Books have been set forth on this item, and the contention and disharmony about where the "hot" slots are installed in the casino are still raging – sixty years after the slot machines were 1st added to the gaming floor in the casinos.
The standard rule is that the very best slot machine games were put just inside the main entrance of the casino; so that folks passing by would be able to see actual jackpot winners and be infatuated enough to come unto the gaming floor and play. Our stance is that this is definitely no longer the case.
Almost all of the mega casinos presently are mammoth complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ one armed bandits near to any of the doors.
An additional classic rule is that loose slot games are placed on the major aisles in the casinos, again so that more folks could see winning jackpots and be galvanized to play. Importantly though, 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 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!
In recent times, casinos are constantly changing their perspective about where to place the loose slot machines.
