Volumes have been written on this topic, and the debates and disagreement about where the "hot" slot games are located in the casino are still taking place – over sixty years after the slot machines were 1st placed in the casinos.
The classic rule is that the better slots were positioned just inside the main foyer of the casino; so that individuals going by would see jackpot winners … be attracted to come unto the gambling floor … play. Our slant is that this is definitely no longer the case.
Just about all of the big name casinos nowadays are humongous complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot games close to any entrances.
An additional traditional rule is that loose slot games are positioned on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be motivated 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 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 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 slot machine games.
