Books have been said on this issue, and the controversy and disagreement about where the "hot" slots are located in a casino are still taking place – over sixty yrs after slot machine games were first installed in the casinos.

The traditional rule is that the best slots were placed just inside the entry of the casino; so that individuals walking by would be able to see real jackpot winners and be mesmerized enough to come inside and play. Our view is that this is not so anymore.

Nearly all of the big name casinos nowadays are monstrous complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machine games in close proximity to any of the doors.

An additional classic rule is that loose one armed bandits are installed on the major aisles inside the casinos, again so that more people could see winning jackpots and be encouraged to play. Nonetheless, we find that this also isn’t a universal rule any more.

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 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 perspective about where to place the loose slot machines.
