Volumes have been set forth on this subject, and the debates and feuds about where the "hot" slot machine games are located in the casino are still happening – over 60 years after slot machine games were first placed in the casinos.
The standard rule is that the better slot games were placed just inside the main entrance of the casino; so that people going by would see real jackpot winners … be mesmerized enough to come unto the gaming floor … play. Our inclination is that this is no longer the case.
Many of the big name casinos these days are gigantic complexes … you can no longer see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot machines close to any of the doors.
An additional classic rule is that loose slot machines are located on the major aisles inside the casinos, again so that more folks could see winning jackpots and be encouraged to play. Nonetheless, 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 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 philosophy about where to place the loose slot machines.
