Volumes have been written on this subject, and the disquiet and feuds about where the "hot" slot games are placed in a casino are still passionate – more than sixty years after slot machine games were 1st placed in casinos.
The traditional rule is that the most favorable slot games were installed just inside the entry of the casino; so that individuals passing by would be able to see real jackpot winners and be captivated to come unto the gaming floor … play. Our standpoint is that this is definitely no longer true.
The great majority of the large casinos nowadays are gigantic complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ one armed bandits in close proximity to any of the doors.
Another classic rule is that loose slot machine games are positioned on the major aisles inside the casinos, again so that more persons could see winning jackpots and be motivated to play. Importantly however, we find that this also is no longer a universal rule.
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 slot machines 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 machine games.
