Volumes have been set forth on this subject, and the bickering and discourse about where the "hot" slot machines are installed in a casino are still happening – sixty yrs after slot machine games were 1st placed in casinos.
The standard rule is that the very best slot machine games were located just inside the main entrance of the casino; so that persons passing by would be able to see real jackpot winners … be attracted to come inside and play. Our conclusion is that this is not so anymore.
Nearly all of the major casinos nowadays are immense complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot games near any doors.
An additional classic rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more folks could see winning jackpots and be influenced to play. Notably 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 slot games 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.
