Books have been said on this matter, and the disquiet and feuds about where the "hot" one armed bandits are positioned in a casino are still passionate – 60 years after slots were 1st installed in gambling dens.

The traditional rule is that the most favorable slots were put just inside the main entryway of the casino; so that potential gamblers going by would be able to see actual jackpot winners … be smitten to come unto the gambling floor … play. Our finding is that this is not so anymore.

Almost all of the major casinos nowadays are jumbo complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots near any doors.

Another classic rule is that loose slot games are placed on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be energized to play. Nonetheless, 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 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 philosophy about where to place the loose one armed bandits.
