From my experience, it’s a mix. Some review sites do dig deeper and test games over many sessions to check RTP accuracy, but often they rely on the numbers provided by the casino or software provider. I once followed a review that seemed solid, yet when I played, the actual returns were slightly lower than expected. That taught me to always double-check and consider multiple reviews. Resources like casino verification KYC guide also helped me understand which platforms are properly audited and trustworthy, making it easier to know whether the RTP claims are realistic. It’s all about being cautious and comparing data before trusting a single source.
