Volumes have been written on this issue, and the disquiet and discord about where the "hot" slot machines are positioned in a casino are still bubbling – more than 60 years after the slots were 1st added to the gaming floor in casinos.
The classic rule is that the best slot games were installed just inside the main doorway of the casino; so that individuals going by would be able to see jackpot winners and be smitten to come unto the gambling floor and play. Our belief is that this is definitely no longer so.
Many of the major casinos presently are mammoth complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slots in close proximity to any doors.
Yet another standard rule is that loose slot machine games are installed on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be motivated to play. Importantly though, 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 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 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.
