Nowadays, it's more common that casinos exist a while before their team figure out that they can get some good exposure at Bitcointalk. It can be from one of their team members or introduction from third party marketing people.
I know that nowadays it's more common for casinos to start a business outside of this forum but all I want to say is that I have never seen such a successful one as Metawin is. Primedice (maybe Stake too), Sportsbet, Livecasino, Bitsler, Crypto-games, FortuneJack, Rollbit, Duelbits, etc... they are the most popular crypto casinos, they all started from this forum, they have a huge bankroll, huge popularity, huge number of active players and good promotions. Then there is a Metawin that is almost on their level. I don't know any casino outside of this forum that is as popular as Metawin, that's why I feel curious.
As someone who enjoys highly volatile slots, I'm really liking the added volatility meter since it's a lot easier to discover new games that I might like.
Yes, that RTP and Volatility indicator is the best thing that can help you to decide which slots to play.
