Volumes have been set forth on this matter, and the conflict and interchanges about where the "hot" slot machine games are placed in the casino are still bubbling – sixty years after slot machine games were 1st placed in casinos.
The classic rule is that the best one armed bandits were positioned just inside the main doorway of the casino; so that persons passing by would be able to see jackpot winners … be convinced to come unto the gambling floor and play. Our position is that this is no longer true.
Most of the major casinos nowadays are massive complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machine games near any entrances.
Yet another classic rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be influenced 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 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!
These days, casinos are constantly changing their philosophy about where to place the loose slot games.
