Volumes have been written on this issue, and the bickering and disagreement about where the "hot" slot machines are placed in a casino are still on-going – sixty yrs after the slot machines were 1st added to the gaming floor in the casinos.
The traditional rule is that the very best slot games were placed just inside the main foyer of the casino; so that persons passing by would be able to see actual jackpot winners … be impressed enough to come inside and play. Our belief is that this is no longer the case.
Just about all of the big name casinos today are enormous complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot games near to any of the doors.
Yet another traditional rule is that loose slot machine games are installed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be roused to play. Importantly 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 one armed bandits 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 perspective about where to place the loose slot machines.
