Volumes have been set forth on this topic, and the bickering and feuds about where the "hot" slot machine games are positioned in the casino are still there – more than 60 years after slot games were first placed in gambling dens.
The traditional rule is that the better slot games were located just inside the main entryway of the casino; so that folks passing by would be able to see real jackpot winners … be enthralled to come unto the gambling floor and play. Our assurance is that this is not so anymore.
Practically all of the large casinos presently are super-colossal complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot games close to any doors.
Yet another traditional rule is that loose one armed bandits are installed on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. Importantly however, 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 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 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 philosophy about where to place the loose slots.
