Casino visitors who played the slots in Colorado, New York, and Delaware will also see higher-than-average payback percentages.

Gaming rules vary by state, with some states requiring full disclosure of slot payback percentages per casino, while others lack requirements at all. States that don't require casinos to release payback percentage information may mandate a minimum payback percentage statewide, with casinos free to pay out above the minimum as desired. Twelve states fall into this category; listed from highest payout to lowest, they are Kansas (87%), Maryland (87%), Florida (85%), North Carolina (83%), Arizona (80%), Massachusetts (80%), Minnesota (80%), Montana (80%), New Mexico (80%), North Dakota (80%), Wisconsin (80%), and Michigan (75%).

That's right, if you choose to play slot machines in Michigan, you should know state gaming regulations have set the minimum payback percentage at 75% � the lowest in the U.S. That doesn't mean that any slot machines in the state will pay out at 75%, but legally, they're allowed to.

How Much Do You Want to Bet?

A Winning Streak on Slots

A well-known rule of thumb is that you reap what you sow the more you risk, the higher your potential reward. When we compared the denomination of a slot machine bet and its average payback percentage, it was concluded slot machines do not necessarily follow this rule.

We looked at the relationship between a denomination and average winnings during slot machine play and found a correlation that is not entirely linear. A $10 wager will offer higher approximate earnings than most other bets, including $100 bets. For the most part, however, higher denomination wagers typically offer higher average payback percentages than slots that accept lower bets.
