Volumes have been set forth on this matter, and the bickering and disharmony about where the "hot" one armed bandits are positioned in the casino are still happening – more than 60 years after slot machine games were 1st placed in casinos.
The standard rule is that the more favourable slots were put just inside the entrance of the casino; so that folks passing by would see real jackpot winners … be challenged to come unto the gambling floor and play. Our standpoint is that this is definitely no longer the case.
Almost all of the major casinos presently are grand complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slots in close proximity to any entrances.
Yet another traditional 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 galvanized 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 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slot games.
