Books have been set forth on this item, and the controversy and discord about where the "hot" slot machine games are located in the casino are still bubbling – sixty years after slots were 1st placed in gambling dens.
The classic rule is that the best slots were positioned just inside the main entry of the casino; so that casino fanatics going by would see jackpot winners and be captivated to come unto the gaming floor … play. Our leaning is that this is definitely no longer so.
Just about all of the large casinos today are humongous complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machine games near any doorways.
Yet another traditional rule is that loose slots are positioned on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be encouraged to play. Importantly however, 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 slot machines 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!
These days, casinos are constantly changing their philosophy about where to place the loose slot machine games.
