Books have been stated on this subject, and the disquiet and discourse about where the "hot" slot machine games are located in the casino are still raging – 60 yrs after slot machines were 1st placed in casinos.
The standard rule is that the very best one armed bandits were put just inside the main entry of the casino; so that potential gamblers walking by would be able to see actual jackpot winners … be tempted to come unto the gambling floor and play. Our philosophy is that this is not so anymore.
Most of the major casinos nowadays are gigantic complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slots in close proximity to any entrances.
Another traditional rule is that loose one armed bandits are placed on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. Notably 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 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 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 machine games.
