Books have been written on this subject, and the bickering and squabbling about where the "hot" slot games are installed in the casino are still taking place – sixty yrs after slot games were 1st added to the gaming floor in the casinos.
The standard rule is that the very best one armed bandits were located just inside the main door of the casino; so that casino fanatics walking by would see actual jackpot winners and be influenced to come unto the gaming floor and play. Our stance is that this is definitely no longer the case.
Just about all of the major casinos today are huge complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slots close-by any entrances or exits.
Yet another classic rule is that loose slot machine games are positioned on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be influenced to play. Interestingly though, we find that this also is not 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 philosophy about where to place the loose slots.
