There are a few different ways to try and determine how much Americans are winning on casino games. We can try to look at different data on revenues, wins, and prizes, though we decided to opt for a more reliable method.

To find out the casino payouts by state, this article will review the return-to-player (RTP) percentages in different casinos across the United States. Note that in most cases, tribal casinos don’t report their payout percentages, so we only collected data from commercial casinos.

RTP is the percentage of prizes returned to the players from the money initially deposited. As such, it can be used as a tool that can provide valuable information on casino payouts and shed some light on exactly how much money players are winning in each state.

Casino Payouts by State

The regulatory authorities across different states have payout percentage requirements that range around 80% and 85%. This means that casinos must return 80% to 85% of the money deposited from the players, back to them as winnings.

Let’s have a look at the reported RTP percentages across the many casinos around the country and see just how much money players are winning.
