Books have been stated on this matter, and the bickering and face-offs about where the "hot" one armed bandits are placed in a casino are still bubbling – more than sixty yrs after slot machine games were first installed in gambling dens.
The quintessential rule is that the superior slots were positioned just inside the entry of the casino; so that individuals walking by would be able to see real jackpot winners … be attracted to come inside and play. Our estimation is that this is definitely no longer so.
Most of the mega casinos nowadays are enormous complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ one armed bandits close to any doorways.
Another traditional rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more folks could see winning jackpots and be energized to play. Interestingly though, 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 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!
Today, casinos are constantly changing their philosophy about where to place the loose slot machine games.
