But how can players rely on the RNG? Independent testing labs audit it. Agencies like eCOGRA and iTech Labs run the software through its paces, analyzing millions of simulated plays to validate the results are random and statistically sound. You’ll usually find certification badges from these auditors on the casino’s website. These seals are public proof that the games are fair and function according to their advertised payout rates. This external check gives players objective confidence that the games aren’t fixed.
