What if you could create an entire mystery puzzle book without having to write complicated mysteries, design logic grids, or spend weeks making sure every puzzle actually works?

Puzzle books have long been a popular category in self-publishing. Word searches, Sudoku books, coloring books, and activity books can all be found across Amazon.
But that also creates a challenge.
How do you create something different enough to stand out?
Shigai Royalty takes an interesting approach by helping publishers create story-driven whodunit logic puzzle books, complete with suspects, clues, mystery grids, hints, and solutions.
And instead of manually constructing every mystery yourself, the software handles much of the complicated work for you.
What Is Shigai Royalty?
Shigai Royalty is a cloud-based puzzle creation system designed for people who want to publish mystery logic puzzle books through Amazon KDP or sell them as downloadable printables.
The concept combines the appeal of a murder mystery with the logical problem-solving experience of a puzzle.
Readers are presented with suspects, rooms, clues, and a mystery to solve.
They then use deduction to determine what happened and identify the culprit.
Sounds like something that would take a lot of work to create, doesn’t it?
Normally, it could.
That’s where the software comes in.
Create Mystery Puzzles Without Writing Them by Hand
One of the biggest challenges with creating logic puzzles is making sure they actually have a valid solution.
Every clue has to work with every other clue.
If something is wrong, the reader could reach a dead end or discover that more than one solution is possible.
Shigai Royalty uses a verified deduction engine to generate the puzzle and check that it has one solution.
You choose options such as the difficulty, grid size, characters, and rooms, and the system generates the case.
It can also create the clues, hints, and step-by-step solution walkthrough.
That means you don’t necessarily need to be a mystery writer or puzzle designer to experiment with this type of publishing.
Choose From Different Difficulty Levels
Not every puzzle reader wants the same experience.
Some people want something relaxing that they can solve fairly quickly. Others want a puzzle that makes them sit there scratching their head for an hour.
Shigai Royalty offers five difficulty levels, ranging from Easy through its highest “Dragon” level.
Grid sizes can range from 6×6 up to 16×16, allowing you to create books for different types of puzzle solvers.
That also opens up an interesting possibility.
Instead of creating just one book, you could potentially develop a series that gradually moves from easier puzzles toward more difficult challenges.
Turn Your Puzzles Into Complete Books
Creating the puzzle itself is only part of publishing a puzzle book.
You still need pages that are properly formatted for printing.
Shigai Royalty includes a page designer with support for popular Amazon KDP trim sizes, margins, fonts, difficulty indicators, legends, and other formatting elements.
There’s also a bulk-generation feature designed to help create multiple puzzles for an entire book.
Once you’re satisfied with the project, you can export print-ready PDF files or high-resolution PNG images.
That gives you the flexibility to use the content for Amazon KDP paperbacks as well as downloadable printable products.
Create Different Types of Mystery Books
Do all the books have to be murder mysteries?
No.
The system also includes a Heist mode that allows you to create “find the thief” style puzzles.
You can customize characters and room names, which opens the door to creating different themes and settings.
You might build mysteries around a mansion, a cruise ship, an office, a haunted hotel, or another setting that fits the audience you’re trying to reach.
There are also possibilities for personalized mystery books using custom names and photos.
Instead of publishing essentially the same puzzle book repeatedly, you can use the underlying system to explore different audiences and themes.
Reach Readers in Multiple Languages
Another interesting feature is multilingual publishing.
Shigai Royalty supports books in eight languages: English, Spanish, French, German, Italian, Portuguese, Dutch, and Polish.
That can potentially allow publishers to explore markets beyond English-language Amazon customers without manually recreating every puzzle from scratch.
Of course, publishing in another language still requires careful review. But having multilingual capabilities built into the creation system gives publishers more options when deciding where and how to distribute their books.
Sell Books or Create Digital Printables
Amazon KDP isn’t the only possible use for the content you create.
Because Shigai Royalty can export high-resolution images as well as print-ready files, the puzzles can also be packaged as downloadable printables.
That could include mystery puzzle packs, party activities, game-night material, classroom brain teasers, or other digital products.
The software includes commercial rights for the books and puzzle products you create.
So instead of being limited to one publishing platform, you can potentially repurpose the same underlying content for different types of products.
Could Mystery Puzzle Books Be an Interesting Publishing Niche?
There’s never a guarantee that a particular book or publishing niche will make money.
Success still depends on factors such as the quality of the finished product, niche selection, presentation, keywords, pricing, competition, and whether customers actually want what you’re offering.
But tools like Shigai Royalty can remove one significant obstacle: the technical difficulty of creating the puzzles themselves.
Instead of spending weeks manually constructing and checking logic puzzles, you can focus more of your attention on the finished book, the audience, and how you want to position it.
And that can make experimenting with a more specialized publishing niche much more accessible.
Turn a Mystery Idea Into a Publishable Product
Self-publishing doesn’t always have to mean sitting down and writing a 200-page book.
Sometimes the opportunity is in creating something people simply enjoy using.
Mystery puzzles combine storytelling, deduction, problem-solving, and entertainment into a format that can work as both a physical book and a digital printable.
Shigai Royalty provides the technology to help turn that idea into an actual finished product.
If you’ve been looking for a different type of Amazon KDP or printable publishing project, particularly something beyond the usual word searches and Sudoku books, this could be an interesting niche to explore.
