Books have been stated on this item, and the disquiet and discourse about where the "hot" one armed bandits are located in the casino are still raging – 60 yrs after the slots were 1st added to the gaming floor in gambling houses.
The classic rule is that the superior slots were installed just inside the main doorway of the casino; so that people walking by would be able to see actual jackpot winners … be mesmerized enough to come unto the gaming floor … play. Our theorem is that this is no longer the case.
The majority of the major casinos presently are mammoth complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ one armed bandits close-by any of the doors.
Yet another classic rule is that loose slot machines are put on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be energized 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 one armed bandits 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 slot games.
