Books have been written on this matter, and the conflict and face-offs about where the "hot" video slots are located in the casino are still rampant – more than sixty years after slots were first installed in gambling dens.

The quintessential rule is that the better slots were located just inside the main entryway of the casino; so that people passing by would be able to see jackpot winners and be mesmerized enough to come inside and play. Our finding is that this is definitely no longer the case.

Almost all of the big name casinos presently are mammoth complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machines in close proximity to any doorways.

Another standard rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Notably though, 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 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 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 slots.
