Volumes have been set forth on this item, and the contention and squabbling about where the "hot" one armed bandits are placed in a casino are still passionate – sixty yrs after one armed bandits were 1st added to the gaming floor in casinos.
The standard rule is that the superior slot machines were put just inside the main entrance of the casino; so that casino fanatics passing by would see jackpot winners and be stirred to come into the casino and play. Our presumption is that this is not so anymore.
Many of the big name casinos nowadays are giant complexes … it is not possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot games near any doors.
Yet 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 galvanized to play. Importantly though, we find that this also isn’t 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slots.
