I was blocked without any explanation. Support simply ignores my request to withdraw money.
I suspect that the block is related to the fact that I'm from Russia. However, Russia is not listed among the countries whose players are prohibited from playing on the site.
Jackbit terms aren't clear about the list of restricted countries. They haven't mentioned any restricted countries name in their terms. Jackbit team have left the responsibility on the players to check it out whether gambling is legal in their country or not. This is one kind of shabby practice by not making the terms clear. They had forfeited the winnings of a Russian player in the past by returning his deposits only. Looks like the user had a similar problem like you. Here is the response from them in that case.
Users from the Russia aren't allowed play real money games
Your funds will be refunded without problem. Drop me your username and I will forward to Jackbit team as well
