Volumes have been written on this issue, and the conflict and disharmony about where the "hot" slot machine games are installed in a casino are still bubbling – over sixty years after slot games were first installed in the casinos.
The traditional rule is that the more favourable one armed bandits were located just inside the main doorway of the casino; so that potential players going by would see actual jackpot winners … be enthralled to come inside and play. Our finding is that this is not so anymore.
Almost all of the mega casinos presently are grand complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games near any doors.
Another traditional rule is that loose slot games are installed on the major aisles inside the casinos, again so that more folks could see winning jackpots and be encouraged to play. Notably though, we find that this also is no longer a universal rule.
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 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.
