Not much can be said about it. It is almost automatic by now. I do not see the attraction. Unless it is one of those poker machines. I can see that to a certain extend. i always looked at that as entertainment rather than gambling. Now there are machine that you fill with money and after that it is all automatic. There are rumours from time to time about casinos paying more than others. I do not buy into that. I think every casino takes as much as the law allows. Yes, slot machine payouts have to have a certain minimum. The gaming Control Board sets it. If not there may be an operator who does not pay out anything at all. Las Vegas cannot afford that reputation. Have you made money on slots/ Let us know where, it is good advertising for that casino. I never have personally. I always lost, year after year.
