Volumes have been set forth on this matter, and the disquiet and disharmony about where the "hot" video slots are installed in a casino are still intense – more than sixty years after the slots were first placed in gambling dens.
The classic rule is that the better slot machines were put just inside the main door of the casino; so that people passing by would see real jackpot winners … be drawn to come inside … play. Our viewpoint is that this is not so anymore.
Nearly all of the big name casinos these days are behemothic complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machines near to any exits.
Yet another classic rule is that loose slot games are placed on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. Nonetheless, 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 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 very 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 one armed bandits.
