Books have been stated on this topic, and the disquiet and disharmony about where the "hot" slots are installed in the casino are still there – sixty years after the slots were first placed in casinos.

The traditional rule is that the superior slots were placed just inside the entrance of the casino; so that individuals going by would see actual jackpot winners and be smitten to come unto the gaming floor and play. Our assessment is that this is definitely no longer true.

The great majority of the major casinos these days are behemothic complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot games near 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 people could see winning jackpots and be roused 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 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.
