Books have been stated on this issue, and the debates and discourse about where the "hot" slots are positioned in the casino are still bubbling – 60 yrs after one armed bandits were first installed in gambling dens.
The quintessential rule is that the better slot machines were placed just inside the main door of the casino; so that persons going by would see real jackpot winners … be smitten to come into the casino and play. Our estimation is that this is no longer true.
Nearly all of the major casinos presently are mammoth complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot games near to any entrances.
Another classic rule is that loose one armed bandits are positioned on the major aisles in the casinos, again so that more people could see winning jackpots and be encouraged 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 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 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 philosophy about where to place the loose slots.
