period.
- Users still need to research niches, create competitive listings, follow marketplace rules, and make sensible publishing decisions.
- Publishers should review generated text, translations, layouts, and final files before uploading rather than treating automation as a replacement for quality control.
Another important publishing consideration comes from the documented training: users are specifically warned not to use the term “Murdoku” in book titles, subtitles, descriptions, or keyword slots. The recommendation is to avoid that terminology and use an appropriate generic description of the puzzle instead.
That is an important reminder that commercial rights to generated content do not remove a publisher’s responsibility to handle trademarks, metadata, and marketplace compliance carefully.
Is Shigai Royalty Legit?
Shigai Royalty presents a coherent and demonstrable workflow rather than merely a collection of broad promotional promises.
The core creation process can be traced from choosing the book format and puzzle settings through bulk generation, adding instructions and copyright information, and exporting a combined PDF interior.
The front-end inclusions are also clearly separated from the optional Pro, Elite, and Genten Royalty upgrades. That makes it easier to understand what the initial $19 purchase is meant to include.
There are still realistic boundaries.
A verified puzzle does not equal a profitable book.
Shigai Royalty cannot guarantee that a niche has enough demand, that your book will rank on Amazon, that a cover will convert browsers into buyers, or that a particular publishing strategy will earn royalties.
Those outcomes depend on market selection and execution beyond the puzzle generator itself.
The refund policy is also less buyer-friendly than products offering a 30-day trial period. Official information states that purchases are final because access to the software, training, and bonuses is provided immediately.
Buyers should therefore look carefully at the feature set before purchasing rather than relying on the possibility of testing it and requesting a refund later.
Final Verdict
Shigai Royalty addresses a very specific publishing problem, and that specialization is probably its greatest strength.
It does not try to be an all-purpose AI book creator.
Instead, it focuses on building deduction mystery puzzles, checking that their logic works, giving publishers ways to customize the reader experience, and packaging those puzzles into files that can be used for KDP paperbacks or printable products.
The verified deduction engine is the most meaningful part of the package. Without that, Shigai Royalty would largely be another collection of puzzle templates and page-design controls.
With it, the software can remove a genuinely difficult part of creating this type of book manually.
I also like the way the core workflow connects puzzle generation with hints, solution walkthroughs, tutorial pages, bulk generation, page formatting, and PDF export. Those functions solve adjacent problems rather than simply adding unrelated features.
The $19 launch price makes the front end particularly interesting for KDP publishers who already understand that book creation is only one part of the business. Commercial rights, eight languages, bulk mode, custom characters, and no stated recurring fee strengthen the value of that entry package.
The main reservations are straightforward.
It is a niche tool. Several of the more advanced formats and design features require additional purchases. And there is no money-back guarantee.
For someone with no interest in puzzle publishing, there is little reason to buy it.
For a KDP or printable publisher who specifically wants to create deduction mysteries without manually engineering every case, however, Shigai Royalty offers a much more focused solution.
My preferred approach would be to start with the core package, create one carefully researched book concept, inspect every page and solution, validate the final listing and metadata, and only consider Pro, Elite, or Genten Royalty when there is a clear reason to expand.
Overall, Shigai Royalty is worth considering for publishers who want a specialized, logic-verified way to produce customizable mystery puzzle books while reducing much of the manual construction and formatting work.
