Books have been said on this issue, and the debates and feuds about where the "hot" slot games are placed in a casino are still intense – over 60 years after slot machine games were 1st placed in casinos.

The traditional rule is that the superior slot machines were installed just inside the door of the casino; so that people walking by would be able to see actual jackpot winners … be stirred to come inside … play. Our resolution is that this is no longer true.

The great majority of the large casinos today are behemothic complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slots near to any of the doors.

An additional classic rule is that loose one armed bandits are installed on the major aisles in the casinos, again so that more folks could see winning jackpots and be influenced to play. Importantly 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 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!

These days, casinos are constantly changing their perspective about where to place the loose slot machines.
