Volumes have been set forth on this topic, and the disquiet and arguments about where the "hot" video slots are installed in a casino are still taking place – over sixty years after the slots were 1st placed in casinos.
The traditional rule is that the most favorable slot games were placed just inside the main foyer of the casino; so that potential players walking by would be able to see jackpot winners and be drawn to come unto the gambling floor … play. Our persuasion is that this is not so anymore.
The great majority of the large casinos nowadays are super-colossal complexes and you can no longer see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machine games close to any exits.
An additional traditional rule is that loose slot machines are placed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be inspired to play. Nonetheless, 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 philosophy about where to place the loose slot games.
