Volumes have been set forth on this item, and the contention and face-offs about where the "hot" slots are installed in a casino are still taking place – over sixty yrs after slot games were 1st added to the gaming floor in gambling dens.
The classic rule is that the superior one armed bandits were placed just inside the main entry of the casino; so that everyone walking by would see real jackpot winners and be mesmerized enough to come into the casino and play. Our speculation is that this is definitely no longer so.
Practically all of the big name casinos these days are super-colossal complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ one armed bandits in close proximity to any entrances or exits.
Yet another standard rule is that loose slots are placed on the major aisles inside the casinos, again so that more persons could see winning jackpots and be motivated to play. Nonetheless, 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 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 machine games.
