Slot Machine positioning
Books have been set forth on this subject, and the contention and disharmony about where the "hot" slot games are installed in the casino are still bubbling – sixty yrs after slot machines were 1st placed in casinos.
The classic rule is that the superior slots were put just inside the main entrance of the casino; so that fun seekers going by would see actual jackpot winners … be challenged to come unto the gambling floor and play. Our reasoning is that this is definitely no longer the case.
Practically all of the major casinos presently are behemothic complexes … it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machine games near any exits.
Another classic rule is that loose slots are placed on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be motivated to play. Importantly however, 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose one armed bandits.
