Yeah, in the context that regulated and licensed online casinos must adhere to the strictest business policies in order to be issued operating licenses. The online casino industry is governed by regulators, watchdogs, and rules, and its games are audited by third parties. The games are not “set” in the sense that each spin is genuinely unpredictable and gives you the same chances of winning every time.
Of course, the house always has an advantage of about 3%, allowing them to win money in the long run, but you’ll also find that this gives a higher payoff to the buyer than the land-based slots in Vegas. While there might be some uncontrolled rogue casinos out there, we just suggest trustworthy ones. That is our responsibility! However, as in any poker game, you risk losing money, so just play with money you can afford to lose.
