Volumes have been stated on this item, and the controversy and discussion about where the "hot" slot machines are positioned in the casino are still rampant – 60 years after one armed bandits were first placed in gambling dens.
The standard rule is that the superior one armed bandits were installed just inside the door of the casino; so that casino fanatics walking by would be able to see real jackpot winners and be influenced to come unto the gaming floor and play. Our deduction is that this is definitely no longer the case.
Just about all of the major casinos presently are mammoth complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ one armed bandits in close proximity to any entrances or exits.
Another classic rule is that loose one armed bandits are placed on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be encouraged to play. Nonetheless, we find that this also isn’t 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 slot machine games 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!
Today, casinos are constantly changing their perspective about where to place the loose slot games.
