Volumes have been said on this matter, and the conflict and ruckus about where the "hot" slot machines are installed in a casino are still bubbling – more than sixty years after one armed bandits were first installed in gambling dens.
The classic rule is that the very best slots were positioned just inside the door of the casino; so that individuals going by would be able to see jackpot winners and be influenced to come unto the gambling floor … play. Our sneaking suspicion is that this is definitely no longer the case.
Most of the mega casinos nowadays are massive complexes … you can no longer see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machines near to any entrances or exits.
Yet another classic rule is that loose slot games are located on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Notably 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 the slots 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!
In recent times, casinos are constantly changing their perspective about where to place the loose one armed bandits.
