Volumes have been stated on this matter, and the contention and squabbling about where the "hot" video slots are positioned in the casino are still bubbling – 60 years after slot games were 1st installed in the casinos.
The traditional rule is that the very best one armed bandits were positioned just inside the main door of the casino; so that potential gamblers walking by would be able to see real jackpot winners and be mesmerized enough to come unto the gambling floor … play. Our resolution is that this is definitely no longer true.
Many of the big name casinos these days are huge complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot games near any of the doors.
Another standard rule is that loose slot machines are installed on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be energized 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 the slot machines 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.
