You can find information on the payback percentages of individual machines by checking online reviews or visiting sites that specialize in reviewing new games.

Put in a few dollars and see how much you get back over time; if you’re breaking even or better, then the machine is probably a good bet. If not, you should move on to another machine. If you’re unsure which type of machine to play, try out different types with various themes and varying levels of volatility. Getting to know the different types of slots will help you make more informed decisions and ultimately play longer and win more.
