The Product
Jikan Nazo (Ike Paz / Luke Bowes / Marina) is a find-the-number elimination mystery engine. You work with a register of numbers and clues that eliminate possibilities until exactly one solution remains — a whodunit you can verify, not a pile of disconnected grids.
Whole books can be generated in one run (large registers supported on the front end), with difficulty bands from Gentle through Standard to Fiendish, KDP trim options including large print, answer keys with per-clue elimination witnesses, front and back matter, and coded answers. Export paths cover unlimited PNG plus a monthly PDF allowance, plus custom imports and seeded generation for repeatable series work.
The angle is deliberate: verified one-solution number mysteries for publishers who are tired of flooding the same word-search categories.
Fit Check
Good fit if: you want logic / number / whodunit puzzle books with a clear “one correct solution” promise, you’re publishing for KDP or printables, and you’d rather ship interiors than invent elimination logic by hand. Also a fit if you like series publishing — seeded runs and difficulty bands make Gentle → Fiendish ladders practical.
Skip if: you expected finished covers, listings, and marketing done for you, or you want a prose fiction bot. This is an interior engine. You still design, list, and sell. And if you were hoping for overnight money from a dashboard screenshot — that isn’t what this is.

Difficulty chips:
Optional funnel items may appear at checkout — confirm on the official sales page. Nothing beyond the front end is required to start. Sales are final as stated on the FE.
Market Angle
Puzzle buyers already browse Amazon for mysteries and logic books. A find-the-number elimination format gives them a reason to finish — they’re not circling random words; they’re crossing out possibilities until one answer stands. That “verified one solution” promise is easier to explain on a cover than another generic activity pack.
Because interiors can be seeded and difficulty-banded, you can plan a short series ladder instead of reinventing the wheel every time. Covers, titles, and keywords still decide whether shoppers click — the engine just removes the hardest part of building fair elimination logic.
Straight Talk
If you want a structured way into number-mystery and elimination whodunit books — verified single solutions, difficulty bands, answer witnesses, KDP trims including large print — Jikan Nazo is worth a look when it opens. It is aimed at publishers who are done dumping undifferentiated word-search interiors into the same crowded shelf.
It is still a tool, not a business in a box. It does not design your covers, write your listings, or run your marketing. There is no overnight money here, and member dashboards you may see elsewhere are not typical results. Sales are final as stated on the vendor front end, so read the checkout terms before you buy.
At $19 on WarriorPlus for a short launch window (opens Wednesday 23 September 2026 at 08:00 EDT, closes Saturday 26 September), it is a modest test if elimination number mysteries are actually on your publishing list. Skip it if you need someone else to hand you finished, marketed books.
Front-end is $19 on WarriorPlus. Opens Wednesday 23 September 2026 at 08:00 EDT · closes Saturday 26 September 23:59.
