Books have been set forth on this item, and the debates and discourse about where the "hot" slot games are positioned in a casino are still passionate – over 60 years after slot machine games were first placed in gambling dens.
The quintessential rule is that the superior slot machines were placed just inside the main entryway of the casino; so that potential players walking by would be able to see real jackpot winners … be tempted to come unto the gaming floor and play. Our perspective is that this is no longer the case.
Almost all of the big name casinos presently are grand complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot games close-by any doors.
Another classic rule is that loose slot machine games are installed on the major aisles inside the casinos, again so that more people could see winning jackpots and be roused to play. Importantly however, 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 slot machine 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!
These days, casinos are constantly changing their perspective about where to place the loose slot machines.
