What Is Shigai Royalty?
Shigai Royalty is a cloud-based puzzle-book creation engine focused on Murdoku-style whodunit logic puzzles. Instead of manually inventing a mystery, creating a logical puzzle, checking whether it can actually be solved, and then formatting dozens of pages yourself, you configure the case and let the engine generate it.
A typical puzzle can include:
A cast of suspects
Different rooms
A mystery or crime
Logic clues
A deduction grid
Hints
A step-by-step solution
KDP-ready page formatting
The software supports five difficulty levels, from Easy through "Dragon," and grid sizes from 6×6 through 16×16. Most importantly, the engine mathematically verifies each puzzle to ensure there is exactly one solution.
That verification is a big deal. When you're making logic puzzles manually, a tiny mistake in one clue can create multiple possible solutions or make the puzzle impossible to solve. Shigai Royalty is specifically designed to deal with that problem.
How Does Shigai Royalty Work Step by Step?
➤ Step 1: Create Your Mystery
You start by selecting your settings. You can choose the difficulty, grid size, suspects, rooms, and other elements of the case. The engine then generates the puzzle, clues, hints, and solution walkthrough while checking the logic.
Recent additions also allow voice control, so users can give commands such as changing the grid size, number of suspects, theme, or difficulty.
➤ Step 2: Customize the Case
You're not restricted to whatever names or settings the software initially provides. The system supports custom characters, custom rooms, photo uploads, and different visual styles. You can even change objects inside rooms, with the engine re-verifying the puzzle afterward.
That opens up some interesting possibilities for themed books. For example, you could create Victorian mansion mysteries, office mysteries, cruise-ship cases, haunted hotel adventures, or other custom worlds.
➤ Step 3: Build the Book
Once your puzzles are generated, Shigai Royalty's page designer handles the book formatting. The system includes margins, fonts, KDP trim sizes, difficulty badges, legends, and other layout elements. Bulk mode can also generate an entire book in one pass.
➤ Step 4: Export
You can export print-ready PDFs as well as unlimited high-resolution PNG files. That means the same basic content can be used for physical KDP books or digital printable products.
➤ Step 5: Publish and Sell
The intended publishing routes are Amazon KDP and printable marketplaces. For KDP, Amazon handles printing and fulfillment. For printable products, you can sell the exported files as digital downloads.
About The Creator
Shigai Royalty comes from the collaboration of Luke Bowes, the digital product innovator behind the technology, and Ike Paz, an experienced KDP publisher, online marketer, and entrepreneur.
Ike Paz, founder of Crispy Prints, has built experience around creating and selling printables, KDP books, POD products, courses, and software. But like many publishers, he ran into a frustrating problem: the most obvious KDP niches were already packed with competition.
Categories such as sudoku, coloring books, and other traditional puzzle formats were becoming increasingly difficult to break into. Publishing another book in these crowded markets could mean ending up deep in Amazon's search results, surrounded by thousands of similar titles. That's where the idea behind Shigai Royalty came from.
And Shigai Royalty isn't their only project. Their product portfolio includes tools and publishing-focused products such as KuroNazo, Techo Royalty, Sansuu Royalty, Manaka Royalty, Ohanashi AI Gen, Shohin Press, Nurie Creator, and Kawaii Town Prints, among others.
Shigai Royalty Review - Key Features
✅ Verified Deduction Engine
At the heart of Shigai Royalty lies its unique deduction engine. Every puzzle is mathematically generated and verified to ensure exactly one solution. This eliminates the risk of broken puzzles, frustrated buyers, or one‑star reviews. Unlike human‑made puzzles that can easily contain errors, the engine guarantees logical consistency every time.
✅ Multiple Difficulty Levels
Shigai Royalty offers five solver‑calibrated difficulty levels, ranging from Easy to Dragon. This allows publishers to create books that appeal to both casual solvers and hardcore puzzle enthusiasts. Difficulty ladders also encourage repeat purchases, as readers progress from beginner volumes to advanced challenges.
✅ Custom Casts & Rooms
Personalization is a major selling point. Publishers can customize suspects, upload photos, assign genders, and rename rooms. This flexibility enables niche‑specific books — from office mysteries to cruise‑ship capers — ensuring every book feels unique and tailored to its audience.
✅ Hints & Walkthroughs
Every puzzle comes with a hints ladder and a step‑by‑step solution walkthrough. This ensures solvers never get stuck, protecting reviews and encouraging buyers to finish the book. A smooth solving experience translates into higher satisfaction and repeat purchases.
✅ Multi‑Language Support
Shigai Royalty supports eight languages: English, Spanish, French, German, Italian, Portuguese, Dutch, and Polish. This opens up multiple Amazon marketplaces, allowing publishers to reach international audiences without additional translation costs.
✅ Artwork Packs
Two complete visual identities are included:
Illustrated Pack for a classic, detailed look
Flat Avatar Pack for a clean, modern style
Publishers can switch between styles depending on niche or audience preference, giving books a professional finish from day one.
✅ Voice Control
A newly added feature, voice control allows users to issue spoken commands like:
“Make it a 9×9 grid.”
“Six suspects, Victorian manor.”
“Bump the difficulty to hard.”
The engine adapts instantly, streamlining workflow and saving time.
✅ Custom Characters
Users can type names and assign roles to suspects, creating casts that fit specific niches. Whether it’s cozy village bakers, Victorian staff, or holiday guests, publishers can tailor puzzles to match buyer interests.
✅ Swap the Furniture
Every object in every room can be changed — armchairs, wardrobes, pianos, trunks. The engine instantly re‑verifies the puzzle to ensure the solution remains valid. This feature adds creative freedom without compromising logic.
✅ Flexible Exports
Shigai Royalty outputs both print‑ready PDFs and unlimited PNGs, making it easy to publish on Amazon KDP or sell as printables on platforms like Etsy. This dual income stream maximizes earning potential.
✅ Full KDP Page Designer
The built‑in designer handles margins, fonts, trim sizes, difficulty badges, and legends. Bulk mode allows entire books to be generated in one pass, eliminating formatting headaches and saving hours of manual work.
✅ Launch Bonuses
During the launch window, buyers receive several valuable bonuses:
PDF Page Mover (reorder or edit interiors)
KDP Keyword Finder (fill all 7 keyword slots with real buyer searches)

How Much Does Shigai Royalty Cost?
❤️ Shigai Royalty Front End ($19)
When I purchased Shigai Royalty, I paid $19 as the launch price. For what I was looking to do, I thought that was a reasonable entry point. What I liked most was that I didn't need to commit to another expensive monthly software subscription just to test the concept. The $19 price gave me a chance to experiment with the system and see whether this type of puzzle publishing would fit into my own workflow.
Of course, the software itself isn't the investment that determines whether you'll make money. You'll still need to research your niche, create appealing covers, optimize your Amazon listings, and actually publish and promote your books.
My Recommendation
After using Shigai Royalty, I'd say it's worth considering if you're already interested in KDP, puzzle books, or printable products and want something a little different from the usual sudoku, word-search, and coloring-book approach.
I especially like the idea of being able to create a series rather than relying on a single book. You can experiment with different mystery themes, difficulty levels, characters, and formats, then see which ones your audience responds to.
At $19, I personally think it's a fairly easy tool to test if you're serious about exploring this niche. I wouldn't buy it expecting automatic royalties, but if you're willing to put in the work of researching, publishing, and improving your books, the production system can potentially save you a lot of time.

Why Should You Choose Shigai Royalty?
My Personal Experience With Shigai Royalty:
I decided to test Shigai Royalty with a small project called Mystery Shelf Studio. I wanted to see whether I could actually use the software to create a small, consistent catalog and get some real sales data.
I started by creating a series of mystery logic puzzle books with different difficulty levels and themes. The books included suspects, rooms, clues, deduction grids, hints, and solution walkthroughs. I also experimented with different covers and titles instead of making every book look like a clone of the previous one.
The part that saved me the most time was the puzzle generation itself. Normally, creating a logic puzzle means coming up with the scenario, figuring out the relationships between suspects and locations, writing the clues, testing the solution, and then checking everything again. One mistake can completely break the puzzle.
With Shigai Royalty, I could configure the case and let the system generate and verify the puzzle. I still reviewed the finished pages before publishing, but I wasn't spending hours trying to construct every deduction manually.
Death at the Grand Hotel
Case File
A storm has trapped six guests inside the elegant Grand Hotel. At 11:45 PM, hotel owner Arthur Blackwell is discovered dead inside the Ballroom. The doors were locked from the inside, and only six people were known to be in the hotel that evening. Each suspect was in a different room when the incident occurred. Your job is to determine where each suspect was standing when the crime happened — and ultimately identify the person who was in the Ballroom.
The Suspects
Amelia Hart — A famous novelist staying at the hotel for a quiet weekend. She claims she spent the evening alone.
Benjamin Cole — A wealthy businessman and longtime acquaintance of Blackwell. He insists he was making a phone call.
Clara Finch — A private art dealer who had argued with Blackwell earlier that evening.
Daniel Reed — The hotel's mysterious night manager. He says he was checking the upper floors.
Evelyn Price — A journalist investigating rumors surrounding the hotel.
Felix Grant — A stage magician performing at the Grand Hotel that weekend. He claims he was preparing for the next night's show.
The Six Rooms
Lobby — The hotel's grand entrance and reception area.
Library — A quiet room filled with antique books and old records.
Ballroom — The location where Arthur Blackwell was discovered.
Dining Room — The hotel's formal dining area.
Conservatory — A glass-walled room overlooking the gardens.
Rooftop — The hotel's upper observation terrace.
Each suspect was in exactly one room, and no two suspects occupied the same room.
The Clues
Clue 1: The three women — Amelia, Clara, and Evelyn — were in the Library, Dining Room, and Conservatory, one woman in each room.
Clue 2: Daniel Reed was on the Rooftop.
Clue 3: Benjamin Cole was in the Lobby.
Clue 4: Evelyn Price was not in the Conservatory.
Clue 5: Amelia Hart was not in the Library.
Clue 6: Clara Finch was not in the Conservatory.
Clue 7: Evelyn Price was not in the Dining Room.
Clue 8: Felix Grant was not on the Rooftop.
Clue 9: The person in the Ballroom was a man.
Clue 10: Neither Benjamin Cole nor Daniel Reed was in the Ballroom.
Deduction Grid
Use ✓ for a confirmed match and ✗ for an impossible match.
Suspect | Lobby | Library | Ballroom | Dining | Conservatory | Rooftop |
Amelia Hart | ||||||
Benjamin Cole | ||||||
Clara Finch | ||||||
Daniel Reed | ||||||
Evelyn Price | ||||||

Hint Ladder
The hints are designed so readers can ask for help without immediately giving away the answer.
Hint 1 — Gentle: Start with the clues that give you an exact room immediately.
One clue tells you exactly where Daniel was, and another tells you exactly where Benjamin was.
Hint 2 — Getting Warmer: Once you place Daniel and Benjamin, look at the three women. Clue 1 tells you that Amelia, Clara, and Evelyn must occupy the Library, Dining Room, and Conservatory.
Hint 3 — Narrow It Down: Evelyn cannot be in the Conservatory or Dining Room. Which of those three women's rooms is left for her?
Hint 4 — Almost There: Once Evelyn's room is identified, look at Amelia and Clara. Amelia cannot be in the Library, while Clara cannot be in the Conservatory. That should leave only one possible arrangement.
Hint 5 — Final Deduction: After placing the three women, Daniel, and Benjamin, only one room remains for Felix. Now look at the location of the victim. Who was in the Ballroom?
Solution Walkthrough
Step 1 — Place Daniel: Clue 2 tells us: Daniel Reed → Rooftop. Mark Daniel's Rooftop square with ✓ and eliminate every other room for Daniel with ✗.
Step 2 — Place Benjamin: Clue 3 gives us another definite placement: Benjamin Cole → Lobby. Benjamin therefore cannot be in any of the other five rooms.
Step 3 — Focus on the Three Women: Clue 1 is the key structural clue. Amelia, Clara, and Evelyn must occupy: Library, Dining Room, Conservatory. There is exactly one woman in each. That means none of these three women can be in the Lobby, Ballroom, or Rooftop.
Step 4 — Solve Evelyn's Location: We know from Clue 4: Evelyn is not in the Conservatory. Clue 7 tells us: Evelyn is not in the Dining Room. The women can only be in the Library, Dining Room, and Conservatory. If Evelyn can't be in the Dining Room or Conservatory, there is only one possibility: Evelyn Price → Library
Step 5 — Solve Amelia's Location: Clue 5 tells us: Amelia is not in the Library. The Library is already occupied by Evelyn anyway. The remaining rooms for Amelia and Clara are: Dining Room, Conservatory. Clue 6 tells us: Clara is not in the Conservatory. Therefore: Clara Finch → Dining Room. And the remaining women's room must belong to Amelia: Amelia Hart → Conservatory
Step 6 — Place Felix: We now have:
Suspect | Room |
Amelia Hart | Conservatory |
Benjamin Cole | Lobby |
Clara Finch | Dining Room |
Daniel Reed | Rooftop |
Evelyn Price | Library |
Felix Grant | Ballroom |
Every room is now occupied exactly once. Felix must therefore have been in the Ballroom.
Final Solution: The Complete Deduction Grid
Suspect | Lobby | Library | Ballroom | Dining | Conservatory | Rooftop |
Amelia Hart | ✗ | ✗ | ✗ | ✗ | ✓ | ✗ |
Benjamin Cole | ✓ | ✗ | ✗ | ✗ | ✗ | ✗ |
Clara Finch | ✗ | ✗ | ✗ | ✓ | ✗ | ✗ |
Daniel Reed | ✗ | ✗ | ✗ | ✗ | ✗ | ✓ |
Evelyn Price | ✗ | ✓ | ✗ | ✗ | ✗ | ✗ |
Felix Grant | ✗ | ✗ | ✓ | ✗ | ✗ | ✗ |
The Answer
Felix Grant was in the Ballroom. Arthur Blackwell was discovered there at 11:45 PM, making Felix the prime suspect in this case. But there's one final question for the reader: Was Felix actually the killer — or was someone clever enough to frame him? That question can become the setup for the next case in the Death at the Grand Hotel series.
Book Layout Suggestion
For a finished puzzle book, I would spread this case across several pages:
Page 1: Case introduction + suspects
Page 2: Grand Hotel room descriptions
Page 3: Clues 1–5
Page 4: Clues 6–10
Page 5: Blank deduction grid
Page 6: Hint 1–2
Page 7: Hint 3–5
Page 8: Complete solution grid
Page 9: Step-by-step solution walkthrough
Page 10: Final case verdict + teaser for the next mystery
This structure keeps the actual answer separated from the puzzle-solving experience and gives readers a clear progression from case → clues → deduction → hints → solution.
My First Results
Over my first testing period, the catalog generated approximately:
10 books published
187 copies sold
Around $640 in total royalties
Several books continuing to generate occasional sales without me actively advertising them
12 Mystery Puzzle Books
|
Your results will depend heavily on your niche, keywords, covers, pricing, competition, and how many quality books you publish. For me, the important thing was the concept could actually turn into a repeatable publishing workflow.
At $19, I felt the purchase was worth it for the time it saved me and, more importantly, for giving me a product concept I could actually build a catalog around. But I wouldn't tell someone to buy Shigai Royalty because they expect an automatic income stream.
That's not how I used it. The software gave me the production capability. I still had to research keywords, create covers, choose titles, write listings, publish the books, and figure out which themes people actually wanted.
That's an important distinction. The tool can help you make the product. It can't make customers buy it. For me, though, that's exactly why I found the $19 purchase interesting. I wasn't paying for a magic button. I was paying for a specialized tool that removed one of the most tedious parts of creating logic-puzzle books.
If you're already interested in KDP or printable products and you're tired of competing in the same overcrowded puzzle niches, Shigai Royalty is one of the more interesting tools I'd consider testing. Just start small. Build a few quality books, see what gets traction, and then expand around the winners.
