They have the list but it is not located under the terms page, you can find it on the
Accounts, Payouts and Bonuses page. Lemme make it easy for you by quoting the list of the restricted countries, check it out:
1.1.2. You are not allowed to register on the Website and use our services if you are a resident of Curacao, France, Iran, Iraq, Netherlands, North Korea, Singapore, Spain, St. Maarten, Statia, USA or the USA dependencies, Ukraine, United Kingdom, Turkey, Aruba, Bonaire, Saba, St Eustatius. We reserve the right to refuse customers from any other countries over and above the aforementioned jurisdictions at our own discretion.
Just small number of restricted countries unlike other casinos where the list can be much longer than above list.
The list is short now but it can be updated and there are possibly extra restrictions from their partners, game providers. It happens with many online gambling sites, like their home-grown restrictions plus game provider restrictions. It can make users confusing a little bit when they are allowed by the platform but later when playing some games, they see restriction notifications.
