You can refer to company’s list of licenses and authorites that regulate Microgaming casinos. As I mentioned before Microgaming casinos are lincesed by the UK Gambling Commission (lincense #39073), MGA (MGA/B2B/139/2007, MGA/B2B/124/2006 and MGA/B2B/235/2013), eCogra, and others. Also pay attention to the fact that Microgaming cares about its clients through supporting them by informing and helping with gambling addiction. These organisations are helping: gamcare.org.uk and begambleaware.org.
