Volumes have been stated on this topic, and the contention and disharmony about where the "hot" one armed bandits are located in the casino are still on-going – over 60 yrs after slots were 1st added to the gaming floor in casinos.
The quintessential rule is that the most favorable slot machine games were put just inside the main foyer of the casino; so that potential players going by would be able to see jackpot winners and be infatuated enough to come unto the gambling floor … play. Our deduction is that this is no longer true.
The majority of the mega casinos nowadays are titanic complexes … it is not possible to see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slots near to any exits.
An additional classic rule is that loose slot machines are located on the major aisles in the casinos, again so that more potential players could see winning jackpots and be inspired to play. Nonetheless, 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 slot 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!
Today, casinos are constantly changing their perspective about where to place the loose slots.
