Slot Machine positioning
Books have been set forth on this matter, and the contention and discussion about where the "hot" video slots are located in a casino are still bubbling – over 60 yrs after slots were 1st added to the gaming floor in gambling houses.
The classic rule is that the better slot machines were put just inside the entrance of the casino; so that casino fanatics walking by would be able to see jackpot winners and be stirred to come into the casino and play. Our leaning is that this is not so anymore.
Almost all of the large casinos today are monstrous complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots near to any entrances or exits.
Yet another traditional rule is that loose slots are placed on the major aisles inside the casinos, again so that more people could see winning jackpots and be energized to play. Nonetheless, 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 the 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!
Today, casinos are constantly changing their perspective about where to place the loose one armed bandits.
