Volumes have been set forth on this issue, and the contention and feuds about where the "hot" slot games are installed in a casino are still taking place – more than 60 yrs after slot games were first placed in casinos.
The quintessential rule is that the superior slots were installed just inside the main foyer of the casino; so that casino fanatics passing by would be able to see real jackpot winners … be inspired to come unto the gaming floor … play. Our philosophy is that this is not so anymore.
Most of the mega casinos nowadays are massive complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot machines near any doors.
An additional traditional rule is that loose slots are located on the major aisles inside the casinos, again so that more people could see winning jackpots and be inspired to play. Nonetheless, 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 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 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 slot games.
