The medium slot percentage payout in Vegas is 75%. However, there seems to be an ambiguity as to the correct percentage payout. In my recent article about “What is the Payout Percentage of Slot Machines,” I mentioned that not all slot machines are equal; that one slot machine may pay off a higher percentage than the same slot machine located in a different area of the casino. The pay out percentage in Vegas is also determined by location, that is, where the casino is located – either downtown, on the strip, in Boulder, or in North Las Vegas. The payout percentages are all over the map. To this end, I am going to list below the payout percentages based on wagers at different locations in Vegas. These are approximate RTPs and are over a year old.
