Books have been said on this topic, and the disquiet and squabbling about where the "hot" video slots are located in a casino are still happening – sixty years after the slot machines were first installed in the casinos.

The quintessential rule is that the most favorable slot machines were located just inside the entry of the casino; so that casino fanatics passing by would see actual jackpot winners and be stirred to come into the casino … play. Our theorem is that this is not so anymore.

Practically all of the big name casinos today are gigantic complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot games near to any entrances or exits.

An additional classic rule is that loose slot games are installed on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be roused 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 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!

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