Slot Machine positioning
Books have been written on this topic, and the debates and disharmony about where the "hot" slot machines are installed in the casino are still bubbling – 60 years after the slot machines were 1st placed in gambling dens.
The classic rule is that the superior slot games were positioned just inside the main entrance of the casino; so that casino fanatics passing by would see real jackpot winners … be challenged to come inside … play. Our deduction is that this is definitely no longer the case.
Most of the large casinos these days are monstrous complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slots near any entrances.
Yet another traditional rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more persons could see winning jackpots and be roused to play. Importantly though, 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 slot machine 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
