Volumes have been written on this issue, and the conflict and face-offs about where the "hot" slot games are positioned in a casino are still there – 60 years after slot machines were 1st added to the gaming floor in gambling dens.
The classic rule is that the very best slot games were installed just inside the main entry of the casino; so that individuals passing by would see real jackpot winners and be enthralled to come unto the gaming floor and play. Our assessment is that this is definitely no longer true.
The majority of the large casinos today are monstrous complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machines near any exits.
Yet 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 energized to play. Nonetheless, 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 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 perspective about where to place the loose slots.
