Volumes have been said on this item, and the contention and interchanges about where the "hot" slot machine games are placed in a casino are still passionate – sixty yrs after the slot machines were 1st added to the gaming floor in casinos.
The traditional rule is that the most favorable slot machines were placed just inside the entry of the casino; so that fun seekers passing by would be able to see actual jackpot winners and be aroused to come unto the gambling floor and play. Our theorem is that this is no longer the case.
Practically all of the major casinos these days are magnificent complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machines in close proximity to any doorways.
Another standard rule is that loose slot machine games are located on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. Importantly however, 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 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.
