Tantei Box transforms ordinary word search puzzles into addictive, print-ready murder mystery books that stand out immediately on Amazon KDP, Etsy, and Gumroad.
Instead of spending weekends hiding words and checking logic by hand, this automated engine builds complete elimination-style detective books—complete with verified grids, deductive clues, and matching answer keys—in just a few clicks so you can publish your next mystery puzzle book in about an hour.
"Trying to make an elimination word search by hand used to take an entire weekend just to verify that the missing suspect didn't accidentally appear in the grid. Tantei Box automates the logic check and builds the answer keys in seconds, cutting book production down to about an hour."
"Readers love board-game-style whodunits where they deduce the victim, killer, room, and weapon. Having Tantei Box generate all four categories, write the final clues, and export directly in 8.5 × 11 KDP trim sizes makes launching a multi-volume detective series effortless."
"Most puzzle generators lock you into rigid PDF templates. Exporting editable PowerPoint files and 300 DPI PNGs from Tantei Box lets me customize fonts, add custom cover themes, and sell printable mystery packs on Etsy alongside my KDP paperbacks."
Tantei Box is a browser-based puzzle book creation platform developed by Royalty Prints, specifically engineered to generate interactive mystery word search books. Rather than producing standard word-find grids where every listed term appears in the puzzle, the software uses an elimination mechanic: each puzzle includes a list of suspects, locations, or clues where every entry except one is hidden inside the grid. Once a solver circles all the hidden words, the single leftover entry becomes a vital clue that feeds into an overarching case file or back-of-book deduction challenge.
To serve different reader demographics and publishing styles, the core platform packages four distinct puzzle structures into one dashboard: Find the ONE (bulk generation of 10 to 300 connected puzzles with automated deductive clues), Single Elimination (facing-page layouts pairing clues and name banks with adjacent grids), One Grid, Four Answers (a single board-game-style grid revealing victim, killer, location, and weapon), and Four Grids, Four Answers (multi-grid case breakdowns). Publishers can populate these templates using built-in name databases or upload custom .txt word lists (English A–Z), while customizing grid dimensions (15×15 and larger), cell shapes, line weights, colors, and KDP-compatible trim sizes.
Beyond puzzle assembly, the engine includes automated logic verification to guarantee that omitted words never appear by accident and that every mystery resolves to a single, unambiguous solution—preventing the faulty-clue errors that often trigger negative buyer reviews. Once a book interior is finalized, creators can export flat or editable PDFs, scalable SVGs, editable PowerPoint (.pptx) files, high-resolution 300 DPI PNGs, and structured answer data in CSV, Excel, or JSON formats for commercial publication across print-on-demand marketplaces and digital storefronts.
Tantei Box is created by Ike Paz and Luke Bowes, the co-founders of Royalty Prints. Ike Paz is a practicing Amazon KDP and printable book publisher who handles the niche strategy, user workflow, and training side of the business. Luke Bowes is the software engineer responsible for building the cloud-based application architecture and export systems. Together, they have released a catalog of specialized self-publishing tools—including Manaka Royalty, Techo Royalty, Shigai Royalty, and Jikan Nazo—designed to speed up interior production for low-content and puzzle book creators.
For Tantei Box, Paz and Bowes partnered again with Marina Matic, the puzzle-engine architect behind Jikan Nazo. Matic developed the underlying constraint-verification algorithms that guarantee every elimination word search omits only the intended suspect and resolves to a single, unambiguous answer—preventing broken logic or duplicate solutions before a book is ever exported.
Because the development team combines active self-publishing experience with dedicated puzzle-logic engineering, Tantei Box is tailored directly to real KDP and Etsy production standards rather than generic template generation. Buyers also receive direct support and video training from the creators inside the members' area, backed by a team with an established track record of maintaining browser-based publishing software.
With Tantei Box, you can generate complete, print-ready mystery word search interiors tailored for Amazon KDP paperbacks, spiral-bound activity books, and downloadable printables. The core software produces four distinct puzzle layouts—Find the ONE (10 to 300 connected cases), Single Elimination facing-page spreads, One Grid, Four Answers (solving victim, killer, location, and weapon in one grid), and Four Grids, Four Answers—alongside auto-written deductive clue sheets, decode keys, and visual answer keys.
In terms of themes and niches, publishers can print cozy mansion murder mysteries, seasonal holiday whodunits, large-print detective editions for seniors, and simplified kids' detective club activity books (by toggling off math-based clues). Depending on which tier you use, printed pages can also incorporate numeric searches (dates, phone numbers, coordinates, license plates), zigzag snake paths, hexagonal grids, floor-plan alibis, card hands, and visual color or symbol runs—all exported in standard KDP trim sizes as flat or editable PDFs, SVGs, PowerPoint files, or 300 DPI PNGs.
One-Time Payment Structure:
Unlike subscription-based KDP design platforms that charge monthly fees, Tantei Box uses a single one-time payment model across its base software and optional upgrades, keeping ongoing overhead predictable for independent publishers.
Cross-Platform Browser Access:
Because the application runs entirely in the cloud, it works seamlessly on both Windows PCs and macOS computers without requiring heavy local software installations or manual updates.
Custom Vocabulary File Imports:
Beyond the built-in suspect and clue databases, publishers can upload their own plain-text (.txt) word lists to build hyper-targeted themes—such as historical mysteries, cozy holiday cases, or custom family party games.
Structured Data Exports (CSV, Excel, JSON):
Tantei Box exports complete puzzle and solution records in CSV, Excel, and JSON formats, making it easy to catalog answers, verify series continuity, or repurpose puzzle data for apps and digital workbooks.
Included Launch-Window KDP Utilities:
Buyers during the launch window receive five practical browser tools—PDF Page Mover, KDP Keyword Finder, Description Helper, QR Book Generator, and KDP Research Tool & Niche Revealer—to assist with keyword research, listing copy, and post-export page organization.
Direct Developer Support & Video Training:
Instead of outsourcing help tickets to third-party agents, the creators provide concise, step-by-step video tutorials and handle customer support directly inside the members' portal.
High Series & Repeat-Buyer Potential:
Because mystery puzzle books follow an episodic "case file" structure, readers who enjoy solving Volume 1 are naturally inclined to purchase subsequent volumes, supporting long-term catalog growth.
Strict No-Refund Policy:
All purchases are explicitly marked as final with no money-back guarantee, meaning buyers cannot test the software risk-free before committing.
Monthly Export Limit on the Base Tier:
The $19 front-end license caps exports at 100 PDF downloads per month; high-volume publishers who need unlimited PDF generation must purchase the $57 Pro upgrade.
English-Only Custom Word Imports:
Custom .txt file uploads currently support standard English A–Z characters only, limiting publishers who want to create mystery word searches in non-English alphabets or accented languages.
