Volumes have been written on this matter, and the bickering and interchanges about where the "hot" one armed bandits are placed in a casino are still raging – more than sixty years after one armed bandits were first added to the gaming floor in casinos.
The classic rule is that the better slot games were placed just inside the main foyer of the casino; so that individuals walking by would see jackpot winners … be intrigued enough to come unto the gambling floor and play. Our verdict is that this is no longer true.
Almost all of the mega casinos nowadays are colossal complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slots in close proximity to any of the doors.
Yet another traditional rule is that loose one armed bandits are put on the major aisles in the casinos, again so that more people could see winning jackpots and be galvanized to play. Notably though, we find that this also is not 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!
Today, casinos are constantly changing their philosophy about where to place the loose slot machines.
