Volumes have been stated on this matter, and the controversy and disagreement about where the "hot" slot games are located in a casino are still taking place – more than 60 years after slot machine games were 1st placed in the casinos.
The quintessential rule is that the very best slot games were placed just inside the main entrance of the casino; so that everyone passing by would be able to see real jackpot winners and be enthralled to come unto the gaming floor and play. Our view is that this is definitely no longer so.
Just about all of the large casinos today are enormous complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games in close proximity to any doors.
Yet another standard rule is that loose slot machine games are installed on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. However, 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 the slot machines 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.
