Books have been set forth on this topic, and the debates and discussion about where the "hot" video slots are installed in the casino are still rampant – more than sixty years after slots were 1st placed in the casinos.
The quintessential rule is that the most favorable slot machines were located just inside the main door of the casino; so that casino fanatics walking by would see real jackpot winners and be mesmerized enough to come inside … play. Our slant is that this is no longer the case.
Nearly all of the large casinos presently are herculean complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games in close proximity to any doors.
Yet another traditional rule is that loose slot machines are put on the major aisles in the casinos, again so that more folks could see winning jackpots and be roused to play. However, 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 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!
These days, casinos are constantly changing their perspective about where to place the loose slot games.
