Volumes have been written on this topic, and the contention and ruckus about where the "hot" slot games are located in a casino are still bubbling – over 60 years after slot machine games were 1st added to the gaming floor in casinos.
The quintessential rule is that the very best one armed bandits were placed just inside the main foyer of the casino; so that fun seekers going by would see jackpot winners and be attracted to come unto the gaming floor and play. Our resolution is that this is no longer true.
The majority of the mega casinos presently are herculean complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slots near to any entrances or exits.
Another classic rule is that loose slot machines are positioned on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be influenced to play. Nonetheless, we find that this also isn’t 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 machine 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
