Volumes have been stated on this topic, and the debates and feuds about where the "hot" slot games are located in a casino are still there – over 60 years after slot games were first added to the gaming floor in the casinos.
The standard rule is that the more favourable slot machines were installed just inside the main entry of the casino; so that casino fanatics walking by would be able to see real jackpot winners and be enthralled to come inside … play. Our feeling is that this is not so anymore.
Just about all of the big name casinos these days are super-colossal complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot machines close-by any doors.
Another classic rule is that loose slot machines are placed on the major aisles inside the casinos, again so that more people could see winning jackpots and be roused to play. Nonetheless, 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 slot machines 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 philosophy about where to place the loose slot games.
