Books have been written on this matter, and the conflict and arguments about where the "hot" slots are located in a casino are still passionate – over sixty years after the slots were 1st added to the gaming floor in the casinos.

The quintessential rule is that the best slot machines were located just inside the main foyer of the casino; so that fun seekers going by would see real jackpot winners and be inspired to come into the casino and play. Our theorem is that this is not so anymore.

Almost all of the large casinos today are magnificent complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machine games close to any doorways.

Another standard rule is that loose one armed bandits are put on the major aisles inside the casinos, again so that more persons could see winning jackpots and be influenced to play. Importantly though, we find that this also is not 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 slot machines 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!

Today, casinos are constantly changing their philosophy about where to place the loose slot games.
