Volumes have been said on this topic, and the controversy and face-offs about where the "hot" one armed bandits are located in a casino are still ongoing – over sixty yrs after slot machines were first added to the gaming floor in the casinos.
The standard rule is that the most favorable slot games were put just inside the door of the casino; so that individuals passing by would be able to see actual jackpot winners and be keen enough to come into the casino … play. Our opinion is that this is not so anymore.
The great majority of the big name casinos these days are herculean complexes … now you can’t see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot machine games close to any doors.
Another standard rule is that loose slot games are positioned on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be motivated to play. Importantly however, 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!
In recent times, casinos are constantly changing their perspective about where to place the loose one armed bandits.
