Books have been set forth on this topic, and the disquiet and disagreement about where the "hot" slot machine games are positioned in a casino are still happening – over sixty yrs after slots were 1st installed in the casinos.
The classic rule is that the very best one armed bandits were positioned just inside the main entry of the casino; so that everyone passing by would be able to see actual jackpot winners … be intrigued enough to come into the casino … play. Our thought is that this is definitely no longer the case.
The majority of the mega casinos today are mammoth 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 near any exits.
An additional standard rule is that loose slot games are located on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be motivated to play. Importantly however, 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 slots 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slot machine games.
