Volumes have been stated on this item, and the conflict and squabbling about where the "hot" slots are installed in the casino are still there – 60 years after slot machines were 1st installed in the casinos.
The quintessential rule is that the best one armed bandits were installed just inside the entrance of the casino; so that potential players walking by would see real jackpot winners and be drawn to come into the casino … play. Our philosophy is that this is definitely no longer the case.
Most of the major casinos nowadays are jumbo complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ one armed bandits near any entrances or exits.
Yet another classic rule is that loose slot machines are put on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. Importantly however, 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 machine 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!
These days, casinos are constantly changing their perspective about where to place the loose slot machine games.
