Volumes have been set forth on this item, and the controversy and discussion about where the "hot" slot games are placed in a casino are still on-going – more than sixty yrs after the slots were 1st placed in the casinos.
The traditional rule is that the superior slot games were put just inside the entrance of the casino; so that persons walking by would see actual jackpot winners … be infatuated enough to come inside and play. Our reasoning is that this is definitely no longer the case.
Practically all of the big name casinos these days are magnificent complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machine games close to any doors.
Yet another traditional rule is that loose slot games are installed on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be influenced to play. Nonetheless, 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 perspective about where to place the loose one armed bandits.
