Volumes have been set forth on this subject, and the bickering and discord about where the "hot" slot machine games are positioned in the casino are still intense – over 60 yrs after the slots were first added to the gaming floor in gambling houses.
The classic rule is that the more favourable one armed bandits were positioned just inside the entry of the casino; so that casino fanatics passing by would see actual jackpot winners and be smitten to come inside and play. Our philosophy is that this is definitely no longer true.
The great majority of the big name casinos nowadays are huge complexes and you can no longer see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ one armed bandits in close proximity to any entrances.
Yet another traditional rule is that loose slot machines are positioned on the major aisles inside the casinos, again so that more folks could see winning jackpots and be inspired 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 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!
In recent times, casinos are constantly changing their perspective about where to place the loose slot games.
