Books have been written on this subject, and the debates and disagreement about where the "hot" one armed bandits are positioned in a casino are still passionate – more than sixty yrs after slot machines were first added to the gaming floor in gambling dens.

The classic rule is that the best slot machines were installed just inside the main door of the casino; so that potential gamblers passing by would see real jackpot winners … be mesmerized enough to come unto the gambling floor … play. Our observation is that this is not so anymore.

Almost all of the major casinos these days are immense complexes and it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machines close-by any doorways.

Yet another traditional rule is that loose slot machines are positioned on the major aisles inside the casinos, again so that more people could see winning jackpots and be motivated 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 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 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!

Nowadays, casinos are constantly changing their philosophy about where to place the loose slot machine games.
