Books have been set forth on this issue, and the disquiet and face-offs about where the "hot" slot machines are positioned in a casino are still rampant – over sixty years after the slot machines were 1st placed in gambling dens.

The classic rule is that the most favorable slot machines were placed just inside the main entryway of the casino; so that potential players passing by would see real jackpot winners and be stimulated to come unto the gaming floor … play. Our conviction is that this is no longer the case.

The great majority of the big name casinos presently are jumbo complexes … it is not possible to see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ one armed bandits near to any of the doors.

An additional standard rule is that loose slots are located on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be inspired to play. Importantly 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!

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