Volumes have been written on this matter, and the controversy and squabbling about where the "hot" slot games are positioned in a casino are still happening – sixty years after the slot machines were first installed in gambling dens.
The traditional rule is that the very best one armed bandits were put just inside the main foyer of the casino; so that everyone passing by would see real jackpot winners and be tempted to come unto the gambling floor … play. Our conviction is that this is no longer the case.
The majority of the large casinos presently are oversized complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machines near to any doors.
An additional classic rule is that loose slots are put on the major aisles in the casinos, again so that more people 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 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 slot games.
