Shigai Royalty – Can You Publish Murder Mystery Puzzle Books Without Writing a Single Clue?

If you’ve published low-content books on Amazon, you know the feeling. Word search book number 4,000. Sudoku book number 9,000. Your new title lands on page 50 of the search results next to thousands of lookalikes, and it never sells. The publishers who do well are usually the ones who reach a hungry niche before the shelf fills up. Shigai Royalty is built around one of those niches: story-driven murder mystery logic puzzles.

I bought Shigai Royalty and used it to build a complete mystery puzzle book for KDP, plus a printable pack from the same files. Here’s how the engine works, the features that matter, the price, the upgrades, and what my first book has earned so far.

What Is Shigai Royalty? How Does It Work Step By Step?

Shigai Royalty is a cloud-based engine that builds complete Murdoku-style whodunit puzzle books. Each case has a mansion grid, a cast of suspects, true statements as clues and one room holding the victim. The solver places every suspect by pure deduction, and whoever ends up alone with the body is the culprit. The engine builds the puzzles, clues, hints and step-by-step solutions, verifies that every puzzle has exactly one solution, and lays everything out as a print-ready book for Amazon KDP or as printables for Etsy-style marketplaces.

Here’s how a whole puzzle book comes together in three steps:

➤ Step 1 — Create. Choose the difficulty (Easy to Dragon 🐉), the grid size (6×6 to 16×16), your cast and your rooms, then click generate. The engine builds and verifies the whole case: the puzzle, the clues, the hints and the solution walkthrough.

➤ Step 2 — Export. The page designer handles margins, fonts, KDP trim sizes (including full bleed) and legends. Bulk mode fills a whole book in one pass, so there’s no formatting or resizing to fight with.

➤ Step 3 — Collect. Upload the book to Amazon KDP as a paperback, where Amazon prints, ships and pays you, or sell the same files as an instant-download printable. One build gives you two income streams.

About The Creator

Shigai Royalty is created by Ike Paz and Luke Bowes, the co-founders of Royalty Prints. Ike is a book and printable seller and a serial WarriorPlus vendor, and Luke is the developer and engineer behind the puzzle engine. Together they’ve built a strong reputation among KDP publishers for practical software that simplifies self-publishing, and the Shigai Royalty launch was featured as WarriorPlus’s Deal Of The Day.

You may already know their earlier tools, including Kuro Nazo, Techo Royalty, Sansuu Royalty, Manaka Royalty, Nurie Creator, Kawaii Town Prints and Brain Game Prints. What I appreciate most is that Ike and Luke are personally in the member group every day, and members often mention their support as the best part of buying from them. That kind of involvement gives me real confidence in Shigai Royalty.

Shigai Royalty Review – Key Features

✅ Verified Deduction Engine: The engine builds each case mathematically and checks that every board has exactly one solution, reachable by pure logic with no guessing. That’s the hard part of this puzzle type, and it’s what keeps buyers happy and protects your reviews. You get five solver-calibrated difficulties and grids from 6×6 up to 16×16, including non-square layouts.

✅ Custom Casts And Rooms: Name your suspects, set their genders, pick preset portraits or upload your own photos, and rename the rooms. This turns one engine into endless niches: office mysteries, cruise-ship capers, haunted hotels or personalized gift books starring friends and family.

✅ Murder Mystery And The Heist Modes: Publish classic “Find the Killer” books, or switch to The Heist mode for “Find the Thief” books with the same addictive logic and a family-friendly angle. Two modes give you two shelves to fill.

✅ Hints Ladder And Step-By-Step Walkthroughs: Every solution page gets a hints ladder and a step-by-step deduction walkthrough. Buyers never get stuck, so they finish the book, leave a review and come back for the next volume.

✅ How-To-Solve Tutorial Page: One click adds a worked-example spread to your book: a real, verified 4×4 mini-case solved step by step. It’s a simple way to turn first-time solvers into fans.

✅ Full KDP Page Designer With Bulk Mode: Control margins, fonts, trim sizes, difficulty badges and the CAN-OCCUPY/BLOCKED legends, and drag grids into place. Bulk mode lets you set the page count, queue the whole book and generate it in one pass.

✅ 8 Book Languages: Publish in English, Spanish, French, German, Italian, Portuguese, Dutch or Polish. The engine verifies every case in English, then re-renders each clue in your chosen language, so you can reach eight Amazon markets from one build.

✅ 2 Artwork Packs: Choose the classic Illustrated look or the clean Flat Avatar style for each book. Two visual identities let you give different series a distinct feel.

✅ Voice Control, Custom Characters And Swap The Furniture: The newest build lets you speak commands like “Make it a 9 by 9 grid” or “Six suspects, Victorian manor,” type in your own characters with roles, and swap any object in a room. After every change, the engine re-verifies that the puzzle still has exactly one answer.

✅ Print-Ready Exports And Commercial Rights: Export print-ready PDFs and unlimited high-resolution PNGs, sized for KDP trims and ready for printable marketplaces. You keep full commercial rights and 100% of your royalties.

Shigai Royalty Pricing & Funnel Summary

Shigai Royalty Front End ($17)

At checkout on WarriorPlus, Shigai Royalty showed a sale price of $21, and the coupon code SGDJDYRW took off another $4, so I paid $17 one-time. There are no recurring fees on this offer. The front end includes the verified deduction engine, all 5 difficulties and grid sizes, custom casts with photo upload, custom rooms, Murder Mystery and The Heist modes, hints and walkthroughs, the How-to-Solve tutorial, the full KDP page designer with bulk mode, 8 book languages, 2 artwork packs, voice control, custom characters, swappable furniture, print-ready PDF and unlimited PNG exports, full commercial rights and the five bonus tools.

Is it worth it? I’d compare it with the alternative: building verified logic mysteries by hand takes weeks per book, and a freelancer charges premium fees for puzzles you can’t even check. For $17, Shigai Royalty builds verified, print-ready books in minutes in a niche with far less competition than word searches or sudoku. It’s a natural fit for KDP publishers, printable sellers and anyone looking for a fresh low-content niche. One small thing worth knowing: the front end includes 100 PDF exports a month alongside unlimited PNGs, which was plenty for my first book and printable pack, and Shigai Royalty Pro makes PDF exports unlimited if you publish at volume.

Why Should You Choose Shigai Royalty?

My Personal Experience With Shigai Royalty

For my first book, I wanted a cozy, classic feel that would appeal to adult puzzle fans who also read Agatha Christie. I called it “The Blackthorn Manor Casebook”: a 120-page, 8.5×11 paperback with 40 murder mystery puzzles set in one Victorian manor, arranged as a difficulty ladder from Easy to Dragon.

Here’s how I structured “The Blackthorn Manor Casebook”:

• Front Matter — How To Solve: the one-click 4×4 tutorial spread, plus a short welcome from “the butler.”
• Part 1 — The Weekend Guests (Cases 1–10): Easy, 6×6 grids, five suspects, rooms like the Library, Conservatory and Wine Cellar.
• Part 2 — The Storm Night (Cases 11–20): Medium, 8×8 grids, six suspects and a locked Gallery.
• Part 3 — The Missing Will (Cases 21–30): Hard, 10×10 grids, seven suspects, with the Heist mode used for three “Find the Thief” cases.
• Part 4 — The Final Reckoning (Cases 31–40): Expert and Dragon, 12×12 to 14×14 grids with eight suspects.
• Back Matter: hints ladders, full step-by-step solutions and a QR code page linking to the next volume.

The custom cast made the book feel like a story. I named the suspects Lady Agatha Blackthorn, Colonel Hartley, the cook Mrs. Pennywhistle, Dr. Ashcombe, the gardener Tobias and the young heiress Clara. A typical clue from Case 14 read: “Colonel Hartley was not in a room with a window.” Another said: “Mrs. Pennywhistle was alone, and she was not in the Kitchen.” Watching the engine re-verify the case after I swapped a grand piano into the Music Room was the moment I trusted it completely.

Generating all 40 cases in bulk mode took about 15 minutes. Most of my time went into the cover, the keywords (with the KDP Keyword Finder bonus) and a careful proofread of the PDF, around three hours in all, which is normal for any paperback launch. I also exported 20 of the cases as PNGs and listed them as a “Murder Mystery Game Night” printable pack.

Over the five weeks since publishing, the paperback has sold 189 copies for approximately $561 in royalties, and the printable pack has added 40 sales worth $190. While those numbers aren’t life-changing, they came from one book in a quiet niche, and Volume 2, set on a cruise ship, is already in progress.
