Actually the study only says that the Palms had the lowest nickel video slotsof the casinos surveyed in Las Vegas. The'.' in the sign encompases quite a bit of information,which was conveniently left off the sign. Although I did the study Anthony Curtis published it in the LasVegas Advisor, which is how it become well known. The above sign can be found across the street from the Palms.
The next table shows the average return by location. I can not include any casino that prohibits the method in which I gather data. The Suncoast and Rampart Casino in Summerlin do not allow playing slots and taking notes at the same time.
