Volumes have been set forth on this matter, and the bickering and discussion about where the "hot" video slots are installed in the casino are still bubbling – over sixty years after slots were 1st installed in casinos.
The quintessential rule is that the superior slots were placed just inside the main entry of the casino; so that people passing by would be able to see jackpot winners … be influenced to come into the casino and play. Our resolution is that this is no longer the case.
Almost all of the major casinos today are humongous complexes and it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slots near to any exits.
An additional traditional rule is that loose slot machines are positioned on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be inspired to play. Importantly however, 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!
Today, casinos are constantly changing their perspective about where to place the loose slots.
