Books have been set forth on this topic, and the controversy and interchanges about where the "hot" slot machine games are positioned in a casino are still ongoing – over sixty years after slot games were first added to the gaming floor in casinos.
The classic rule is that the most favorable slot machine games were installed just inside the entrance of the casino; so that casino fanatics walking by would be able to see jackpot winners … be smitten to come unto the gambling floor … play. Our point of view is that this is definitely no longer the case.
Nearly all of the mega casinos these days are gigantic complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot games near to any exits.
An additional traditional rule is that loose slots are positioned on the major aisles inside the casinos, again so that more persons could see winning jackpots and be energized to play. Importantly 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 slot machine games 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 one armed bandits.
