Volumes have been said on this item, and the controversy and arguments about where the "hot" video slots are placed in the casino are still taking place – over 60 yrs after slot machines were first installed in gambling houses.
The classic rule is that the most favorable slot machines were placed just inside the main foyer of the casino; so that individuals walking by would be able to see actual jackpot winners … be challenged to come unto the gaming floor and play. Our point of view is that this is no longer the case.
The great majority of the large casinos nowadays are behemothic complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ one armed bandits close-by any doorways.
Yet another traditional rule is that loose slot machine games are positioned on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be roused to play. 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 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 slot machine games.
