It started with sport betting, and I think PS does not offer sport betting. Hungarian government now fighting against the foreign sport betting sites (bet365 has been already eliminated). Orban's friendship wants the hungarians to loose their money at the local bookies: the one that is the national bookie and the other one that just been recently estabilished by one Orban's friends. Because the government manipulate the market, these local sites are not the offering the best conditions considering the odds, available matches, bonus, etc.
I am glad that Unibet still find the way to operate in the country and does not give up the fight and I hope that one day we will have a free internet where all the bookies available without any VPN.
