Volumes have been written on this issue, and the debates and discourse about where the "hot" slot machines are installed in a casino are still happening – 60 yrs after one armed bandits were first placed in gambling dens.

The quintessential rule is that the most favorable one armed bandits were installed just inside the main doorway of the casino; so that casino fanatics walking by would see real jackpot winners … be mesmerized enough to come inside … play. Our belief is that this is no longer true.

Almost all of the major casinos presently are enormous complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot machine games close-by any exits.

An additional classic rule is that loose slot machine games are put on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be inspired to play. However, 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 one armed bandits 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 perspective about where to place the loose one armed bandits.
