Most slot reviews score poorly on E-E-A-T because they quote RTP without source citations. Our widget ships a copy-paste JSON-LD snippet — paste it in your page <head> alongside the iframe. Google reads it as Dataset + Product structured data attached to your URL.
Optional <Affiliate URL> + <Label> turns the widget into a CTA for your casino partner. No revenue share — we don't take a cut. Click goes straight to your tracking link with rel="sponsored nofollow" (correct per Google guidelines).
Weekly Monday cron re-scrapes all 15 providers. RTP changes propagate to every embed automatically — you don't refresh anything. Each record carries source_url + sha256 snapshot hash, so the citation is auditable.
Each widget shows a Verified pill + last-refresh date + tracked-since timestamp. Readers see at a glance that the data is current. Stable for the last N weeks = signal of provider reliability.
Free tier: small "data: toolsgambling.com" link in the widget footer (one inbound link to us per embed). Pro tier (manual issuance — DM): white-label, no attribution, custom domain. No signup, no Stripe, no friction for the free tier.
Every entry is a real slot from one of 15 production providers (Pragmatic Play, NetEnt, Play’n GO, Yggdrasil, BGaming and 10 others). For each slot we store stated RTP, native RTP variants when the provider publishes them, volatility, max win, release year, and source URL. 707 slots have multiple RTP variants published by the provider — that’s the data point you won’t find anywhere else.
We scrape each provider’s public website, store a content snapshot (sha256 hash) for every record, and refresh weekly via cron. No regulator data — regulators don’t publish per-slot RTP. We track what providers themselves publish, which is the same source any other site has access to. See methodology for the full provenance chain.

Provider-published RTP sits across 15+ provider websites, each with its own format. Casino help pages show a different RTP again — the value the operator licensed for that specific install. Affiliate sites quote numbers without source citations. Journalists writing about gambling math have no canonical place to verify a claim.
It's the value the provider declares to regulators and casinos. Different operators may license different variants (e.g. 96.5% / 94.5% / 92.0% for the same game), but the provider's published value is the audited reference. Tracking it cleanly, with snapshot evidence, is what makes downstream comparison possible.
One database. One source per record. One canonical URL for citation. Free to embed with attribution, free to query via API, weekly-refreshed via cron — no manual edit-then-deploy loop.
Every record carries a source_url + snapshot_id (sha256 hash of the scraped HTML at fetch time) + last_verified. 270 MB of raw HTML evidence stored. Verifiable, not vibes.
707 slots with 2–7 RTP variants the provider explicitly publishes (Play'n GO publishes 5 variants per slot, Yggdrasil publishes ranges). Most registries flatten this to a single number — we don't.
Mondays 06:00 UTC, all 15 providers re-scraped. Six trigger criteria detect material change (≥0.5% RTP shift, any new variant, ≥25 new slots, coverage status changes, etc.). Public changelog auto-fills. /rtp/changelog
All data licensed CC-BY 4.0. Reusable for journalism, research, commercial integration — with attribution. Schema.org Dataset markup makes it indexable in Google Dataset Search.
Free for affiliate sites, blogs, casino reviews — three sizes, three themes, custom accent color. Iframe embed, no setup. Each embed gets a dofollow link back to the registry. how to embed
Public JSON API, 1,000 requests / 24h per IP, no signup required. Pro tier (early access via email) for higher quota. API docs
Verified facts, ready to drop into your own writing. Or copy a pre-written template if you're in a hurry.
RTP is provider-stated and represents long-run expected return, not single-session result. Casinos may install regional or operator-specific variants; check the slot's info page in your casino client for the live value.
