Books have been stated on this item, and the disquiet and discord about where the "hot" slot machine games are positioned in a casino are still intense – more than 60 yrs after slot machine games were first added to the gaming floor in gambling houses.
The classic rule is that the better slot machine games were installed just inside the entrance of the casino; so that fun seekers passing by would see jackpot winners and be convinced to come unto the gambling floor and play. Our belief is that this is not so anymore.
Just about all of the big name casinos today are super-colossal complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot games close to any of the doors.
An additional traditional rule is that loose slot machine games are placed on the major aisles inside the casinos, again so that more people could see winning jackpots and be energized to play. Nonetheless, we find that this also is no longer a universal rule.
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 the slots 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!
Today, casinos are constantly changing their perspective about where to place the loose slot machines.
