⚡ Quick Verdict
Sansuu Royalty is a cloud-based math worksheet generator for Amazon KDP that automatically creates 20 categories of math worksheets with verified answer keys, exports in 11 KDP trim sizes, and includes a built-in cover studio — all for $37 one-time. The product fills a real gap: auto-generated answer keys solve the #1 friction point in educational workbook publishing. The niche is less saturated than coloring books and journals. Ike Paz and Luke Bowes have a solid delivery track record. Critical caveat most reviews miss: there is NO refund policy — all sales are final. Buy with that clearly in mind.
What Is Sansuu Royalty?
Sansuu Royalty is a $37 one-time cloud-based math worksheet and workbook generator by Ike Paz and Luke Bowes of Royalty Prints on WarriorPlus that automatically creates math worksheets across 20 categories with verified answer keys, exports print-ready PDFs in 11 Amazon KDP trim sizes, and includes a built-in AI-powered book cover studio — designed for self-publishers who want to build passive KDP royalty income in the educational workbook niche without math, design, or formatting skills.
“Sansuu” (算数) is the Japanese word for elementary arithmetic — part of the team’s consistent Japanese naming convention: Moji (文字 = letters) for their literacy OTO, Rika (理科 = science) for their science OTO, Kumo (雲 = cloud) for their activity tool.
Ike Paz and Luke Bowes have been running KDP-focused WarriorPlus launches since 2023 — Kawaii Town Prints, Kumo Amazo, Ohanashi AI Gen, and Manaka Royalty. Each delivered functional software as described. Sansuu Royalty is their pivot into educational worksheets, which they argue is more defensible than coloring or journaling because math accuracy and answer keys create a barrier most would-be publishers don’t overcome.
The 20 Math Categories Covered
Why the Math Workbook Niche Is Worth Your Attention
The educational workbook niche on Amazon KDP remains one of the least saturated corners of self-publishing in 2026. Adult coloring books and blank journals became genuinely crowded after 2022. Math workbooks haven’t — because producing them accurately is harder. The answer-key problem creates a real barrier. Most would-be publishers start, realize they need to calculate hundreds of equations manually, and stop. Sansuu Royalty removes that barrier entirely.

Real-World Testing — 30 Days of Evaluation
We evaluated Sansuu Royalty across three US-based KDP publisher profiles.
vs. Book Bolt (Primary Competitor)
Book Bolt ($9.99–$19.99/month) covers the full KDP spectrum — puzzles, journals, coloring books, notebooks — with built-in keyword research. Its gap: no dedicated math worksheet generator with auto-calculated answer keys. Sansuu Royalty wins on educational-niche depth and one-time pricing. Book Bolt wins on breadth across all KDP formats. For a publisher specifically targeting math workbooks, Sansuu Royalty does more of the specialized work at a lower lifetime cost ($37 once vs. $120–$240/year).
vs. Manual Creation in Google Docs / Canva
Creating a 30-page math workbook manually — typing equations, calculating answers, formatting to KDP specs, building a cover — takes 8–15 hours for a non-designer. Sansuu Royalty reduces this to 30–45 minutes per book. At the US average knowledge-worker rate of $47/hour, the time saving on a single book is worth $375–$700 against a $37 one-time tool cost.
Pros & Cons: The Honest Breakdown

✓ Multi-platform commercial rights: KDP, Etsy, TPT, Zazzle, Lulu
✓ $37 one-time vs. $120–$240/year for Book Bolt subscription
✓ Ike Paz & Luke Bowes have 5+ delivered KDP tools — low vendor risk
✓ Educational niche less saturated than coloring/journaling
✗ No custom problem parameters beyond Easy/Medium/Hard
✗ KDP income requires catalog volume — 1–2 books rarely generate meaningful royalties
✗ Full funnel cost ($37+$47+$77+$197) = $358 total
✗ Income case study ($4,193 from 3 books) is real but not typical
✗ Established publishers have catalog and review-count advantages

Is Sansuu Royalty a Scam?
No. Sansuu Royalty is a legitimate product from Royalty Prints, a WarriorPlus vendor with a verified delivery track record across five prior KDP tools (Kawaii Town Prints, Kumo Amazo, Ohanashi AI Gen, Manaka Royalty, and the original Royalty Prints). The software works as described. Independent reviews from reviewaiapps.com and other non-affiliate sources confirm the core functionality delivers.
The legitimate concern: the no-refund policy creates a one-way financial commitment. The income case studies are real but represent strong outcomes, not median results. Set realistic catalog-building expectations and you’ll find the product overdelivers at its price point.
Who Should (and Shouldn’t) Buy This?
Buy It If You’re:
Don’t Buy If You’re:
Expecting significant income from 1–3 books. Uncomfortable with the no-refund policy. Looking for Book Bolt-level breadth across all KDP formats. Needing highly customized problem parameters beyond the Easy/Medium/Hard options.
Frequently Asked Questions
Is Sansuu Royalty a scam or legit?
Legit. Royalty Prints has a verified WarriorPlus track record across 5+ prior KDP tools. The software works as described. Our Sansuu Royalty review rating is 8.3/10. The critical caveat is the no-refund policy — all sales are final.
Is there really no refund? Some reviews say 30-day guarantee.
The official sales page FAQ explicitly states “all sales are final.” Multiple affiliate review sites incorrectly claim a 30-day guarantee — this appears to be a template error. Verify the current refund policy on the live sales page before purchasing. Do not rely on third-party review sites for this information.
Do I need to buy OTOs to publish a complete math workbook?
No. The $37 FE includes everything needed: worksheet generator, answer keys, cover studio, KDP formatting, and commercial license. OTO 1 adds Amazon Ads training. OTO 2 adds early-literacy tools. OTO 3 adds science worksheets. None are required for math workbook publishing.
Can I sell on Etsy and KDP simultaneously?
Yes — the commercial license covers KDP, Etsy, Teachers Pay Teachers, Zazzle, Creative Market, Lulu, Blurb, and PublishDrive. The same PDF works as a KDP paperback interior and an Etsy instant-download printable.
What does “Sansuu” mean?
Sansuu (算数) is the Japanese word for elementary arithmetic/math. The team uses Japanese vocabulary across their product line: Moji (文字 = letters), Rika (理科 = science), Kumo (雲 = cloud), Ohanashi (お話 = story). It reflects the niche each tool covers.
How much can I realistically earn from math workbooks?
A single math workbook at $7.99 earns approximately $2.80 in KDP royalties per sale. At 20 sales/month per title and 10 titles published, that’s ~$560/month. Median first-year KDP publishers earn under $100/month total — the income compounds with catalog volume over 12–24 months of consistent publishing.
Final Verdict: Is Sansuu Royalty Worth $37?
Sansuu Royalty earns its 8.3/10 by solving a real problem at a fair price in a genuinely less-saturated niche. The auto-generated answer key feature removes the primary friction point in educational workbook publishing. The tool delivers functional software from a vendor with a track record. $37 one-time compares favorably against $120–$240/year subscription alternatives that don’t offer the same math-specific depth.
The deduction comes from the no-refund policy — a higher buyer risk than most WarriorPlus tools — and the income case studies that present above-average outcomes as representative. Publishers who go in understanding this as a catalog-building business tool rather than a passive income shortcut will find it delivers well above its price point.
Buy the $37 FE, publish your first 3 books, and evaluate whether the OTOs accelerate what’s already working.
