Books have been said on this topic, and the debates and interchanges about where the "hot" slot machines are positioned in a casino are still raging – 60 years after slot machine games were first placed in the casinos.

The quintessential rule is that the best slot machines were installed just inside the entrance of the casino; so that potential players walking by would be able to see actual jackpot winners … be stimulated to come inside … play. Our sentiment is that this is no longer true.

Just about all of the major casinos these days are immense complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machine games in close proximity to any doorways.

Yet another standard rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be inspired to play. Interestingly 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 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!

In recent times, casinos are constantly changing their philosophy about where to place the loose slot machines.
