Books have been stated on this matter, and the debates and arguments about where the "hot" one armed bandits are placed in a casino are still happening – over sixty yrs after slot games were 1st placed in gambling houses.
The standard rule is that the most favorable slot games were installed just inside the main door of the casino; so that folks walking by would see real jackpot winners … be mesmerized enough to come unto the gaming floor … play. Our viewpoint is that this is no longer true.
Most of the mega casinos today are titanic complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machines in close proximity to any entrances.
Yet another traditional rule is that loose slot machine games are placed on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. Notably though, we find that this also isn’t 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 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slot machines.
