Volumes have been said on this matter, and the bickering and discussion about where the "hot" slot machines are placed in the casino are still taking place – over sixty years after slot machines were first installed in gambling dens.
The classic rule is that the most favorable slots were located just inside the main door of the casino; so that casino fanatics passing by would see jackpot winners … be drawn to come unto the gambling floor … play. Our stance is that this is definitely no longer true.
Practically all of the big name casinos presently are giant complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machine games close-by any doorways.
Yet another traditional rule is that loose slot machine games are installed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be energized to play. Nonetheless, 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 the slot machines 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 perspective about where to place the loose slot machines.
