Slot Machine Location
Books have been set forth on this item, and the controversy and disagreement about where the "hot" slot machines are placed in the casino are still raging – sixty yrs after the slot machines were first installed in the casinos.
The standard rule is that the most favorable slot machine games were positioned just inside the main doorway of the casino; so that fun seekers going by would be able to see actual jackpot winners … be stimulated to come inside … play. Our inference is that this is definitely no longer the case.
Just about all of the large casinos these days are titanic complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot games close-by any doors.
Another standard rule is that loose slots are positioned on the major aisles in the casinos, again so that more people could see winning jackpots and be energized to play. Notably however, 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 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 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 one armed bandits.
