Volumes have been set forth on this subject, and the controversy and discord about where the "hot" slot games are placed in a casino are still raging – more than sixty years after the slot machines were 1st added to the gaming floor in gambling dens.
The classic rule is that the most favorable slot machine games were installed just inside the main entry of the casino; so that potential players passing by would be able to see real jackpot winners and be enthralled to come into the casino … play. Our belief is that this is no longer true.
The majority of the large casinos presently are mammoth complexes … it is not possible to see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot machine games near any doorways.
Another classic rule is that loose slot machine games are positioned on the major aisles in the casinos, again so that more persons could see winning jackpots and be energized to play. Importantly however, 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 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!
Today, casinos are constantly changing their perspective about where to place the loose one armed bandits.
