Volumes have been written on this subject, and the bickering and discourse about where the "hot" slot machine games are positioned in a casino are still passionate – more than sixty years after one armed bandits were first installed in gambling houses.
The classic rule is that the most favorable one armed bandits were placed just inside the entrance of the casino; so that everyone going by would see actual jackpot winners and be enthralled to come into the casino … play. Our viewpoint is that this is no longer the case.
The majority of the big name casinos these days are humongous complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machine games close to any exits.
Another classic rule is that loose one armed bandits are put on the major aisles in the casinos, again so that more people could see winning jackpots and be roused to play. Interestingly 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 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose slot games.
