True, that explains a lot, but it is still unclear why users from countries that are blacklisted by game providers (Indonesia for example) can not play with fiat on other games..(?) I think it should be explained more clearly so that no one has any doubts.
Are you new to gambling? It's common for certain 3rd party slots providers to block certain countries. It can be because of the license, or the game deemed not suitable for the country. None of these hosting casinos give detail explanation of it. For example, NetEnt on Stake and Duelbits also banned users from Indonesia. Perhaps it's because SoftSwiss license.
If you like NetEnt games, you can play at non-SoftSwiss powered casino such as BK8. Or use VPN if it not violates ToS.
