Books have been said on this subject, and the controversy and disharmony about where the "hot" video slots are located in a casino are still passionate – over sixty yrs after slot games were first placed in the casinos.
The quintessential rule is that the most favorable slots were located just inside the entry of the casino; so that individuals going by would see jackpot winners … be inspired to come unto the gaming floor … play. Our interpretation is that this is no longer true.
Nearly all of the mega casinos presently are colossal complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot games near to any exits.
Yet another classic rule is that loose slot games are installed on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Importantly though, 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 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slots.
