Volumes have been said on this issue, and the debates and ruckus about where the "hot" video slots are located in a casino are still intense – sixty years after slots were first placed in gambling houses.
The quintessential rule is that the more favourable slot machines were placed just inside the main entry of the casino; so that potential players walking by would be able to see real jackpot winners and be infatuated enough to come into the casino … play. Our assurance is that this is not so anymore.
Almost all of the mega casinos nowadays are huge complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slots close-by any exits.
Another traditional rule is that loose one armed bandits are put on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. However, 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 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose slot games.
