UK Gambling Commission (UKGC): The UK Gambling Commission is responsible for regulating all gambling performed in Great Britain, as well as supervising the country’s gaming laws, across all online casinos; iGaming websites licensed by the UK Gambling Commission must adhere to certain rules to ensure fair play.
Malta Gaming Authority (MGA): The MGA is responsible for regulating all gambling in the European State of Malta and it is one of the most sought licenses in the industry.
Curacao eGaming: Curacao is one of the longest established online gambling licence providers in the world. The Dutch Caribbean island has been issuing licences to the gambling industry since 1996 and continues to do so today as Curacao eGaming.
The Gibraltar Gambling Commission (GGC): Gibraltar has been offering highly regulated gambling licences to online casinos and sportsbooks since 1998 and is now a world leader in gambling regulation.

Live Chat: A communication tool connecting you to a casino’s customer-support agents instantly, for a text-based interaction; you’ll find a small live chat icon in different parts of a casino’s pages, such as the header or bottom-right corner. Agents may be available during a set period of the day only or 24/7, and live chat is compatible with mobile casinos too.
Email: As live chat becomes more commonplace, email support is less sought-after. However, most online casinos offer email assistance through a contact form or an address; response times vary, but usually fall within 24 or 48 hours. We have occasionally seen some casino brands that fail to respond completely. Some casinos offer multiple addresses to help you find the specific type of assistance you need (technical, registration etc.).
Phone: Phone-based support is less common now than it may have been, given the rise of live chat and the expense of calling a helpline. However, telephone support is ideal if you prefer to actually speak to an agent or if you’re unable to type. Some online casinos accept phone calls 24/7 or for several hours each day.
Free Phone Number: In rare cases, online casinos offer free helplines for UK-based customers. This is a fantastic option that reduces the stress of heavy charges and might be faster than waiting for an email response.
Call Back Function: Some online casinos will offer to pay for the cost of your support by calling you back, once you supply your number. This means, of course, that the company behind the casino may use this for marketing purposes, so be sure you trust the brand first.
Opening Hours: Live chat and phone support are available 24 hours a day, seven days a week in some cases, though it can be difficult for online casinos to operate a 24/7 telephone service. Most of the time, support is available between 08:00 CET and midnight throughout the week, though this may change at weekends.
