Volumes have been written on this topic, and the bickering and squabbling about where the "hot" slot machine games are installed in a casino are still on-going – over 60 years after the slot machines were first placed in gambling dens.
The standard rule is that the most favorable slot machine games were located just inside the door of the casino; so that people walking by would see real jackpot winners … be smitten to come unto the gambling floor … play. Our leaning is that this is definitely no longer true.
Practically all of the large casinos nowadays are mammoth complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machine games near to any entrances.
Another traditional rule is that loose slots are put on the major aisles in the casinos, again so that more people could see winning jackpots and be galvanized to play. Importantly though, 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 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 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 games.
