If you've spent much time near slot machines at a land casino, then perhaps you've seen a sign advertising fantastic return rates like: "up to 99% payouts!" These are common ways for casinos to show players that they offer a relatively high average rate of return on all credits wagered, across all slots games.

But what does 99% payouts really mean? What the casinos won't tell you is exactly how much a given machine pays, and also what the overall rate of return is for any slot. One machine could be paying out only 85% while the one beside it could be returning 100%+. Unless you subscribe to a major gambling publication which lists the periodical payout rates of land casinos, then chances are you play in good faith that a casino is living up to their end of the bargain when it comes to slot payouts.

Online casinos by Microgaming are different in that all games, including slot machines, are audited monthly by one of the world's largest accounting firms. These "monthly audit reports" are then published online at just about every casino website. They are there for your viewing and can be an important factor in choosing your preferred casino. While the payout odds for any slots game are truly random at any moment, ask yourself if you would rather be playing at a casino who's return rate held steady in the high 90's for the past few months, or at a place whose percentage only hovered around 92%.

Thanks to the internet, this information is now widely available, and you may browse the payout reports of all the casinos found on this website by using the links to the right.
