Books have been stated on this topic, and the disquiet and feuds about where the "hot" slot machine games are positioned in the casino are still rampant – more than sixty years after slots were first placed in gambling houses.

The traditional rule is that the very best slots were put just inside the main entrance of the casino; so that everyone walking by would be able to see real jackpot winners … be possessed to come inside and play. Our finding is that this is definitely no longer so.

Just about all of the large casinos these days are huge complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot machine games close to any of the doors.

An additional traditional rule is that loose slots are put on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Notably however, 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 the slot machines 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!

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