The best known system tool for ensuring that a casino offers fair games is eCogra; however, there are other providers that also offer these kinds of systems. You want to make sure that the casino is using a certified third-party control system to ensure that the games of chance you’re playing are actually based on chance and not on other types of metrics. Rigged games are ones that have been set up to pay out less than they claim to or ones that give some players a greater chance of winning than others.
The eCogra logo can often be found in the footer of the casino’s website, but not all casinos choose to display it. If you can’t see this logo, go to the FAQs and see if you can find information about random number generators. If there are no FAQs on the site, check out their terms and conditions or contact the casino’s support and ask how they ensure their games are safe.
