Books have been written on this matter, and the disquiet and discussion about where the "hot" one armed bandits are located in the casino are still rampant – over 60 yrs after slot games were first added to the gaming floor in casinos.

The classic rule is that the best slot machine games were placed just inside the entrance of the casino; so that people passing by would see real jackpot winners … be drawn to come unto the gaming floor and play. Our leaning is that this is definitely no longer true.

The great majority of the big name casinos today are enormous complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ one armed bandits close to any entrances or exits.

An additional traditional rule is that loose slot machines are installed on the major aisles in the casinos, again so that more potential players could see winning jackpots and be galvanized to play. Interestingly though, we find that this also is no longer a universal rule.

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 slot machine games 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!

In recent times, casinos are constantly changing their perspective about where to place the loose slots.
