Volumes have been stated on this topic, and the conflict and discourse about where the "hot" slots are placed in the casino are still intense – 60 yrs after slot machines were 1st placed in the casinos.

The standard rule is that the most favorable slot machine games were put just inside the main door of the casino; so that people walking by would see real jackpot winners … be impressed enough to come inside and play. Our perspective is that this is definitely no longer so.

Most of the major casinos nowadays are titanic complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ one armed bandits close-by any doors.

Another traditional rule is that loose slots are placed on the major aisles in the casinos, again so that more people could see winning jackpots and be inspired to play. Interestingly 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 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 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 philosophy about where to place the loose slot machine games.
