Volumes have been set forth on this issue, and the debates and discourse about where the "hot" slot machines are placed in a casino are still rampant – more than sixty years after the slot machines were 1st placed in casinos.
The standard rule is that the more favourable slot machine games were positioned just inside the main entrance of the casino; so that people passing by would be able to see jackpot winners … be infatuated enough to come inside and play. Our frame of mind is that this is definitely no longer the case.
Practically all of the big name casinos presently are immense complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots close-by any entrances.
Another standard rule is that loose slot machine games are installed on the major aisles in the casinos, again so that more persons could see winning jackpots and be galvanized 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 one armed bandits 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 slot machines.
