Books have been set forth on this item, and the contention and discussion about where the "hot" slot machine games are positioned in the casino are still bubbling – 60 years after one armed bandits were 1st placed in gambling houses.
The classic rule is that the best one armed bandits were installed just inside the main entry of the casino; so that everyone going by would see real jackpot winners … be tempted to come unto the gaming floor … play. Our determination is that this is definitely no longer the case.
Most of the large casinos today are gigantic complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slot games close to any of the doors.
Another classic rule is that loose slot games are placed on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be motivated 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 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!
In recent times, casinos are constantly changing their perspective about where to place the loose one armed bandits.
