Volumes have been stated on this subject, and the debates and interchanges about where the "hot" one armed bandits are located in the casino are still there – over sixty years after slot machines were first placed in gambling houses.
The classic rule is that the more favourable one armed bandits were installed just inside the door of the casino; so that folks passing by would be able to see real jackpot winners … be challenged to come into the casino and play. Our verdict is that this is not so anymore.
The great majority of the mega casinos these days are titanic complexes and you can no longer see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot games close to any doorways.
An additional classic rule is that loose slot machine games are located on the major aisles in the casinos, again so that more potential players could see winning jackpots and be galvanized to play. Importantly though, 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 one armed bandits 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slots.
