Books have been written on this issue, and the bickering and feuds about where the "hot" one armed bandits are positioned in a casino are still there – more than sixty years after the slots were first installed in casinos.

The quintessential rule is that the better one armed bandits were put just inside the main entryway of the casino; so that persons passing by would see jackpot winners … be possessed to come inside and play. Our observation is that this is no longer true.

The great majority of the major casinos today are giant complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot machine games close to any exits.

An additional traditional rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be energized 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!

Nowadays, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
