Volumes have been set forth on this issue, and the conflict and discourse about where the "hot" slot machines are installed in the casino are still raging – more than 60 years after slots were 1st placed in gambling dens.
The classic rule is that the very best slot games were located just inside the entrance of the casino; so that casino fanatics walking by would see actual jackpot winners and be attracted to come unto the gambling floor and play. Our position is that this is definitely no longer true.
Practically all of the large casinos these days are massive complexes … it is not possible to see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ one armed bandits close-by any exits.
Yet another standard rule is that loose slots are installed on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be inspired to play. Interestingly though, 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 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 one armed bandits.
