Volumes have been set forth on this item, and the conflict and squabbling about where the "hot" slot games are placed in a casino are still passionate – sixty years after the slot machines were 1st added to the gaming floor in casinos.
The standard rule is that the superior slot machines were placed just inside the main door of the casino; so that potential players going by would see real jackpot winners and be attracted to come inside and play. Our disposition is that this is definitely no longer true.
Just about all of the large casinos today are colossal complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot games near any exits.
An additional traditional rule is that loose one armed bandits are positioned 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 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 the 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 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 slot games.
