Volumes have been written on this issue, and the disquiet and squabbling about where the "hot" slot machine games are installed in the casino are still passionate – over 60 years after the slot machines were 1st placed in the casinos.
The quintessential rule is that the very best slot games were installed just inside the main entrance of the casino; so that potential players passing by would be able to see real jackpot winners and be intrigued enough to come unto the gambling floor and play. Our sentiment is that this is definitely no longer true.
Most of the big name casinos presently are monstrous complexes … it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slots near any doors.
Yet another classic rule is that loose slot machine games are located on the major aisles inside the casinos, again so that more folks could see winning jackpots and be inspired to play. Notably though, 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 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slot machine games.
