Books have been stated on this subject, and the debates and disharmony about where the "hot" slot machine games are located in a casino are still raging – over sixty yrs after the slot machines were 1st placed in gambling dens.
The classic rule is that the very best one armed bandits were located just inside the entrance of the casino; so that potential gamblers passing by would see jackpot winners and be stirred to come into the casino and play. Our observation is that this is definitely no longer true.
Just about all of the big name casinos presently are super-colossal complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot machine games close-by any entrances.
An additional traditional rule is that loose slot machine games are located on the major aisles in the casinos, again so that more persons could see winning jackpots and be energized 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!
Nowadays, casinos are constantly changing their perspective about where to place the loose one armed bandits.
