Books have been set forth on this topic, and the disquiet and interchanges about where the "hot" slot machine games are placed in the casino are still intense – sixty years after the slot machines were first added to the gaming floor in the casinos.

The standard rule is that the superior slot machines were located just inside the main entrance of the casino; so that everyone passing by would see real jackpot winners … be challenged to come unto the gambling floor … play. Our reckoning is that this is no longer true.

The majority of the large casinos these days are oversized complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machine games in close proximity to any exits.

An additional traditional rule is that loose one armed bandits are located on the major aisles in the casinos, again so that more potential players could see winning jackpots and be motivated 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 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!

These days, casinos are constantly changing their perspective about where to place the loose slot games.
