Volumes have been set forth on this item, and the disquiet and disharmony about where the "hot" slot machines are positioned in the casino are still bubbling – sixty yrs after the slots were 1st placed in gambling houses.
The quintessential rule is that the better slot machine games were placed just inside the main entry of the casino; so that folks walking by would see actual jackpot winners … be attracted to come into the casino and play. Our belief is that this is no longer true.
Almost all of the mega casinos presently are herculean complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slots close-by any exits.
Another classic rule is that loose slots are positioned on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Interestingly 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 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 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose slots.
