Volumes have been written on this issue, and the debates and feuds about where the "hot" slot machine games are located in a casino are still intense – over sixty yrs after the slot machines were 1st added to the gaming floor in gambling houses.
The quintessential rule is that the better slot games were put just inside the entry of the casino; so that fun seekers going by would see actual jackpot winners and be titillated to come into the casino and play. Our sentiment is that this is no longer true.
Almost all of the big name casinos nowadays are huge complexes … it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machine games near any entrances or exits.
Another classic rule is that loose slot machine games are located on the major aisles inside the casinos, again so that more people could see winning jackpots and be energized to play. Nonetheless, 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 one armed bandits 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose one armed bandits.
