Once the odds are set, the casino lives with them. Anything else would either look bad, expose the casinos to loss (you wouldn’t like it if they went out of business) or, in some countries, be a criminal offence. In the USA, the Nevada regulations which are adopted widely, require the RNG to work randomly with the software tested by regulatory authorities. Trying to shade the odds to change the probabilities in favour of the House is not allowed. The reputable online casinos are the same. The payout percentages are set within a range that is fair to both sides. Any change would be have to be approved by the online regulatory bodies.

So, the House makes its profit — that’s why they’re in business. If we want them to provide the opportunity to gamble, we need them to stay in business! Before you start playing, read the pay tables. Pick the slots that gives you best payback. Here’s where a little math comes in handy. You shouldn’t play any virtual machine that offers a payback of less than 95%. In the real world, casinos have very big overheads. Think of all that floor space and then all the staff, the power bills, and so on. When you go to play online slots, the operator’s overheads are a fraction of those in the real world. That means an online operator can make a good return on money invested and give you a higher rate of winnings than you could ever get in the real world!
