If you can’t find a matching record, don’t take the casino’s word for it. To do so, take the information from the site’s footer (company name and address and licence number) and check it against the regulator’s public licence register. However, even if the badge works and the licence appears to be valid, you should take additional steps to ensure that the casino company behind the platform is genuinely who it claims to be. If the badge isn’t clickable, it is a legitimate cause for concern as it might mean that the casino hasn’t renewed its permit. Learning information about a new casino first-hand is key to making an informed choice and picking a casino site that works for you.
