Books have been said on this subject, and the bickering and disharmony about where the "hot" slot machines are installed in a casino are still taking place – more than 60 yrs after slot machines were 1st placed in gambling houses.
The quintessential rule is that the best slot machines were put just inside the main door of the casino; so that potential players going by would see jackpot winners … be titillated to come inside … play. Our reasoning is that this is definitely no longer true.
The majority of the mega casinos these days are immense complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slots in close proximity to any exits.
Another classic rule is that loose slot machine games are installed on the major aisles inside the casinos, again so that more persons could see winning jackpots and be motivated to play. 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 one armed bandits 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 philosophy about where to place the loose slot machine games.
