Books have been said on this item, and the debates and arguments about where the "hot" one armed bandits are placed in the casino are still taking place – more than sixty years after the slots were 1st installed in gambling houses.
The classic rule is that the best slot games were put just inside the main foyer of the casino; so that potential gamblers walking by would see jackpot winners and be titillated to come into the casino … play. Our standpoint is that this is definitely no longer the case.
Just about all of the mega casinos today are enormous complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machines in close proximity to any entrances.
Yet another classic rule is that loose one armed bandits are installed on the major aisles inside the casinos, again so that more persons could see winning jackpots and be energized to play. Interestingly 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 slot 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 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!
Today, casinos are constantly changing their perspective about where to place the loose slot games.
