Volumes have been written on this matter, and the bickering and face-offs about where the "hot" slot machines are placed in a casino are still on-going – 60 years after slots were first installed in casinos.

The standard rule is that the more favourable slot games were located just inside the door of the casino; so that persons going by would see real jackpot winners and be possessed to come unto the gambling floor and play. Our reckoning is that this is definitely no longer true.

Most of the large casinos nowadays are gigantic complexes and 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 entrances or exits.

Yet another traditional rule is that loose slots are located on the major aisles in the casinos, again so that more persons could see winning jackpots and be roused to play. Nonetheless, 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 the 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 one armed bandits.
