Volumes have been said on this topic, and the disquiet and squabbling about where the "hot" slot machine games are positioned in a casino are still taking place – more than 60 years after the slots were 1st added to the gaming floor in the casinos.
The standard rule is that the more favourable slot games were put just inside the main foyer of the casino; so that individuals going by would see jackpot winners … be enticed to come unto the gambling floor … play. Our belief is that this is no longer the case.
The majority of the large casinos presently are monstrous complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ one armed bandits in close proximity to any of the doors.
An additional classic rule is that loose slots are installed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be encouraged to play. Interestingly though, 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 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 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!
These days, casinos are constantly changing their philosophy about where to place the loose slot machines.
