Books have been written on this item, and the debates and discussion about where the "hot" slot games are installed in a casino are still intense – over 60 years after the slot machines were first added to the gaming floor in casinos.

The traditional rule is that the more favourable one armed bandits were located just inside the entrance of the casino; so that everyone going by would be able to see real jackpot winners … be possessed to come unto the gaming floor and play. Our conclusion is that this is no longer true.

Practically all of the large casinos these days are humongous complexes … you can no longer see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games close to any of the doors.

Yet another standard rule is that loose slot games are installed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be energized to play. Nonetheless, 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 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!

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