Volumes have been stated on this topic, and the bickering and ruckus about where the "hot" slot games are positioned in a casino are still intense – more than sixty years after slot machine games were 1st placed in casinos.
The traditional rule is that the very best slot games were put just inside the door of the casino; so that individuals walking by would be able to see actual jackpot winners and be drawn to come unto the gaming floor … play. Our disposition is that this is definitely no longer true.
Nearly all of the mega casinos nowadays are monstrous complexes … you can no longer see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ one armed bandits near to any entrances.
An additional classic rule is that loose slots are put on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Nonetheless, 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 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 machines.
