In a nutshell, testing companies ensure RNG engines are working as they should and that RTP percentages are accurate and up to date.
By conducting extensive and elaborate tests, these companies verify that game results in a particular game are, in fact, completely random. They will also monitor an incredibly vast amount of spins or hands to verify that the RTP percentages given by the game developer or casino are accurate. They will then publish these figures in regular reports for the sake of transparency and customers’ peace of mind. You usually access these reports by clicking on the company’s logo, which you will typically find in the casino’s footer.
Apart from these essential tests, many testing companies offer additional services. It’s not uncommon for these companies to provide consultancy and management services which help operators overcome the many challenges associated with multijurisdictional operations and compliance.
There may be varying conditions from one jurisdiction to another, and it is important for a casino to stay compliant in all jurisdictions in which it operates. For instance, some jurisdictions, such as the UK, have incredibly stringent rules when it comes to Responsible Gambling practices and marketing. If a casino fails to comply with these rules, it might receive hefty fines, or at worst, have its license revoked.
