Volumes have been said on this subject, and the conflict and squabbling about where the "hot" slot games are positioned in the casino are still intense – sixty years after slot games were first added to the gaming floor in gambling houses.
The standard rule is that the most favorable slot games were put just inside the main entry of the casino; so that persons walking by would be able to see jackpot winners … be attracted to come inside … play. Our theorem is that this is no longer the case.
The great majority of the mega casinos these days are jumbo complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot machine games close-by any doors.
An additional traditional rule is that loose slots are put on the major aisles in the casinos, again so that more folks could see winning jackpots and be influenced to play. However, we find that this also is no longer a universal rule.
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 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 slots.
