Volumes have been said on this subject, and the conflict and discourse about where the "hot" video slots are located in a casino are still bubbling – more than sixty years after slot machine games were first placed in gambling dens.
The traditional rule is that the very best slot machines were located just inside the main entry of the casino; so that persons walking by would be able to see actual jackpot winners … be aroused to come unto the gambling floor and play. Our estimation is that this is no longer the case.
Just about all of the big name casinos today are titanic complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot games in close proximity to any entrances or exits.
An additional classic rule is that loose one armed bandits are positioned on the major aisles in the casinos, again so that more persons could see winning jackpots and be motivated 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!
In recent times, casinos are constantly changing their perspective about where to place the loose slot machines.
