Volumes have been said on this issue, and the controversy and arguments about where the "hot" slot machine games are positioned in a casino are still bubbling – 60 years after slot games were first added to the gaming floor in the casinos.
The quintessential rule is that the best slots were positioned just inside the entry of the casino; so that potential players walking by would be able to see real jackpot winners … be infatuated enough to come unto the gaming floor … play. Our sentiment is that this is no longer true.
Almost all of the major casinos today are giant complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games near to any of the doors.
Yet another traditional rule is that loose slot games are put on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. Notably however, we find that this also is not a universal rule any more.
What casinos found over the years is that people walking down the busy aisles were frequently on the way to somewhere else. If they played one armed bandits at all, they would simply put in their loose change because they happened to be walking by. Win or lose, they would very often not stop to keep playing. And the very last thing a casino wants is for someone to win a jackpot by playing only a few coins and then not stay to put it all back in!
In recent times, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
