Books have been set forth on this topic, and the disquiet and squabbling about where the "hot" slots are installed in a casino are still taking place – over sixty years after slots were 1st placed in gambling houses.

The traditional rule is that the most favorable slot machine games were placed just inside the door of the casino; so that persons walking by would be able to see real jackpot winners … be attracted to come unto the gaming floor and play. Our view is that this is definitely no longer true.

Many of the large casinos today are super-colossal complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines in close proximity to any of the doors.

Another traditional rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be motivated to play. Interestingly 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 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!

Today, casinos are constantly changing their perspective about where to place the loose slot machines.
