Books have been set forth on this issue, and the bickering and disharmony about where the "hot" video slots are positioned in the casino are still intense – more than 60 years after the slots were 1st added to the gaming floor in the casinos.
The traditional rule is that the superior one armed bandits were located just inside the main door of the casino; so that individuals passing by would see jackpot winners … be enthralled to come inside … play. Our conviction is that this is definitely no longer so.
Practically all of the big name casinos nowadays are gigantic complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slots near to any of the doors.
An additional classic rule is that loose slot machine games are put on the major aisles inside the casinos, again so that more people could see winning jackpots and be inspired to play. Importantly however, 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.
