Sometimes it seems like online casinos could pretty much do whatever they wanted and get away with it, especially when it comes to fixing their game payout percentages. Who is to say that a particular slot really has an RTP of 96% and that it hasn’t been tampered with? This is where auditors come into play. Auditors are independent agencies in charge of checking casino games for fairness and making sure the numbers they advertise are in line with the actual situation. There isn’t a huge number of these auditors, but those that do exist, such as eCOGRA, iTech labs, and Gaming Laboratories International (GLI), enjoy a great reputation in the industry.
