Volumes have been set forth on this topic, and the bickering and ruckus about where the "hot" slots are located in the casino are still happening – over 60 yrs after the slots were 1st placed in gambling houses.
The traditional rule is that the more favourable one armed bandits were put just inside the entrance of the casino; so that folks passing by would be able to see actual jackpot winners … be possessed to come unto the gambling floor and play. Our position is that this is no longer the case.
Almost all of the big name casinos presently are gigantic 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 near to any doorways.
Yet another classic rule is that loose slot machine games are positioned on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be motivated to play. Interestingly 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 the slot machines 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
