Books have been stated on this issue, and the controversy and ruckus about where the "hot" slot games are located in the casino are still bubbling – sixty yrs after one armed bandits were 1st added to the gaming floor in the casinos.
The quintessential rule is that the better slot machine games were installed just inside the main entryway of the casino; so that everyone passing by would see real jackpot winners … be infatuated enough to come unto the gaming floor … play. Our determination is that this is definitely no longer true.
Almost all of the big name casinos nowadays are titanic complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot games close-by any entrances.
Yet another traditional rule is that loose slot games are placed on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be energized to play. Importantly however, 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!
Today, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
