It's based on
RTG marketing documentation as well as posts from
RTG operators on this site. I list specific numbers on my site. For slots, I believe it is a choice of 95%, 97.5% and a lower one (probably 92.5%). There are other games without set payout option and instead a choice of rule differences. For example, in blackjack
RTG operators can choose any # of decks from 1 to 255 and can make those changes on the fly. However, a reputable casino probably wouldn't change the game rules without first informing the players.
RTG seems to have a hands off approach and let casino operators do whatever they want once they've bought the software. Most of us probably think this is a poor business decision, but making a poor business decision about software licensing doesn't mean their software is rigged. There are also reputable casinos that use
RTG like Bodog, Club World, and iNetBet. Would these reputable groups choose to use the SW, if they knew it was rigged?
