Volumes have been set forth on this item, and the contention and disharmony about where the "hot" one armed bandits are located in the casino are still there – over sixty yrs after the slot machines were first placed in the casinos.
The traditional rule is that the superior slot machine games were placed just inside the main door of the casino; so that individuals walking by would be able to see jackpot winners … be stirred to come unto the gambling floor … play. Our persuasion is that this is no longer the case.
The majority of the large casinos these days are herculean complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ one armed bandits close to any entrances.
Another classic rule is that loose slots are put on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be roused to play. However, we find that this also is no longer a universal rule.
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 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
