Volumes have been said on this subject, and the conflict and ruckus about where the "hot" slot machine games are located in the casino are still there – over 60 yrs after the slots were first placed in gambling houses.
The traditional rule is that the very best slots were placed just inside the main entry of the casino; so that everyone passing by would be able to see real jackpot winners and be intrigued enough to come into the casino … play. Our position is that this is definitely no longer the case.
Almost all of the major casinos today are enormous complexes and you can no longer see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ one armed bandits near to any entrances.
Yet another standard rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be inspired to play. Importantly though, we find that this also is not 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose slot machine games.
