Volumes have been set forth on this item, and the conflict and face-offs about where the "hot" slots are placed in the casino are still raging – over 60 yrs after one armed bandits were 1st installed in gambling houses.
The standard rule is that the more favourable one armed bandits were positioned just inside the main doorway of the casino; so that potential players going by would be able to see actual jackpot winners … be stirred to come unto the gaming floor and play. Our philosophy is that this is definitely no longer so.
The great majority of the mega casinos today are humongous complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot games close to any entrances or exits.
Another classic rule is that loose slots are put on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be motivated 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 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!
These days, casinos are constantly changing their perspective about where to place the loose slot games.
