Books have been said on this topic, and the disquiet and disagreement about where the "hot" slot machine games are located in the casino are still intense – 60 yrs after slot machine games were 1st placed in casinos.

The classic rule is that the best slots were installed just inside the main entrance of the casino; so that fun seekers going by would be able to see actual jackpot winners … be titillated to come unto the gaming floor … play. Our theory is that this is not so anymore.

The majority of the big name casinos presently are super-colossal complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slots close to any entrances or exits.

Yet another standard rule is that loose slots are installed on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be roused to play. Importantly 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 the 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!

These days, casinos are constantly changing their philosophy about where to place the loose slot machine games.
