Wow. Virtual Ted is answering questions and now that he no longer works there i am sure they are true.
One big thing he says is YES RTG software does allow for casino to set payout %!!!!!! But he says there are only 3 settings. 93%, 95%, and 97%.
Also, he says they cannot set separate payout %s for individual players. In other words whatever its set at, all players are playing that %. He said he kept theirs at 97% most of the time!!
When you consider that Atlantic City casinos average about 92% payout on .25 machines, 93,95,97 are good payouts. I have always thought online slots had better payouts than B&M's. This confirms it. Makes sense since they have lower overhead.
He also said they can set the # of decks in blackjack (not for individual players though) anywhere from 1 to 250 decks!!!!! He said he kept his at 4.
Its really nice to find out some of the "behind the scenes" stuff about both Virtual and RTG in general.
