Books have been set forth on this subject, and the disquiet and feuds about where the "hot" slot machines are installed in a casino are still passionate – over 60 yrs after slot games were 1st added to the gaming floor in casinos.
The classic rule is that the more favourable slot machine games were located just inside the main doorway of the casino; so that persons passing by would see actual jackpot winners and be intrigued enough to come unto the gambling floor … play. Our leaning is that this is no longer true.
The majority of the large casinos today are jumbo complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machines close to any entrances.
Another standard rule is that loose one armed bandits are positioned on the major aisles in the casinos, again so that more people could see winning jackpots and be influenced to play. Notably though, 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slots.
