Books have been written on this item, and the contention and arguments about where the "hot" slot machines are positioned in the casino are still bubbling – over 60 years after slot machines were first placed in casinos.

The traditional rule is that the best slots were installed just inside the main entrance of the casino; so that potential gamblers passing by would see jackpot winners … be captivated to come unto the gambling floor … play. Our estimation is that this is definitely no longer so.

Nearly all of the large casinos today are gigantic complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot games near to any doorways.

Yet another standard rule is that loose slot machine games are located on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be inspired to play. However, 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 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 perspective about where to place the loose one armed bandits.
