Books have been written on this matter, and the disquiet and interchanges about where the "hot" one armed bandits are positioned in the casino are still ongoing – over 60 years after slot machine games were 1st placed in gambling dens.

The classic rule is that the more favourable slots were positioned just inside the main doorway of the casino; so that people passing by would be able to see real jackpot winners … be enticed to come inside and play. Our conviction is that this is definitely no longer true.

Almost 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 situate the ‘loose’ slot games close to any entrances.

Yet another classic rule is that loose slot machine games are located on the major aisles in the casinos, again so that more folks could see winning jackpots and be inspired to play. Importantly though, we find that this also isn’t 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 machine 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 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!

These days, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
