RTPTrack launched with 5,655 slot pages. Every one shows the theoretical RTP, provider, volatility, and max win. But only 28 of those pages carry verified deployed RTP data — the actual per-casino deployment figures that the site exists to provide. That is 0.5% coverage.
Why so few
Verified deployment data requires one of three things. First, the operator publishes per-game RTP data (rare — Videoslots does, most don't). Second, provider documentation confirms the available tiers AND operator disclosures or community data identify which tier is deployed. Third, manual verification through authenticated casino sessions (time-intensive, not yet scaled).
We prioritised the 28 most-played titles first — Book of Dead, Gates of Olympus, Sweet Bonanza, Starburst, and the reference games that demonstrate the deployment problem most clearly. The Book of Dead deployment map (96.21% at Bet365, 87.25% at Aspire Global) has been cited across iGaming press. But 28 is not enough.
What we are doing about it
Expanding verification to 100 titles by Q3 2026. Prioritising titles from providers with the widest tier spreads (Play'n GO, Red Tiger). Building automated verification tools to check operator-published RTP pages. And being honest about coverage limitations on every page where data is pending. The provider tier guide shows the worst-case spread for each provider — use it while we expand.
What this means for you as a reader
On the 28 verified titles, trust the deployment data. On the remaining 5,627, treat the theoretical RTP as a maximum and assume your casino may deploy lower. The provider tier guide shows the worst-case spread for each provider. Use it to estimate your risk. The guide on how casinos change RTP covers the operator-side mechanics so you understand exactly what you are estimating.
Why we are publishing this
This page exists because transparency is not just our editorial standard — it is our product. If we hide our coverage limitations, we are no better than the casinos hiding their deployment tiers. How RTPTrack works and our about page cover the methodology in full. The honest answer to "do you have verified data on every slot?" is no — and the honest answer to "when will you?" is target 100 by Q3 2026, with the long tail handled through provider-tier estimation rather than per-title verification.

Can Casinos Change Slot RTP? Yes — and Here's Exactly How
UK casinos choose which RTP tier to deploy on every variable slot. The game looks identical. The maths change. Marcus Chen explains exactly how it works, with named providers, real numbers, and what UK players can actually do about it.
Every Fixed-RTP Slot Available in the UK: The Complete 2026 List
Fixed-RTP slots cannot be tier-reduced by operators. The published figure is the deployed figure at every UK casino that carries them. Sofia Lindgren catalogues the complete list by provider — what is fixed, what is not, and what to play in 2026 if you want maths consistency.
