Volumes have been set forth on this matter, and the debates and disharmony about where the "hot" slots are located in a casino are still rampant – over 60 yrs after slots were first added to the gaming floor in casinos.
The traditional rule is that the better slot machines were installed just inside the main foyer of the casino; so that individuals passing by would be able to see real jackpot winners … be captivated to come inside … play. Our resolve is that this is definitely no longer true.
Many of the mega casinos nowadays are humongous complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machine games close to any entrances.
An additional classic rule is that loose slot machines are installed on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Importantly however, 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 slots 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 machine games.
