Volumes have been written on this issue, and the bickering and ruckus about where the "hot" slot machine games are installed in the casino are still raging – sixty years after slot machines were first placed in casinos.
The quintessential rule is that the most favorable slot games were put just inside the door of the casino; so that everyone going by would be able to see actual jackpot winners and be drawn to come unto the gaming floor … play. Our verdict is that this is definitely no longer true.
Almost all of the large casinos presently are gigantic complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot machine games near any doors.
Another traditional rule is that loose one armed bandits are installed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be galvanized to play. However, 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 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!
These days, casinos are constantly changing their perspective about where to place the loose slot games.
