Books have been written on this topic, and the conflict and arguments about where the "hot" slots are located in a casino are still ongoing – over 60 yrs after slot machine games were first placed in gambling dens.

The standard rule is that the very best slot machines were put just inside the main entryway of the casino; so that casino fanatics passing by would be able to see real jackpot winners and be smitten to come unto the gambling floor and play. Our sentiment is that this is definitely no longer the case.

Most of the mega casinos presently are huge complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot games close to any of the doors.

An additional traditional rule is that loose slots are placed on the major aisles inside the casinos, again so that more persons could see winning jackpots and be galvanized to play. Notably 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 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!

Nowadays, casinos are constantly changing their philosophy about where to place the loose slots.
