Volumes have been written on this issue, and the bickering and disharmony about where the "hot" slot games are located in the casino are still ongoing – more than sixty years after slot machine games were first added to the gaming floor in casinos.
The standard rule is that the superior slots were located just inside the entry of the casino; so that fun seekers passing by would see real jackpot winners and be captivated to come unto the gambling floor … play. Our determination is that this is no longer the case.
The great majority of the mega casinos presently are huge complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games close to any of the doors.
An additional standard rule is that loose slots are placed on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be galvanized to play. Notably 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 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose slot machine games.
