RTPTrack tracks the actual deployed Return-to-Player setting on slots at UK-licensed casinos. The same game can run at different RTP tiers depending on which configuration each operator selects — we show you which figure is live where.

Is RTPTrack free to use?

Yes, completely free. You can search any slot, compare casinos, and read all our guides without paying anything. We earn revenue through affiliate partnerships when readers sign up at casinos through our links.

How often is the data updated?

Theoretical RTPs are verified against provider specifications. Casino-specific deployment is re-checked on an ongoing basis using a combination of provider tier data, operator disclosures, and independent verification. When we detect a tier change, we update the affected pages.

Does RTPTrack guarantee I will win?

No. RTP is a long-run statistical average across millions of spins. Higher RTP improves expected value, but it cannot predict any individual session. Slots remain random and the house always has a mathematical edge — RTPTrack reduces uncertainty about deployment, not about outcomes.

Which casinos does RTPTrack track?

We track deployment data across UKGC-licensed operators including Bet365, PlayOJO, LeoVegas, Casumo, Mr Green, 888 Casino, William Hill, Ladbrokes, Betsson, and many more. Coverage continues to expand as we verify additional operators.
