Volumes have been stated on this matter, and the bickering and disharmony about where the "hot" slot machine games are located in a casino are still rampant – over sixty years after slot machines were 1st placed in gambling dens.
The classic rule is that the very best one armed bandits were placed just inside the main entryway of the casino; so that persons walking by would be able to see real jackpot winners … be enticed to come unto the gaming floor … play. Our verdict is that this is definitely no longer so.
Many of the major casinos these days are immense complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots close to any exits.
Yet another classic 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 encouraged 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 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!
These days, casinos are constantly changing their philosophy about where to place the loose slots.
