Books have been set forth on this issue, and the conflict and discourse about where the "hot" one armed bandits are installed in the casino are still raging – over 60 years after slot machines were 1st added to the gaming floor in gambling houses.

The quintessential rule is that the better slot games were installed just inside the entry of the casino; so that persons passing by would be able to see real jackpot winners … be keen enough to come inside and play. Our inclination is that this is definitely no longer true.

Almost all of the big name casinos today are giant complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machines close to any entrances.

An additional traditional rule is that loose slot games are placed on the major aisles in the casinos, again so that more people could see winning jackpots and be influenced to play. Importantly 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 one armed bandits 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 slots.
