Volumes have been written on this item, and the debates and interchanges about where the "hot" slots are positioned in the casino are still there – 60 yrs after the slot machines were 1st placed in the casinos.
The classic rule is that the better slots were installed just inside the entrance of the casino; so that individuals passing by would see jackpot winners and be enthralled to come into the casino and play. Our assurance is that this is definitely no longer true.
Just about all of the large casinos today are herculean complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot games near any of the doors.
Another standard rule is that loose one armed bandits are placed on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be roused to play. Notably though, we find that this also is not 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 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 perspective about where to place the loose slot games.
