Volumes have been set forth on this topic, and the controversy and squabbling about where the "hot" one armed bandits are positioned in the casino are still taking place – sixty yrs after one armed bandits were first installed in gambling dens.
The traditional rule is that the better slot machines were installed just inside the main door of the casino; so that everyone going by would see actual jackpot winners and be stirred to come unto the gaming floor and play. Our persuasion is that this is no longer true.
The majority of the major casinos presently are behemothic complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slot games near any entrances or exits.
Yet another traditional rule is that loose slot games are located on the major aisles in the casinos, again so that more people could see winning jackpots and be inspired to play. Importantly 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 machine 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 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 perspective about where to place the loose slot machine games.
