Volumes have been stated on this item, and the bickering and discord about where the "hot" slot machines are positioned in the casino are still intense – sixty years after slots were first added to the gaming floor in casinos.
The classic rule is that the better slot games were positioned just inside the main entrance of the casino; so that potential gamblers going by would see jackpot winners and be attracted to come unto the gaming floor and play. Our theorem is that this is definitely no longer so.
Most of the major casinos today are jumbo complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines near any of the doors.
An additional traditional rule is that loose slot machine games are installed on the major aisles in the casinos, again so that more potential players could see winning jackpots and be motivated to play. Notably though, 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 slot machine 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slots.
