Books have been set forth on this issue, and the controversy and squabbling about where the "hot" video slots are positioned in a casino are still happening – over sixty years after the slots were first added to the gaming floor in casinos.
The traditional rule is that the most favorable one armed bandits were put just inside the main entryway of the casino; so that folks going by would see actual jackpot winners and be drawn to come into the casino and play. Our resolve is that this is not so anymore.
The majority of the mega casinos nowadays are huge complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slot games close-by any entrances.
Another classic rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be roused to play. Importantly though, 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 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!
Today, casinos are constantly changing their perspective about where to place the loose slot games.
