Gambling Auditors: Ensuring Fairness and Transparency in the Gaming Industry

Online gambling has become increasingly popular over the years, with many people enjoying the convenience of being able to play their favorite games from the comfort of their own homes. However, with this rise in popularity comes a need for regulation and oversight to ensure that these online casinos are operating fairly and ethically.

On this page, we will provide you with information on the role of online gambling auditors, their importance in the industry, and the types of audits they perform. We'll also offer insights into what to look for in a reputable online gambling auditor and highlight some of the leading auditing firms in the industry. Whether you're an online gambling enthusiast or just interested in learning more about the industry, we hope this page provides you with valuable insights and information about the role of online gambling auditors.

Online Gambling Auditors

With thousands of online casinos, some less trustworthy than others, consumers must be protected against unfair practices. The following bodies are independent organizations that audit online casinos.

Online gambling operators are responsible for running thousands of sites worldwide. But unfortunately, only some operators uphold the same elite standards of the most trusted brands. This has led to a rise in the need for gambling auditors to help prove the legitimacy of the fairly operated iGaming brands.

Quite simply, auditing is a process of testing that can align with the remote gaming licenses handed out from gambling jurisdictions dotted across the globe. In addition, auditing a gambling site can provide evidence to a licensor that the brand runs with software that can be trusted.

Independent Testing

Ideally, a trusted gambling operator shall employ an independently run auditor to undertake to test. This is expected to occur frequently throughout the year. Monthly is the best scenario, but some trusted sites might undergo testing every quarter. In any case, it is reassuring for players to know that this happens.

Now, the auditing constitutes the testing of the gaming software and random number generator (RNG) algorithms used to simulate the outcomes of games. For instance, the auditor could seek to ensure that video slots align with the long-term return to player (RTP) percentages that the games' developers have programmed.

Keeping Players Safe

Some online casino sites ran pirated software from well-known and reputable providers in the past. However, the culprits have been caught only through licensing and auditing. The threat is unlikely to go away entirely, but auditing can help to keep players safe.

Using this page, you can check the bottom of your casino's homepage to see if there are auditor names such as eCOGRA, iTech Labs, or another. If you have any doubts, contact customer support and ask for the name of the auditor that tests the site.


The non-profit, independent standards authority of the online gaming industry, e-Commerce, and Online Gaming Regulation and Assurance, better known as eCOGRA, provides important player protections to consumers.

These result from Independent Directors' decisions concerning what casino software is rewarded the Safe and fair Seal.

eCOGRA specifically oversees fair gaming, player protection, and responsible operator conduct. It examines and tests online gambling sites' prompt payments, safe storage of information practices, random games, honest advertising, and responsible behavior by the operator.

The standards authority was founded by Microgaming Software Systems Ltd. and Virtual Holdings Ltd., which together account for a large part of casino-style gaming on the Internet. However, it is up to independent directors to decide which software developers are admitted as eCOGRA members and which operators qualify for the eCOGRA Seal.

Finally, if a player encounters problems while gambling at an approved site, eCOGRA provides a dispute mediation service and a fair gaming advocate.

The most important product of eCOGRA - the one that players encounter in their gambling adventures - is the Seal of Approval, awarded to those casinos which have achieved compliance with eCOGRA's high standards and demonstrated that:

  • Games are fair
  • The casino operates honestly and behaves responsibly
  • Monetary deposits are safe, and winning bets are paid promptly.
