Books have been said on this matter, and the bickering and arguments about where the "hot" video slots are located in the casino are still there – sixty years after one armed bandits were first added to the gaming floor in the casinos.
The traditional rule is that the superior one armed bandits were installed just inside the main door of the casino; so that persons going by would be able to see real jackpot winners and be convinced to come inside … play. Our inference is that this is definitely no longer the case.
Many of the major casinos today are giant complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ one armed bandits in close proximity to any doors.
An additional classic rule is that loose slot machines are installed on the major aisles in the casinos, again so that more people could see winning jackpots and be roused to play. Importantly 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 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 philosophy about where to place the loose slot machines.
