  • Licence Check: Visit the UK GC website and confirm the casino’s registration number.
  • SSL Encryption: Ensure the site URL shows https with a valid certificate to protect personal data.
  • GDPR Compatibility: Look for a privacy policy that outlines data usage and user rights.
  • Fair Play Enforcement: Verify that random number generators (RNGs) are certified by independent bodies such as H+P, eCOGRA, or iTech Labs.
  • Third‑Party Audits: Seek evidence of regular audits, including player‑balance reports and volatility assessments.

Before depositing, check that the casino displays a recent audit report and a licence screenshot. These indicators confirm that your funds and personal data are protected under industry‑wide safety protocols.
