To Lottostar or not to Lottostar... The answer has become simple

How can Lottostar have a game that might, might give once a week, and then very poorly. Are there no RTP policies? Won a small amount, but after that, absolutely nothing, and I have played the same game everyday for 2 weeks. How greedy do they want to be. I know it is gambling, but THEY know they have some of the worst payouts online. I am not talking about the occasional headline that ONE guy won R3 million, I am talking about fair play!
