Books have been said on this item, and the controversy and discussion about where the "hot" slot machine games are placed in the casino are still intense – more than 60 years after slots were first placed in the casinos.
The standard rule is that the superior slot machine games were installed just inside the main entryway of the casino; so that people walking by would be able to see real jackpot winners … be smitten to come inside … play. Our sentiment is that this is no longer the case.
The great majority of the large casinos nowadays are immense complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machine games in close proximity to any entrances or exits.
Yet another standard rule is that loose one armed bandits are positioned on the major aisles in the casinos, again so that more persons could see winning jackpots and be motivated 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 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 philosophy about where to place the loose slot games.
