Volumes have been set forth on this matter, and the disquiet and discourse about where the "hot" slot games are placed in the casino are still intense – over 60 yrs after slot machine games were first installed in the casinos.
The classic rule is that the very best slots were positioned just inside the main entrance of the casino; so that persons going by would be able to see real jackpot winners and be influenced to come inside and play. Our feeling is that this is definitely no longer true.
Many of the big name casinos nowadays are monstrous complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ one armed bandits close to any exits.
Yet another classic rule is that loose slot machines are positioned on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. Nonetheless, we find that this also is no longer a universal rule.
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 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!
Today, casinos are constantly changing their perspective about where to place the loose one armed bandits.
