Volumes have been set forth on this item, and the debates and disagreement about where the "hot" one armed bandits are placed in a casino are still taking place – more than sixty yrs after slot machines were first added to the gaming floor in the casinos.
The standard rule is that the most favorable slots were put just inside the main entrance of the casino; so that casino fanatics walking by would see actual jackpot winners and be challenged to come into the casino and play. Our persuasion is that this is definitely no longer true.
Many of the major casinos today are enormous complexes and it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slots in close proximity to any of the doors.
Yet another traditional rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more people could see winning jackpots and be motivated 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 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slots.
