Online Casino Auditors

Online casino auditors

Every reasonable fan of online gambling prefers to play at an honest casino and safely trust his money. But how to distinguish a decent website from a fraudulent one? The logo of the gambling regulator in the footer and the attached license copy is not enough to be sure of its reliability. 

An important advantage of an online casino, which is trying to enhance trust, is cooperation with independent audit organizations. There are several well-known companies in the gambling business involved in checking websites that provide services of this kind.

How to make sure the casino has been audited?

Usually, gambling sites cooperating with such organizations post auditors' logos in the footer. They feature links to executed test reports, certificates, or official sites with detailed information. 

Some fraudulent casinos display fake logos. Usually, they have no links.

If you are in doubt whether the casino has been audited, please contact the support team for clarification. Contact details can be found in the reviews of gambling auditors.

Can I complain about the casino to the auditor?

Resolving disputes between gambling operators and customers is a standard service provided by many independent audit organizations.

If a casino, bookmaker, or poker room cooperates with a company engaged in such activities, you can send a request to the organization. As a rule, this can be done on its official website, using a special questionnaire or writing to the support service.

But first, make sure that your claims are justified, and try to settle the problem with the casino representatives. It is often possible to reach a compromise without intermediaries.
