Books have been said on this issue, and the contention and disagreement about where the "hot" slot machine games are placed in the casino are still happening – more than sixty yrs after the slot machines were 1st installed in the casinos.

The quintessential rule is that the best slot machines were positioned just inside the door of the casino; so that everyone passing by would see actual jackpot winners and be convinced to come unto the gaming floor and play. Our inference is that this is definitely no longer the case.

Almost all of the big name casinos nowadays are huge complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots in close proximity to any exits.

An additional traditional rule is that loose slots are located on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be motivated to play. 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 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!

In recent times, casinos are constantly changing their philosophy about where to place the loose slot machine games.
