Books have been stated on this subject, and the debates and interchanges about where the "hot" slot machine games are installed in the casino are still bubbling – over sixty yrs after slot machine games were 1st placed in gambling dens.
The classic rule is that the most favorable slot machine games were put just inside the entry of the casino; so that potential players passing by would see actual jackpot winners … be enthralled to come unto the gambling floor … play. Our reckoning is that this is no longer the case.
The majority of the big name casinos today are colossal complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot games close to any of the doors.
Yet another traditional rule is that loose slot machine games are installed on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be motivated 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 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 perspective about where to place the loose slot games.
