UK Gambling Commission

The body has been actively licensing and regulating gambling platforms since 2007. We prefer sites that hold a UK Gambling Commission license since they adhere to strict guidelines to avoid lawsuits, fines, or even face the risk of being banned.


Malta Gaming Authority

Curacao eGaming
