Volumes have been set forth on this matter, and the conflict and discord about where the "hot" slot machines are positioned in a casino are still on-going – over 60 years after slot machine games were first added to the gaming floor in casinos.
The traditional rule is that the superior slots were placed just inside the main entry of the casino; so that folks passing by would be able to see real jackpot winners … be possessed to come unto the gaming floor … play. Our determination is that this is definitely no longer true.
Many of the big name casinos presently are magnificent complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machines near to any exits.
Yet another standard rule is that loose slots are located on the major aisles in the casinos, again so that more people could see winning jackpots and be influenced to play. Notably however, 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 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!
These days, casinos are constantly changing their perspective about where to place the loose slots.
