Books have been stated on this item, and the contention and discussion about where the "hot" slots are positioned in a casino are still intense – 60 yrs after slots were first placed in gambling dens.

The traditional rule is that the more favourable slot games were put just inside the main foyer of the casino; so that persons passing by would see jackpot winners … be stirred to come unto the gambling floor … play. Our disposition is that this is no longer true.

The majority of the mega casinos today are oversized complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slots close-by any exits.

An additional traditional rule is that loose slot games are put on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be energized 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!

In recent times, casinos are constantly changing their perspective about where to place the loose slot machine games.
