Volumes have been stated on this issue, and the contention and arguments about where the "hot" slot games are installed in the casino are still raging – over sixty years after slot machines were 1st added to the gaming floor in gambling houses.
The quintessential rule is that the very best one armed bandits were located just inside the main door of the casino; so that casino fanatics passing by would be able to see jackpot winners … be baited to come unto the gambling floor and play. Our stance is that this is no longer true.
Most of the major casinos today are humongous complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machines near any entrances or exits.
Yet another classic rule is that loose one armed bandits are located on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be motivated to play. Importantly though, 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 slot machine games 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.
