Volumes have been said on this subject, and the contention and feuds about where the "hot" slot machine games are placed in the casino are still there – over sixty years after the slot machines were first placed in gambling houses.
The standard rule is that the better slots were positioned just inside the entrance of the casino; so that individuals going by would see real jackpot winners and be attracted to come unto the gambling floor … play. Our slant is that this is definitely no longer so.
Just about all of the mega casinos these days are monstrous complexes … it is not possible to see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slot machines close-by any entrances or exits.
An additional classic rule is that loose one armed bandits are located on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be motivated to play. Nonetheless, 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slot machine games.
