Books have been written on this topic, and the conflict and discussion about where the "hot" video slots are positioned in the casino are still raging – over sixty yrs after the slots were first placed in gambling houses.

The traditional rule is that the more favourable slot machine games were placed just inside the main entryway of the casino; so that fun seekers walking by would see real jackpot winners … be stimulated to come unto the gaming floor and play. Our theorem is that this is definitely no longer the case.

The great majority of the mega casinos today are enormous complexes … now you can’t see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machines close-by any entrances.

Yet another classic rule is that loose slot machines are installed on the major aisles in the casinos, again so that more people could see winning jackpots and be influenced to play. Interestingly 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 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!

In recent times, casinos are constantly changing their perspective about where to place the loose slot machines.
