Volumes have been written on this topic, and the bickering and disagreement about where the "hot" slot games are located in the casino are still raging – more than 60 years after slot games were 1st added to the gaming floor in gambling houses.
The standard rule is that the very best slot machine games were installed just inside the main entrance of the casino; so that casino fanatics going by would be able to see real jackpot winners … be smitten to come unto the gambling floor and play. Our assessment is that this is no longer the case.
The majority of the major casinos nowadays are oversized complexes … it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ one armed bandits near to any doorways.
An additional classic rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be inspired to play. Notably however, we find that this also is no longer a universal rule.
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 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 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose one armed bandits.
