Volumes have been set forth on this topic, and the bickering and ruckus about where the "hot" slot machine games are placed in a casino are still rampant – 60 yrs after slot machine games were 1st placed in gambling dens.
The standard rule is that the more favourable slots were placed just inside the main doorway of the casino; so that folks walking by would see real jackpot winners … be mesmerized enough to come inside … play. Our perspective is that this is definitely no longer true.
Nearly all of the major casinos today are oversized complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines near any doorways.
Another classic rule is that loose slot machines are put on the major aisles inside the casinos, again so that more folks could see winning jackpots and be galvanized 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 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 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 one armed bandits.
